AlexFokin [52]

Answer:

≈ $9164.35

Step-by-step explanation:

The future amount A is calculated as

A = P (1+\frac{r}{n}) ^{nt}

P is the Principle

r is interest rate

n is number of times per year compounding happens

t is the number of years

Here P = 15000 , r = 16% = 0.16, n = 12 , t = 3

A = 15000 (1+\frac{0.16}{12}) ^{(12(3))}

   = 15000 ((1.01333)^{36}

   ≈ 24164.35

Interest paid = $24164.35 - $15000 = $9164.35

What is the equation of the line that is parallel to 3x-5y=7 and passes through the point (-10,8)
Goryan [66]

Answer:

5y - 3x = 70

Step-by-step explanation:

The given line has equation:

3x-5y=7

We need to determine the slope of this line, so we rewrite in slope intercept form.

y =  \frac{3}{5}x -  \frac{7}{5}

The slope of this line , when we compare to y=mx+c is

m =  \frac{3}{5}

All parallel lines have the same slope.

Hence our line also has the same slope

This line passes through (-10,8).

The equation is given by:

y-y_1=m(x-x_1)

We substitute the slope and point to get:

y - 8 =  \frac{3}{5}(x -  - 10)

We expand to get:

y - 8 =  \frac{3}{5}x  + 6

y =  \frac{3}{5}x  + 14

5y - 3x = 70
