Answer:

simplify 36 - 4.5x + 36 to -4.5x + 72

simplify 102 - 7.5x - 60 to -7.5x + 42

add 7.5x to both sides

simplify -4.5x + 72 + 7.5x to 3x + 72

subtract 72 from both sides

simplify 42 - 72 to -30

divide both sides by 3

simplify 30/3 to 10

Answer: x = -10

Again help, i don’t understand this at all
Semenov [28]

Answer:

<em>The difference quotient of f is 8. </em><em>Option C</em>

Explanation:

<u>Difference Quotient</u>

Given a function f(x), the difference quotient is defined as

\displaystyle d=\frac{f(h+h)-f(x)}{h},\ h\neq 0

The function provided in the question is

f(x)=8x+1

Find f(x+h) by substituting x by x+h:

f(x+h)=8(x+h)+1

f(x+h)=8x+8h+1

Now compute:

\displaystyle d=\frac{8x+8h+1-(8x+1)}{h}

Operating:

\displaystyle d=\frac{8x+8h+1-8x-1}{h}

Simplifying:

\displaystyle d=\frac{8h}{h}

d=8

A.  Incorrect.

This choice is different from the answer.

B. Incorrect.

This choice is different from the answer.

C. Is correct

The difference quotient is 8 as explained above.

D. Incorrect.

This choice is different from the answer.
