Fill in the blank so that the following statement is true. The first step in solving \( \frac{x-7}{x+8}=\frac{x-1}{x+4} \) is to multiply both sides by The first step in solving \( \frac{x-7}{x+8}=\frac{x-1}{x+4} \) is to multiply both sides by

Compute the difference quotient, \( \frac{f(x+h)-f(x)}{h} \), of the function \( f(x)=9 x^{3} \), and simplify the answer as much as possible. \( \frac{f(x+h)-f(x)}{h}=\square \)

A tailor cut \( 3 / 4 \) of an inch off a skirt and \( 5 / 12 \) of an inch off a pair of pants. How much more did the tailor cut off the skirt than the pants? Write your answer as a fraction or as a whole or mixed number. Submit inches

Use the graph to find the indicated value of the function. \( f(-3)=\square \)

The weight of 3 eggs is shown. Assuming the three eggs are all the same weight, find the constant of proportionality.

\( x+1 ; x^{3}+3 x^{2}+x+k\left[\right. \) Hint: Let \( f(x)=x^{3}+3 x^{2}+x+k \)
