Step-by-step explanation:

Given the 2 equations

y = 4x - 6 → (1)

y = - 2x + 2 → (2)

Substitute y = 4x - 6 into (2)

4x - 6 = - 2x + 2 ( add 2x to both sides )

6x - 6 = 2 ( add 6 to both sides )

6x = 8 ( divide both sides by 6 )

x = =

Substitute x = into either of the 2 equations for corresponding value of y

Substituting in (1)

y = (4 × ) - 6 = - = -

Solution is (, - ) → C

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.

6 adults and 9 children went.

a + c = 15

12a + 9c = 153

12(6) + 9(9) = 153

72 + 81 = 153
