Answer:
2 hours or lower
Step-by-step explanation:
$13 + $5t = fee
13 + 15t = 43 --> minus 13 on both sides
15t = 30 --> divide by 15 on both sides
t = 2

Answer:
put 1 orange in each group and then cut the last in thirds and each group will have 1 and 1/3 oranges
Step-by-step explanation:
Inverting a function is equivalent to solve the equation x = f(y) for the variable y.
Take the function:
y = ∛(x – 2) + 6
Switch x and y, and then solve the equation for y:
x = ∛(y – 2) + 6
x – 6 = ∛(y – 2)
∛(y – 2) = x – 6
Cube both sides:
[ ∛(y – 2) ]³ = (x – 6)³
y – 2 = (x – 6)³
y = (x – 6)³ + 2 <——— and there it is, the inverse function.
I hope this helps. =)
