Answer:
y=(x+4)^2 is shifted four units to the left.
Step-by-step explanation:
When you think of this transformation you have to know that the parabola isn't changed and only the units do in this situation.
8p-8=-9(2p+5)-9(6-3p)
p=91
I showed the work up there and checked
Set x as Joe's (current) age, and y as Mary's age (current). We can start building equations; x = y - 2 + 10, or x = y + 8. Now, from the second statement, x - 2 = 2(y - 2). Substituting, we obtain y = 10, and x = 18.
