In the pair of given angles, the value of 2x and x is 52° and 26°.
What are angles?When two straight lines or rays intersect at a single endpoint, an angle is created. The vertex of an angle is the location where two points come together. The Latin word "angulus," which means "corner," is where the word "angle" originates. The names of fundamental angles include acute, obtuse, right, straight, reflex, and full rotation. A geometrical shape called an angle is created by joining two rays at their termini. In most cases, an angle is expressed in degrees. In geometry, there are several different kinds of angles.So, the value of 2x and x:
We know that the given pair of angles is an exterior alternate angle.A pair of exterior alternate angles is always 180°.Now, solve for x and 2x as follows:
2x + 128 = 1802x = 180 - 1282x = 52°x = 52/2x = 26°Therefore, in the pair of given angles, the value of 2x and x is 52° and 26°.

In ▲ABC, side AC is extended through C to D. If m<dcb=50 which is the longest side of triangle abc?
Answer:
AB
Step-by-step explanation:
the angles DCB and ACB are supplementary angles (together 180°).
simply because the sum of all angles around a single point on one side of a line is suggests 180° (it represents a half-circle).
so, the inner angle ACB is
ACB = 180 - 50 = 130°
because the sum of all angles in a triangle is also always 180°, there are only 50° left for the other 2 angles.
so, the inner angle at C is clearly the largest angle in the triangle ABC.
the larger an angle, the longer the opposing side.
the largest angle has the longest opposing side in the triangle.
the opposing side of the inner angle C is AB. and that is therefore the longest side in the triangle ABC.

The required measures of the angle A, L, and J is 40.8°, 83°, and 95° respectively.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
1.
The sum of the vertical angle is 180°. So,
∠A + ∠B = 180
Substitute value in the above equation,
x + 4x - 24 = 180
5x - 24 = 180
5x = 204
x = 204 / 5
x = 40.8°
∠A = 40.8°
Similarly,

