I think it would be y=-1(x)+1

Answer: y = -3/2x + 2
Solution: -1 - 5= -6
2-(-2)=4 slope is:-6/4 which is simplified to -3/2.
Y intercept: y=mx+b
Choose a coordinate. I chose(2,-1).
-1=-3/4x × 2 + b
-1= -3 + b
2=b(so 2 is the y intercept)
Equation: y=-3/4x + 2

Find the measure of each interior angle of a regular octagon. (A regular polygon is one that has all the same sides and angles).

NemiM [27]

The interior angle of a regular octagon is 135 degrees.

<h3>What is an octagon?</h3>

An octagon is a polygon that has 8 sides. Therefore, a regular octagon is a octagon with all it sides and angles equal to each other.

Therefore, the sum of angles in an octagon is each interior angle multiply by the number of sides.

Therefore,

n = number of sides = 8

Hence,

interior angle = (n - 2)180 / n

interior angle = (8 - 2)180 / 8

interior angle = 6 × 180 / 8

interior angle = 1080 / 8 = 135°

Answer:

$V = 1847.26\ ft^3$

Step-by-step explanation:

Step 1: Determine the volume

$V=\pi r^2h$

$V = \pi *(7\ ft)^2 * (12\ ft)$

$V = \pi *49\ ft^2 * 12\ ft$

$V = \pi * 588\ ft^3$

$V = 1847.26\ ft^3$

Answer: $V = 1847.26\ ft^3$

Joel earns a commission of 5% on the audio equipment he sells , and the store keeps the rest . He sells a $750 amplifier. A. How

den301095 [7]

Answer:

Joel earns $35.00 commission and the store keeps $715.

Step-by-step explanation:

You need to figure 5% of what he sold - or 5% of $750.

Of course, you can use a calculator, or multiply $750 by .05. I prefer to think of 10 percent ($75.00) and half that to get 5%. $35.00.

Joel earns $35.00 on the sale. Not bad!

If he gets to keep $35, deduct this from the price to find out how much the store will keep.

$750 - $35 - $715.
