Question

Please help

Answer 1

1) What is the domain if the range is 66.  Range is "y" so substitute 66 for y and solve for x.

10.5x + 3 = 66     solve for x.  You should get x = 6

2) What is the range if the domain is 9.  Domain is "x" so substitute 9 for x and solve for y

10.5(9) + 3 = y.  You should get y = 97.5
