To multiply fractions you just multiply straight across for number 5 you would do 4 times 5 which equals 20 that wild be the top number of the fraction. Then 15 times 8 is 120 so that would be the the denominator in the fraction. So it would be 20/120. If you need to simplify the fraction it would be 1/6.
Answer:
let g be f(x)
g= <u>4</u><u>x</u><u> </u><u>-</u><u>3</u>
. 7
make x the subject
<u>7</u><u>g</u><u> </u><u>+</u><u>3</u><u>. </u> =x
4
the inverse function of f(x) = <u>7</u><u>x</u><u>+</u><u>3</u>

2 4/9 is the correct answer*
10 is the missing number.
