Answer:

y=4x-11 . This is a linear equation, since you have the slope and y-intercept.

Step-by-step explanation:

Using the slope intercept form equation, y=mx+b. 'm' = slope, or \frac{y1-y2}{x1-x2} =

(-3-5)/(2-4) = 4.

Plug the slope in, and you'll find the value for 'b' (It's -11).

Melissa Costouras obtains a $3,000 loan for darkroom equipment. She makes six monthly payments of $511.18. Determine the APR.
nasty-shy [4]

Using the simple interest formula, it is found that the APR for the loan is of 4.472%.

<h3>What is the simple interest formula and when it is used?</h3>

Simple interest is used when there is a single compounding per time period.

The amount of money after t years in is modeled by:

A(t) = A(0)(1 + rt)

In which:

  • A(0) is the initial amount.
  • r is the interest rate, as a decimal.

The parameters for this problem are:

A(t) = 6 x 511.18 = 3067.08, A(0) = 3000, t = 0.5.

We solve the equation for r to find the APR.

A(t) = A(0)(1 + rt)

3067.08 = 3000(1 + 0.5r)

1 + 0.5r = \frac{3067.08}{3000}

1 + 0.5r = 1.02236

r = (1.02236 - 1)/0.5

r = 0.04472.

8(3n + 5) = -32<br> what does n =
olga_2 [115]

Answer: n = -3

Step-by-step explanation:

8(3n + 5) = -32

  • <em>Divide both sides by 8.</em>

(3n + 5) = -4

  • <em>Subtract 5 by both sides.</em>

3n = -4 - 5

3n = -9

  • <em>Divide both sides by 3.</em>

n = -3
