Answer:
(-3, -1); x = -3; y = -1
Step-by-step explanation:
-3x + 5y = 4; x + y = -4
solving via substitution
rearrange second equation: y = -x - 4
-3x + 5(-x - 4) = 4
-3x - 5x - 20 = 4
-8x -20 = 4
-8x = 24
x = -3
- 3 + y = -4
y = -1
(-3, -1)
Check
- 3 + -1 = -4

Verizon charges $200 to start up a cell phone plan. then there is a $50 charge each month. what is the total cost for .x months
Answers
Answer:
200 + 50x
Step-by-step explanation:
depending on what x is, you multiply x by 50 and add 200, since 200 is the start up fee and the constant. the 50 dollars per month is a variable, since the more months you own the plan, the more money it would cost.

A line segment has endpoints F(2, 2) and G(8, 2) Find the coordinates of its midpoint M
Answers
Answer:
(5,2)
Step-by-step explanation:
The midpoint of a line segment is calculated by finding the average of the x values and the average of the y values of the endpoints.
[tex]midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )[/tex] when the points given are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug points F(2,2) and G(8,2) into the equation
[tex]midpoint=(\frac{2+8}{2},\frac{2+2}{2} )\\midpoint=(\frac{10}{2},\frac{4}{2} )\\midpoint=(5,2)[/tex]
Therefore, the midpoint of the line segment with endpoints F and G is (5,2).

How do you solve 13 + 3 - 8x + 6 = 1 - 5x I dont get it
Answers
Answer:
x = 7
Step-by-step explanation:
How to solve your question
Your question is 13 + 3 − 8x + 6 = 1 − 5x
13 +3 - 8x + 6 = 1 - 5x
13 + 3 − 8x + 6 = 1 − 5x
Solve
Add the numbers
13 + 3 − 8x + 6 = 1 − 5x
22 − 8x = 1 − 5x
Rearrange terms
22 − 8x = 1 − 5x
−8x + 22 = 1 − 5x
Subtract 22 from both sides of the equation
−8x + 22 −22 = −5x + 1 − 22
Simplify
Subtract the numbers
−8x = -5x + 1 -22
-8x = -5x -21
Add 5x to both sides of the equation
-8x + 5x = -5x -21 + 5x
Simplify
Combine like terms
-3x = -21
Divide both sides of the equation by the same term
(-3x)/3 = (-21)/3
Simplify
Cancel terms that are in both the numerator and denominator
x = (-21)/(-3)
Divide the numbers
x = 7
Answer: x=7

Answer:
i believe it is 73 degrees
Step-by-step explanation:
Answer:
73°
Step-by-step explanation:
All interior angles of a triangle add up to 180°
We are given the angle measure of 17°. Since the triangle is a right triangle, it's safe to assume that the second angle is 90°.
90 + 17 = 107
180 - 107 = 73
The third angle should be 73°. Hope this helps!

The amount paid for different weights of oranges at a farmer’s market are shown below.
Answers
Answer:
8
Step-by-step explanation:
Well just looking at the problem you can take the first line of data (2 pounds of oranges for $3) and divide that to get how much one orange would be.
So:
$3.00 / 2 = $1.50
So now we have :
1 pound of oranges = $1.50
With this info we can take the $12 on the fourth line and divide it by the price of one pound of oranges ($1.50).
Like so:
$12.00 / $1.50
=
8
We can check this by inputting the 8 on the ?
If we do so we get 8 (8 pounds of oranges) x $1.50 (Price per 1 pound of oranges) = $12.00, which matches up with the $12 price the problem has given us.
Hope this helps!

Step-by-step explanation:
First you make the fraction equal by multiplying them
2/3 multiply both numerator and denominator by 4
= 8/12
Now you divide 60 by 12 to find the amount to make the denominator 60
60 divided by 12 = 5
8/12 multiply both numerator and denominator by 5
= 40/60
So now we know the amounts

The area of the polynomial is 35 square unit.
Step-by-step explanation:
It is given that area of the polygon WXYZ with its vertices at W(–3, –2), X(–3, 5), Y(2, 5), and Z(2, –2)
From the below graph it is noticed that the given polynomial is a rectangle with length 5 and width 7
The distance formula
Using the above formula we get,
The length of opposing sides are equal
Using the Pythagoras theorem, the length of diagonal WY and XZ are
Since the length of the diagonal are same, therefore the given polygon is a rectangle.
The area of a rectangle is
Where l is length and w is width.
The area of given polynomial is
Therefore the area of the polynomial is 35 square unit.
