Answer:

y=-1/5x-3.8

The y-intercept is (0,-3.8) and then the next pint would be one unit down and five units to the right. Or just plug in numbers to get your points.

Explanation:

Use the slope-point formula

y-y1=m(x-x1)

y-(-4)=(-1/5)(x-1)

y+4=-1/5x+1/5

y=-1/5x-3.8

Please help me figure out this problem

tiny-mole [99]

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 ...

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

Since the triangles are similar, they will have proportional sides. With this knowledge, we can make the proportion $\frac{8}{10} =\frac{x}{5}$ to solve for x.

Firstly, cross multiply: $40=10x$

Next, divide by 10 on both sides, and your answer will be 4 = x, or the first option.
