Answer:
<h3>Each of the given pairs is not a solution to the given equation.</h3>
Step-by-step explanation:
Put the x and y values in the equation 4y = -7x + 5 and check the equality of the left and right side of the equation.
A. x = -5 and y = 0
L = 4(0) = 0
R = -7(-5) + 5 = 35 + 5 = 40
L ≠ R
B. x = -3 and y = 4
L = 4(4) = 16
R = -7(-3) + 5 = 21 + 5 = 26
L ≠ R
C. x = 1 and y = 3
L = 4(3) = 12
R = -7(1) + 5 = -7 + 5 = -2
L ≠ R
D. x = 2 and y = -2
L = 4(-2) = -8
R = -7(2) + 5 = -14 + 5 = -9

Good luck!
Answer:
x= -42
Step-by-step explanation:
put the liketerms together
x+35= -7
x=-35-7
note*the operation sign changes after crossing the equal sign
x= -42
I always do things differently than I am taught, so here is how I do it...I divide 120 by 100, then I multiply it by 80(because you are finding 80%) I got 96,
Another way to do it is... Divide .8 by 120, the answer is also 96.
Good Luck! Hope I helped:)
Answer:
(2, - 5)
Explanation:
The line y = -1 is horizontal: parallel to the y-axis.
The point B (2,3) is above the line y = - 1 at a distance equal to the y-coordinate of B (y = 3) less - 1:
Δy = 3 - ( - 1) = 4
When the point B (2,3) is reflected over the line y = -1, the x-coordinate does not change. The image will be 4 units down the line y = -1, thus the y-coordinate will be - 1 - 4 = - 5.
Hence, the coordinates of the vertex B' are x = 2, y = - 5: (2, - 5).
