Answer:
Step-by-step explanation:
6) Slope = 5
(5 , 40) ; m =5
y - y1 = m(x -x1)
y - 40 = 5 (x - 5)
y -40 = 5x - 25
y = 5x - 25 + 40
y = 5x + 15
7) slope = 2
m =2 ; (-2 , 0)
y - y1 = m(x -x1)
y - 0 = 2(x -[-2])
y = 2(x +2)
y = 2x +4
8) D) It takes 6 miles to travel a mile
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.
