Answer:
scale = ½
center = (2, -5)
Step-by-step explanation:
The distance between A and B is 8
The distance between A' and B is 4
therefore the dilation scale factor is 4/8 = ½
As B and B' have the same x value, the center must also have the same x value of 2
The y value for A is -1
The y value for A' is -3
IF the y value for the center is Y
½(Y - (-1)) = (Y -(-3))
½(Y + 1) = (Y + 3)
½Y + ½ = Y + 3
-2.5 = ½Y
Y = -5
-22
From the graph, f(-8) = -2 and g(2) = -4, so the answer will be -3 * (-2) + 7 * (-4) = 6 - 28 = -22. Hope this helps!
