(p^2 - 5p + 4) - (4p^2 - 9p + 11)
= p^2 - 5p + 4 - 4p^2 + 9p - 11
= p^2 - 4p^2 -5p + 9p + 4 - 11
= -3p^2 + 4p - 7
Answer:
9
Step-by-step explanation:
if the opposition of a number is equal to -9.
hence the expression above....
Answer:
y = 12/5x + 22
Step-by-step explanation:
First, let's find the slope of the AB line.
y2 - y1 / x2 - x1
3 - 8 / 2 - (-10)
-5 / 12
= -5/12
When a line is perpendicular to something, the slope becomes the opposite.
y = 12/5x + b
10 = 12/5(-5) + b
10 = -12 + b
22 = b
