Answer:
In this equation, the value of x is 9.
Step-by-step explanation:
-4(6x + 3) = -12(x + 10)
Distribute -4 to (6x + 3) and distribute -12 to (x + 10).
-24x - 12 = -12x - 120
Add 12x on both sides of the equation.
-12x - 12 = -120
Add 12 on both sides of the equation.
-12x = -108
Divide -12 on both sides of the equation.
x = 9
The value of x in this equation is 9.
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
