Each square on a grid represents 1 unit on each side. Match the numbers with the slopes of the lines.

50 POINTS + BRAINLY FOR CORRECT ANSWER!!!

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.

1. The scale is of 1:400,000.

2. The distance between A and B is of 36 km.

3. The diagram with city C is given at the end of the answer.

The scale of a drawing is how much each unit in the drawing represents in actual distance.

In the context of this problem, the scale is given as follows:

1 cm = 4 km

Meaning that each cm drawn represents 4 km of actual distance.

Using the same unit, we have that:

4 km = 4 x 100,000 cm = 400,000 cm.

Hence the scale is given by:

1:400,000.

Measuring on the drawing, the distance between A and B is of 9 cm, hence, applying the scale, the real distance is of:

9 x 4 km = 36 km.

In the diagram, considering the given scale, we want to position city C 3 cm from City A, to the west = to the left.

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.

The table that represents a linear function is Table 1. Thus, the correct option is A.

A linear equation is an equation in which each term has at max one degree. Linear equation in variable x and y can be written in the form y = mx + c.

Linear equation with two variables, when graphed on a cartesian plane with axes of those variables, give a straight line.

We know that, slope m= (y2-y1)/(x2-x1)

Table 1:

Put (x1, y1)=(1, 5) and (x2, y2)=(2, 9) in slope formula

That is, (9-5)/(2-1)

= 4

Similarly, the slope between last two points is (9-5)/(4-1)

=4

Table 2:

Put (x1, y1)=(1, -5) and (x2, y2)=(2, 10) in slope formula

That is, (10+5)/(2-1)

= 15

Similarly, slope between last two points (20+15)/(4-3)

=35

Hence, the table that represents a linear function is Table 1. Thus, the correct option is A.

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,

When a cardboard box is empty, its weight is 0.6 pounds.

It is filled with 15 bags of beans and a 4-pound bag of rice.

The total weight of the box and the contents inside it is 25.6 pounds.

Let the weight of 15 bean bags is 15b. The given scenario can be represented by the equation as follows :

0.6+15b+4=25.6 ....(A)

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:

Where "m" is the slope and "b" the y-intercept. We will determine the slope using the following formula:

Where:

Are points in the line. The given points are:

Substituting in the formula for the slope we get:

Solving the operations we get:

Now we substitute in the formula for the line:

Now we determine the value if "b" by substituting the first point. This means that when C = 200, x = 75.

Solving the product:

Now we subtract 18.75 from both sides:

Therefore, the formula of the cost is:

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.

Solving the operations we get:

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]
