Answer:
Maggie's ballon is 12 high.
Step-by-step explanation:
We are asked to find the y-value, and the x-value is given:
Plug the values in to solve for y.
y = -(2)^2 + 17(2) - 42 y
= -(4) + 34 - 42 y
= -4 + 34 - 42 y
= -12
The negative sign tells the direction. It is negative because the ballon is in the opposite direction.
