The value of x in D o,k (x,9) -> (-10,-6) is (d) 15
How to determine the value of x?
The dilation rule is given as:
D o,k (x,9) -> (-10,-6)
Write out the coordinates
(x,9) -> (-10,-6)
Express as fraction
x/9 = -10/-6
Multiply both sides by 9
x = -9 * 10/-6
Evaluate the product
x = 15
Hence, the value of x in D o,k (x,9) -> (-10,-6) is (d) 15
