Explanation:

<u>Direct Variation</u>: A <u>relationship</u> where one quantity is a constant multiplied by another quantity is called <u>direct variation</u>.

<u>Inverse Variation</u>: <u>Inverse variation</u> is defiend as the relationship between two variables in which the resultant product is a constant. If a is inversely proportional to b, the form of equation is a = k/b, where k is constant. Inverse variation is known as the opposite of direct variation. If there an increas ein one variable, the other variable decreases in proportion so that the resultant product remains unchanged.

NEED HELP ASAP
Aliun [14]
Well, first you want to figure out how many sentences Jolie has left to read. You can do that by multiplying 120 by 17 which equals 2,040. Then you have to divide 2,040 by 14. The answer to that is about 145.72 which you could just leave at about 145 minutes. And to simplify that even more you could divide by 60 and figure that 145.72 is about 2 hours and 42 minutes.

HELP PLEASE LOTS OF POINTS!!
Paladinen [302]

Answer:

<em>Thus, f and g are inverse functions</em>

Step-by-step explanation:

<u>Inverse Functions</u>

If two functions f(x) and g(x) are inverses, then it follows that:

f\circ g(x)=x

Or:

g\circ  f(x)=x

We are given

\displaystyle f(x)=\frac{1}{4}x-6

g(x)=4x+24

Let's test if they are inverse functions:

f\circ g(x)=\frac{1}{4}(4x+24)-6

Simplifying:

f\circ g(x)=x+6-6=x

Now find:

\displaystyle g\circ f(x)=4\left(\frac{1}{4}x-6\right)+24

Operating:

\displaystyle g\circ f(x)=x-24+24=x

Thus, f and g are inverse functions
