What is the x-coordinate of point B after it has been reflection over the x-axis and then rotated 90 degrees counterclockwise about the origin? A -1 в. 1 C -3 D 3​

Since the reflection applied is going to be over the x-axis, that means negating the y-value. As a result, points of the image are going to be: By counting the units, we know that point A is located two units above the x-axis. Count two units below the x-axis and there is point A’. Do the same for the other points and the points are also

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
