Q1
Answer:

Step-by-step explanation:

explanation for second step:
you divide each side by 3 to get rid of the '3' in '3x'
Answer:
h(x)
Step-by-step explanation:
to solve for an inverse, you swap the x and the y and then solve for y
f(x) = 4x^3-8
y = 4x^3 - 8
x = 4y^3 - 8 swap the x and y
now solve for y:
x + 8 = 4y^3
(x + 8)/4 = y^3
1/4x + 8/4 = y^3
1/4x + 2 = y^3
y = ![\sqrt[3]{1/4x + 2}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B1%2F4x%20%2B%202%7D)
8x+9-4x=25
4x+9=25
4x+9-9=25-9
4x=16
4x/4=16/4
X=4
Step-by-step explanation:
I don't know the answer to that.
Answer:
25.2 pints of blue paint
Step-by-step explanation:
If 8.4 is 1/4 of the total amount of paint then multiply it by 4 to find the total amount of paint, which is 33.6. The subtract 8.4 from 33.6 which is 25.2
Hope this helps :)
