Answer:
40
Step-by-step explanation:
To find the maximum we need to find the vertex. We can do this by writing the equation in vertex notation by completing the square.
A(w) = -w(w - 80)
= -w² + 80w
= -(w² - 80w) = -(w - 40)² + 160
The vertex is then (40, 160) and since we are looking for the value of w it will be 40.
y-2=3/2 (x+1) must be first
45°. I’m not sure what the relationship is but I think it’s linear pair ?
So lets say you have 10+2y=2x, first you subract 10 by both sides, now you got 2y=2x-10. Divide all the numbers by 2, and then you got y=x-5.
