You can use the distributive property by multiplying 4 by x and 3. Then by multiplying -5 times x and -5 times 1.

f(h(x))= 2x -21

Step-by-step explanation:

f(x)= x^3 - 6

h(x)=\sqrt[3]{2x-15}

WE need to find f(h(x)), use composition of functions

Plug in h(x)

f(h(x))=f(\sqrt[3]{2x-15})

Now we plug in f(x) in f(x)

f(h(x))=f(\sqrt[3]{2x-15})=(\sqrt[3]{2x-15})^3 - 6

cube and cube root will get cancelled

f(h(x))= 2x-15 -6= 2 x-21

avanturin [10]
We add them up to find the total distance :

\dfrac{4}{10} +  \dfrac{4}{10}  =  \dfrac{8}{10}  =  \dfrac{4 \times 2}{5 \times 2}  =  \dfrac{4}{5}

\text {She walked }  \dfrac{4}{5}  \text { miles}

Can someone please help me with 7 and 8
myrzilka [38]
7) So when x=6 then z=72, they are directly proportional, so if I multiply the first with a number, then I have to multiply the second with the same number.
6 becomes 13 (x)  /multiplied with about 2.167/
72 becomes 156(y) /multiplied with about 2.167/

8) Inversely proportional, so if I multiply the first with a number, then I have to divide the second with the same number.
6 becomes 13 (x)
2 becomes ~0.92307(y) /round it to the thousandths place and you get 0.923/
