The difference between 2 numbers is 8. The sum of the two numbers is 20. Find the number.
Answer:
The numbers are 6 and 14
Step-by-step explanation:
Let the two numbers be x and y
x-y = 8
x+y = 20
Add the two equations
x-y = 8
x+y = 20
-----------------
2x = 28
Divide by 2
2x/2 = 28/2
x = 14
Subtract the two equations
x-y = 8
-x-y = -20
-----------------
-2y = -12
Divide by -2
-2y/-2 = -12/-2
y = 6
The numbers are 6 and 14
Answer:
14, 6
Step-by-step explanation:
x-y =8 =>x=y+8
x+y=20
y+8 +y=20
2y=20 - 8
2y=12
y=12 :2
y=6 (the second number
x=6 +8 =14 (the first number

Gianna put $1000 in a savings account for 18 months, The interest on the account is 3.5%. How much will Gianna earn in interest? What amount will she have at the end of that time period?
Answer:
amount of interest = 52.5
amount at the end of the period = 1052.5
Step-by-step explanation:
use the formula for simple interest
PRT/100
P is the principle
R is the rate of interest charged
T is the Time taken
18 months = 1 years 6 months ( 1.5 years)
1000 * 3.5 * 1.5 = 5250
5250/100 = 52.5
the amount of interest = 52.5
the amount she will have at the end of the period
= 1000 +52.5
= 1052.5
* Describe how circle, parabola, ellipse, hyperbola are formed in a conic section. (include axis, vertex, vertical angles in a figure).
Step-by-step explanation:
In mathematics, a conic section (or simply conic) is a curve obtained as the intersection of the surface of a cone with a plane. The three types of conic section are the hyperbola, the parabola, and the ellipse; the circle is a special case of the ellipse, though historically it was sometimes called a fourth type. The ancient Greek mathematicians studied conic sections, culminating around 200 BC with Apollonius of Perga's systematic work on their properties.
Types of conic sections:
1. Parabola
2. Circle and ellipse
3. Hyperbola
Table of conics, Cyclopaedia, 1728
The conic sections in the Euclidean plane have various distinguishing properties, many of which can be used as alternative definitions. One such property defines a non-circular conic[1] to be the set of those points whose distances to some particular point, called a focus, and some particular line, called a directrix, are in a fixed ratio, called the eccentricity. The type of conic is determined by the value of the eccentricity. In analytic geometry, a conic may be defined as a plane algebraic curve of degree 2; that is, as the set of points whose coordinates satisfy a quadratic equation in two variables. This equation may be written in matrix form, and some geometric properties can be studied as algebraic conditions.
In the Euclidean plane, the three types of conic sections appear quite different, but share many properties. By extending the Euclidean plane to include a line at infinity, obtaining a projective plane, the apparent difference vanishes: the branches of a hyperbola meet in two points at infinity, making it a single closed curve; and the two ends of a parabola meet to make it a closed curve tangent to the line at infinity. Further extension, by expanding the real coordinates to admit complex coordinates, provides the means to see this unification algebraically.
Find the midpoint of line segment joining The points (-1,-3) and (-5,12)
Answer:
The answer is
[tex]( - 3 \: , \: \frac{9}{2} ) \\ [/tex]Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
[tex]M = ( \frac{x_1 + x_2}{2} , \: \frac{y_1 + y_2}{2} )\\[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-1,-3) and (-5,12)
The midpoint is
[tex]M = ( \frac{ - 1 - 5}{2} \: , \: \frac{ - 3 + 12}{2} ) \\ = ( - \frac{6}{2} \: , \: \frac{9}{2} )[/tex]
We have the final answer as
[tex]( - 3 \: , \: \frac{9}{2} ) \\ [/tex]
Hope this helps you
Step-by-step explanation:
Hey there!
The given coordinates are; (-1,-3) and (-5,12).
Now;
Use formula for midpoint.
[tex]m(x,y) = ( \frac{x1 + x2}{2} ,\frac{y1 + y2}{2} )[/tex]
Put all values.
[tex](x,y) = ( \frac{ - 1 - 5}{2} ,\frac{ - 3 + 12}{2} )[/tex]
Simplify it to get answer.
[tex](x,y) = ( \frac{ - 6}{2} , \frac{9}{2}) [/tex]
[tex](x,y) = ( - 3, \frac{9}{2} )[/tex]
Therefore the midpoint is; (-3,9/2).

