Answer:

f(g(x))=f\left(-\dfrac{3x+21}{5}\right)=x\\\\g(f(x))=g\left(-\dfrac{5}{3}x-7\right)=x

Step-by-step explanation:

Fill in the given expressions and simplify.

f(g(x))=f\left(-\dfrac{3x+21}{5}\right)=-\dfrac{5}{3}\left(-\dfrac{3x+21}{5}\right)-7\\\\=\left(-\dfrac{5}{3}\right)\left(-\dfrac{3x}{5}\right)-\left(\dfrac{5}{3}\right)\left(-\dfrac{21}{5}\right)-7\\\\=\dfrac{15x}{15}+\dfrac{5\cdot 21}{3\cdot 5}-7=x+7-7=x

Going the other way, we have ...

g(f(x))=\displaystyle -\frac{3\left(-\frac{5}{3}x-7\right)+21}{5}=-\frac{-5x-21+21}{5}=x

Answer:

$3.75

Step-by-step explanation:

. Chocolates = $2

. Only has to spend $30

. Milk costs $4

30 divided by 2 = 15

15 divided by 4 = $3.75

To Check: 3.75 x 4 = 15

15 x 2 = $30

Explain: All you have to do is divide 30 by 2 and you will get 15. Then, divide 15 by 4 and you will get $3.75. When you check, you should use the inverse operation which is multiplication, so with that being said, 3.75 x 4 = $15.  15 x 2 = $30.

Your welcome!

Write an equation in point slope form of a line that passes through the given point and has the given slope.
maxonik [38]

the equation of a line in point-slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = - 2 and (a, b) = (2, 6), hence

y - 6 = - 2(x - 2) ← equation in point-slope form
