Answer:
y = 6.
Step-by-step explanation:
z = kx/y
9 = k*24/8
24k = 72
k = 3.
So z = 3x/y
When x = 10 and z = 5
5 = 3*10/y
5y = 30
y = 6.
Answer:
3 hours
Step-by-step explanation:
D=4H+35
47=4H+35
47-35=4H
12=4H
H=3
For this case we must find the inverse of the following function:

To do this, we follow the steps below:
We exchange the variables:

We clear the variable "x" (the variable is already cleared):

We change "x" to "y":

We change y for
:

Answer:
B
Step-by-step explanation:
logₓ 7 = 3
x³ = 7
Take cube root both sides
