Lets say the cost of her haircut is $x. This makes the cost of her perm 2x (twice as much). If lunch ($5), the perm ($2x) and the haircut ($x) cost, in total, $50, we can say:
50 = 5 + 2x + x
Combine like terms:
50 = 5 + 3x
Subtract 5 from both sides to isolate 3x
50 - 5 = 3x
45 = 3x
Divide all by 3 to isolate x
x = 45/3
x = 15
So the haircut is $15 and the perm is $30 (2*$15).

Answer:
h₁(t) = -16t² +110
Step-by-step explanation:
Put the given initial height into the given formula. That will give the requested function. If the function name is supposed to be h₁(t), then rename it.
f(t) = -16t² +110 . . . . . . h = 110, the initial height
h₁(t) = -16t² +110

Answer:
(-7,-14)
Step-by-step explanation:
Going left is adding a negative value, so it would be -6-1 which is -7 for the x value and going down 5 units is also a negative value so it would be -9-5 which is -14 giving you (-7,-14)
