Jerome currently has an account balance of $1,859.55. His initial deposit on the account was $825 and it earned 5.7% simple inte

zepelin [54]

Answer:

22 years

Step-by-step explanation:

Well we know the formula for simple interest is

I = PRT

I = interest earned

P = initial balance

R = rate

T = time

We want to solve for time here....so rearrange for T

T= I/(PR )

We have

P = 825

R = .057

And I = current balance - initial balance = 1859.55 - 825 = 1034.55

So plugging all those in we have

T = 1034.55/(825×.057 )

T = 1034.55/47.025

T = 22

It was held for 22 years.

Determine the slope of the line that passes though the points (2,-5) and (4,3).

schepotkina [342]

Answer: slope = 2

Step-by-step explanation:

The formula for calculating slope is given as :

$m = \frac{y_{2}-y_{1}}{x_{2}-x_{1} }$

$x_{1}=2$

$x_{2}=4$

$y_{1}=-5$

$y_{2}=3$

substituting into the formula , we have :

$m = \frac{3-(-5)}{4-2}$

$m = \frac{8}{2}$

$m = 2$

Therefore : slope = 2
