Answer:
y=-2.4y
Step-by-step explanation:
First you want to restate the problem.
-3(y+3)=2y+3
Now distribute the negative.
-3y-9=2y+3
Add 3y to both sides.
-9=5y+3
Subtract 3 from both sides.
-12=5y
And solve.
-2.4=y
Answer:
x=10
Step-by-step explanation:
h(x)=-5(x-4)^2+180
Set y = 0 to find when it hits the ground
0 = -5(x-4)^2+180
Subtract 180 from each side
-180 =-5(x-4)^2+180-180
-180 =-5(x-4)^2
Divide by -5
-180/-5 =-5/-5(x-4)^2
36 = (x-4)^2
Take the square root of each side
±sqrt(36) = sqrt( (x-4)^2)
±6 = (x-4)
Add 4 to each side
4±6 = (x-4)+4
4±6=x
x = 10 or -2
But time cannot be negative so x=10
