Basically (g of f)x=(f(g(x)) so
g of f=f(g(x))=7(5x^2+4x-3)+5
distribute
f(g(x))=35x^2+28x-21+5=35x^2+28x-16

g of f=35x^2+28x-16

Find the equation of the line passes through (-3,-4) and whose slope is 3/2 in slope intercept form. (Algebra 2 or Geometry)
ioda

Hey there! I'm happy to help!

Slope intercept form is y=mx+b, where m is the slope and b is the y-intercept. We already have the slope, so our equation so far is y=3/2x+b. We just need to find the b for it to be complete.

To do this, we plug in a point on the line and solve for b. We have a point (-3,-4), so let's use it and solve.

-4=3/2(-3)+b

Undo parentheses.

-4=-9/2+b

Add 9/2 to both sides

b=1/2

Therefore, our equation is y=3/2x+1/2.

Have a wonderful day! :D

Assume that all interest is simple interestBerger Car rental borrow $8500 at 4% interest to cover the increase cost of the auto
viva [34]

we know that

The formula of simple interest is equal to

I=P(rt)

In this problem

we have

I=$170

P=$8,500

r=4%=4/100=0.04

t=?

substitute given values in the formula

\begin{gathered} 170=8,500(0.04t) \\ Solve\text{ for t} \\ t=\frac{170}{8,500*0.04} \\ t=0.5\text{ years} \end{gathered}

therefore

0.5 years=6 months

<h2>The answer is 6 months</h2>

5. Enter the answer as a decimal
Hitman42 [59]

Answer:

6.5%

Step-by-step explanation:

I = prt

5616 = 7200 × r × 12

r = 5616/(7200 × 12)

r = 0.065

r = 6.5%