What is the sum of the following?
88x+4y+2x+1y
Hey there!☺
[tex]\text{Answer: }\boxed{90x+5y}[/tex]
[tex]\textbf{\text{Explanation:}}[/tex]
[tex]88x+4y+2x+1y[/tex]
In our first step, we will need to identify like terms.
[tex]\textbf{88x}+4y+\textbf{2x}+1y \rightarrow \text{x variables are like terms}\\88x+\textbf{4y} + 2x + \textbf{1y} \rightarrow \text{y variables are like terms}[/tex]
Now that the like terms have been identified, we will need to add them. Adding variables are simple; you add the whole numbers while the variable says the same.
[tex]88x+2x=90x[/tex]
[tex]4y+1y=5y[/tex]
Now, we will add.
[tex]90x+5y[/tex]
The answer is 90x+5y.
Hope this helps! ☺
A family bought a total of 16 adult and child tickets to a magic show.adult tickets are 10.50 each and child tickets are 7.50 each .the family paid a total of $141
Answer:
There were 7 adults and 9 children paying tickets to the magic show
Step-by-step explanation:
System of Equations
A system of equations consists of more than one variable related to more than one equation. The question we're working on requires to know two variables: the number of children and the number of adults that paid to a magic show.
Let's call x to the number of adults and y to the number of children. The first condition states there are a total of 16 persons in the group. This can be written as:
[tex]x+y=16[/tex] [1]
We also know the adult tickets cost $10.50 each and child tickets cost $7.50 each. This means the total amount paid for the tickets is:
[tex]total\ paid = 10.50*x+7.50*y[/tex]
We are given this total, thus
[tex]10.50*x+7.50*y=141[/tex] [2]
The system formed by [1] and [2] must be solved to answer the question. Let's solve [1] for x:
[tex]x=16-y[/tex]
And substitute x in [2]:
[tex]10.50*(16-y)+7.50*y=141[/tex]
Operating:
[tex]10.50*16-10.50*y+7.50*y=141[/tex]
[tex]-10.50*y+7.50*y=141-10.50*16[/tex]
Joining like terms and operating on the right side:
[tex]-3y=-27[/tex]
Solving:
[tex]\displaystyle y=\frac{-27}{-3}[/tex]
[tex]\boxed{y=9}[/tex]
The value of x is calculated by
x=16-y=16-9
[tex]\boxed{x=7}[/tex]
This means there were 7 adults and 9 children paying tickets to the magic show
What is the vertex of the quadratic function y=-(x-3)^2+4
Answer:
vertex = (3, 4 )
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
y = - (x - 3)² + 4 ← is in vertex form
with (h, k ) = (3, 4 ) ← vertex

What is the change in temperature a customer in a grocery store experiences when they walk from the chilled vegetable section at 4oC to the frozen fish section which is set to -18oC?
A.-14oC
B.14oC
C.-22oC
D.22oC
Answer:
-22oC
Step-by-step explanation:
I hope you mean -22 degrees Celsius, because that almost tricked me. 4'C -22'C is equal to -18'C, so that means C is the answer.
Answer:
Temperature of vegetable section = 4°C
Temperature of fish section = −18°C
Change in temperature = 4°C − (−18°C) = 4°C + 18°C = 22°C

HELPPPP!!!! (20 points) The table below shows the account balances for four different customer accounts at the City
Bank. Which account balance represents a debt that is greater than $20 and less than $30?
Account Balance (S)
S25
-S34
-$24
$17
Answer:
$25
mark as brainlist answer
The account balance that represents a debt that is greater than $20 and less than $30 is -$24.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
We are given that;
The account balance= $20 and less than $30
Account Balance (S)
S25,-S34,-$24,$17
Now,
Note that a negative account balance indicates a debt, and the absolute value of the account balance represents the amount of the debt. In this case, the account balance of -$24 represents a debt of $24, which is greater than $20 and less than $30.
Therefore, by algebra the answer will be -$24.
