Answer:
(-18, 2)
Step-by-step explanation:
To rotate a point by 90°:
R₉₀ (x, y) = (-y, x)
R₉₀ (1, 9) = (-9, 1)
To dilate by 2:
D₂ (x, y) = (2x, 2y)
D₂ (-9, 1) = (-18, 2)
Answer:
Kims savings will be $60.
Step-by-step explanation:
120 * .50 = 60
-7(x^2 - 6) + 2y
x = 2 and y= -6
Plug in the numbers and solve
-7(2^2-6) + 2(-6)
-7(4 - 6) + -12
-7(-2) - 12
14 - 12
