Question

point A (4,-5 is reflected across the y-axis to point B. point B is reflected across the x-axis to point C. What are the coordinates of point C

Answer 1

38.5

Explanation:

Lets say, first number = x

Second number = 3x+7

Total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 38.5

Hope this helps!!