Jane has a pre-paid cell phone with NextFell. She can't remember the exact costs, but her plan has a monthly fee and a charge for each minute of calling time. In June she used 200 minutes and the cost was $75.00. In July she used 680 minutes and the cost was $195.00.
We are given that Jane used 200 minutes and the cost was $75, and also she used 680 minutes and the cost was $195. To determine a function of the cost "C" as a function of the minutes "x" we will assume that the behavior of this function is that of a line. Therefore, the function must have the following form:
[tex]C(x)=mx+b[/tex]Where "m" is the slope and "b" the y-intercept. We will determine the slope using the following formula:
[tex]m=\frac{C_2-C_1}{x_2-x_1}[/tex]Where:
[tex](x_1,C_1),(x_2,C_2)[/tex]Are points in the line. The given points are:
[tex]\begin{gathered} (x_1_{},C_1)=(200,75) \\ (x_2,C_2)=(680,195) \end{gathered}[/tex]Substituting in the formula for the slope we get:
[tex]m=\frac{195-75}{680-200}[/tex]Solving the operations we get:
[tex]m=\frac{120}{480}=\frac{1}{4}[/tex]Now we substitute in the formula for the line:
[tex]C(x)=\frac{1}{4}x+b[/tex]Now we determine the value if "b" by substituting the first point. This means that when C = 200, x = 75.
[tex]200=\frac{1}{4}(75)+b[/tex]Solving the product:
[tex]200=18.75+b[/tex]Now we subtract 18.75 from both sides:
[tex]\begin{gathered} 200-18.75=b \\ 181.25=b \end{gathered}[/tex]Therefore, the formula of the cost is:
[tex]C(x)=\frac{1}{4}x+181.25[/tex]Part B. We are asked to determine the cost is there is a consumption of 323 minutes. To do that we will substitute in the formula for "C" the value of x = 323.
[tex]C(323)=\frac{1}{4}(323)+181.25[/tex]Solving the operations we get:
[tex]C(323)=262[/tex]Therefore, the cost is $262.
Answer:
Step-by-step explanation:
We will make use of algebra here.
First of all, we know that the monthly fee will be the same throughout all the months.
So, let's consider that cost to be the yet-to-find constant: [tex]a[/tex].
A charge is accumulated for every minute on the call, so let's consider that minutely charge to be the constant: [tex]b[/tex].
[tex]x[/tex] is the number of minutes spent on the call.
So, the total charge after talking for [tex]x[/tex] minutes would be:
[tex]b \times x\\=bx[/tex]
The monthly cost is the sum of the monthly fee and the total charge.
So, if this is represented mathematically, we get:
[tex]C(x)= a+bx[/tex]
A piece of information that we have is that, after calling for 200 minutes (which means [tex]x=200[/tex]), the monthly cost ( [tex]C(x)[/tex] ) would be $75.
Upon substituting these values in the equation we found above, we get:
[tex]C(x)=a+bx\\\\75=a+200b[/tex]
Similarly, we have another piece of information, which states that calling for 680 minutes ([tex]x=680[/tex]) produced a monthly cost of $195.
Upon substituting these values in the equation we found above, we get:
[tex]C(x)=a+bx\\\\195=a+680b[/tex]
And, thus we have found a system of equations:
[tex]a+200b=75\\a+680b=195[/tex]
For the first equation, let's make [tex]a[/tex] the subject:
[tex]a+200b=75\\\\a+200b-200b=75-200b\\\\a=75-200b[/tex]
Substitute this expression for [tex]a[/tex] into the second equation:
[tex]a+680b=195\\\\75-200b+680b=195\\\\75+480b=195[/tex]
Find the value of [tex]b[/tex] using this equation:
[tex]75+480b=195\\\\75+480b-75=195-75\\\\480b=120\\\\\frac{480b}{480}=\frac{120}{480}\\\\b=\frac{1}{4}[/tex]
Insert the value for [tex]b[/tex] into the expression for [tex]a[/tex]:
[tex]a=75-200b\\\\a=75-200(\frac{1}{4})\\\\a=75-50\\\\a=25[/tex]
Since we have the values for the constants [tex]a[/tex] and [tex]b[/tex], we can complete the function/equation [tex]C(x)[/tex]:
[tex]C(x)=a+bx\\\\C(x)=25+\frac{1}{4}x[/tex]
So, the answer for (A) is:
[tex]C(x)=25+\frac{1}{4}x[/tex]
For (B), we have to find the monthly bill/cost ( [tex]C(x)[/tex] ) when 323 minutes have been spent on calling.
So, we just have to substitute [tex]x[/tex] for 323, since [tex]x[/tex] represents the number of minutes spent on calling:
[tex]C(x)=25+\frac{1}{4}x\\\\C(x)=25+\frac{1}{4}(323)\\\\C(x)=25+80.75\\\\C(x)=100.75[/tex]
The answer for (B) is [tex]\$100.75[/tex]

2. Kieran, Jermaine and Chris play football. Kieran scored 8 more goals than Chris Jermaine scored 5 more goals than Kieran. Altogether they have scored 72 goals. How many goals did they each score?
Answer:
Step-by-step explanation:
k = x+8
c= x+5
j= x+5
3x+18=72
x = 18
Chris = 23
Kieran = 26
Jermaine = 23
Answer:
Chris = 17 goals
Kieran = 25 goals, and
Jermaine = 30 goals
Step-by-step explanation:
Let K, J, and C stand for the goals scored by Kieran, Jermaine, and Chris, respectively.
We learn that:
K = C + 8 [Kieran scored 8 more goals than Chris]
J = K + 5 [Jermaine scored 5 more goals than Kieran]
K + J + C = 72 [Altogether they have scored 72 goals]
-----
We have 3 equations and 3 unknowns. Therefore, we should be able to find a solution by rearranging and substituting.
Let's start with K + J + C = 72 and find ways to eliminate two of the three variables.
We can substitute for K since K = C + 8
K + J + C = 72
(C+8) + J + C = 72
Rearrange:
2C+8 + J = 72
We can also substitute for J since J = K + 5
2C+8 + J = 72
2C+8 + (K + 5) = 72
Again, we can substitute for K since (K = C + 8)
2C+8 + (C+8) + 5 = 72
2C+8 + (C+8) + 5 = 72
3C +21 = 72
3C = 51
C = 17
---
Since C = 17, we can find K with K = C + 8
K = C + 8
K = 17 + 8
K = 25
---
Since K = 25, we can find J with J = K + 5
J = K + 5
J = 25 + 5
J = 30
===
We find:
C (Chris) = 17 goals
K (Kieran) = 25 goals, and
J (Jermaine) = 30 goals
17 + 25 + 30 = 62 total goals.

