Last year, Kevin had 20,000 to invest. He invested some of it in an account that paid 6% simple interest per year, and he invest

tester [92]

$13,000 was invested at 6% whereas $7,000 was invested at 10% using simple interest approach

What is simple interest?

Simple interest is determined as the amount invested multiplied by the interest rate and the number of years that investment lasts.

I=PRT

I=interest

P=principal

R=rate of return

T=time

Let X be the amount invested at 6%

I at 6%=6%*X*1

I=0.06X

The amount invested at 10% is 20,000-X

total interest=0.06X+0.10*(20000-X)

total interest=1,480

1480=0.06X+0.10*(20000-X)

1480=0.06X+2000-0.10X

1480-2000=0.06X-0.10X

-520=-0.04X

X=-520/-0.04

X=13,000

13,000 was invested at 6%

amount invested at 10%=20,000-X

amount invested at 10%=20,000-13,000

amount invested at 10%=7,000

What is the slope if the line through the points 2/3, 4/7 and 2/3, 11/7

Umnica [9.8K]

The fromula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points $\left(\dfrac{2}{3},\ \dfrac{4}{7}\right)$ and $\left(\dfrac{2}{3},\ \dfrac{11}{7}\right)$

Substitute:

$m=\dfrac{\frac{11}{7}-\frac{4}{7}}{\frac{2}{3}-\frac{2}{3}}=\dfrac{\frac{7}{7}}{0}\ !!!!$

<h3>Answer: slope is undefined.</h3><h3 />

It's a vertical line: $x=\dfrac{2}{3}$
