Use the scenario and elimination by multiplication to answer the question.
SVEN [57.7K]
Answer:
C
Explanation:
You could solve this in the elimination way that I have been done in here.

I use Jason as an example that he paid $11.84 for 5t ( tacos ) + 1q ( quesadilla )
Therefore we could do the elimination if the taco cost 3.45 x 5 = 17.25, would be over the cost.

-> Cross B answer

Then we take 1.57 x 5 = 7.85. 11.84 - 7.85 = 3.99, which it is not 3.39 => Cross D answer.

Therefore the cost of tacos need to be 1.69 because there have been a repetition in both A& C

1.69 x 5 = 8.45. $11.84 - 8.45 = $3.39 for quesadillas.

Which it proves for the answer is C

Given that f(x)= x^3/4 +6<br> a) Find f(4)<br> b) Find f^-1(x)<br> c) Find f^-1(8)
Anna35 [415]

a)

f(4)=\dfrac{4^3}{4}+6=4^2+6=16+6=22

b)

\begin{aligned}\\&y=\dfrac{x^3}{4}+6\\&4y=x^3+24\\&x^3=4y-24\\&x=\sqrt[3]{4y-24}\\&f^{-1}(x)=\sqrt[3]{4x-24}\end

c)

f^{-1}(8)=\sqrt[3]{4\cdot8-24}=\sqrt[3]{8}=2