2. What is the equation of a line that passes through the points (-0.92, 2.49) and (-5.62, 9.76)? Write your answer in point-slope form.
Answer:
Step-by-step explanation:
-0.92 2.49
-5.62 9.76
Rise = 9.76 - 2,49 = 7.27
Run: -5.62 - (-0.92) = -4.7
Slope (Rise/Run) = (7.27.`-0.92) = -1.55
The line has the form:
y = 1.55x + b
We need to find a value of b that forces the line through both point, Use one of the points and solve for b. I'll use (-0.92, 2.49).
y = 1.55x + b
2.49 = 1.55(-0.92) + b
b = 2.49 - 1.426 = 1.064
The equation is y = 1.55x + 1.0

Explanation: The basic property of the equation is that if you multiply or divide both sides of the equation by the non-zero whole , the equation still holds.
In the Equation : 4 (x - 2) =100 divide by 2 on both sides because 2 is common factor of (4,10)
So, 4(x - 2) =100
1/2 x 4(x-2) = 1/2 x 100

[tex]\begin{gathered} F=P(1+r)^n \\ P_2=9(1+0.4)^2 \\ P_2=9\times1.4^2 \\ P_2=17.64 \\ P_2\approx1\text{ decimal place} \\ P_2=17.6 \end{gathered}[/tex]Hence,
P2 = 17.6
Therefore,
The formula for Pn will be represented below as
[tex]\begin{gathered} P_n=9(1+0.4)^n \\ P_n=9(1.4)^n \end{gathered}[/tex]The explicit formula for Pn will be
[tex]P_n=9(1.4)^n[/tex]To figure out the values of P9. we will substitute the value of n=9 in the equation below
[tex]\begin{gathered} P_n=9(1.4)^n \\ P_9=9(1.4)^9 \\ P_9=185.9 \end{gathered}[/tex]Hence,
P9 = 185.9

A cylindrical drinking glass has radius 3 cm and height 8 cm. (i) Calculate the volume of water the glass holds when it is filled to the top.Give the units of your answer. Answer(a)(i); Water is poured into a number of these glasses from a jug containing 1.5 litres Each glass has a horizontal line 2 cm from the top. Calculate how many of these glasses can be filled up to the line from the jug
The volume of the glass is 454.16cm² and the number of glasses filled upto a horizontal line of 2 cm from top is 4
A cylindrical drinking glass has radius 3 cm and height 8 cm.
The volume of a cylinder is 2πr²h
= 2 (3.14) 3² x 8
= 452.16cm³
The jug contains 1.5 litres of water
1 litre = 1000cm³
1.5 litre = 1500cm³
The volume of glass if it is filled upto a horizontal line 2 cm from the top.
volume = 2πr²h
= 2 (3.14) 3² x 6
= 339.12cm³
Number of glasses filled = 1500/339.12 = 4.42
4 glasses can be filled up to the line from the jug
Therefore, the volume of the glass is 454.16cm² and the number of glasses filled upto a horizontal line of 2 cm from top is 4

Look at this graph What is the equation of the line in point slope form? Use the red point in your equation. Write your answer using integers, proper fractions, and improper fractions in simplest form. y - ____ = ____ (x - ____)
EXPLANATION
Given the line on the graph, we need to find the slope and the y-intercept.
Considering two ordered pairs, as for instance (x₁,y₁)=(50,-90) and (x₂,y₂)=(80,90)
The slope-equation is:
[tex]\text{Slope}=\frac{(y_2-y_1)}{(x_2-x_1)}[/tex]Replacing terms:
[tex]\text{Slope}=\frac{(90-(-90))}{(80-50)}=\frac{180}{30}=\frac{18}{3}=6[/tex]The point-slope form of the line is:
y-y₁= m(x-x₁)
Finally, we need to represent as a point-slope form considering either one ordered pair, as for instance, (x₁,y₁)=(50,-90)
y-(-90) = 6(x-50) [Simplifying terms]
y + 90 = 6(x-50) [ANSWER]
