Help!!!!!!!!!!!!!!!!!!!!!!!

Nataly [62]

Hello.

Firstly, let's isolate x on the equation:

$\mathsf{f(x) = 3x + 3} \\ \\ \mathsf{y = 3x + 3} \\ \\ \mathsf{-3x = -y + 3} \\ \\ \mathsf{x = \dfrac{-y + 3}{3}}$

Now, we can replace 'x' for 'y' and vice-versa:

$\mathsf{f^{-1}(x) = \frac{-x + 3}{3}`}$

Hope I helped.

Mrs. Gargantua thinks she finally may have found

docker41 [41]

Answer:

She should used 4.5 ounces of the 4% and 1.5 ounces of the 20%.

Step-by-step explanation:

x = amount of 4% fuel

6 - x = amount of 20% fuel

0.04x + 0.2(6 - x) = 0.08(6) Multiply both sides by 100 to remove the decimals

4x + 20(6 - x) = 8(6)

4x + 120 - 20x = 48

-16x + 120 = 48

-16x = -72

x = 4.5

She should used 4.5 ounces of the 4% and 1.5 ounces of the 20%.
