20x-4y=-28 helps plszz

Mathematics

In order to isolate y you would first subtract 20x from the left side and move it to the the right side.
1. -4y=-20x - 28
Then divide every number in the equation by 4 to isolate y once again.
2. Y= 5x + 7
Since negatives are being divided by negatives they become positive

What is the average of 3/8 + 2/4 + 5/8 + 7/8 + 1 1/8 + 1 5/8 + 1 7/8 + 4
melisa1 [442]

Answer:

1 3/8

Step-by-step explanation:

Well to find the average or the mean we need to add all the numbers,

3/8 + 2/4 + 5/8 + 7/8 + 1 1/8 + 1 5/8 + 1 7/8 + 4

= 11

Then we divide t by the number of numbers in the set.

11 ÷ 8 = 1 3/8

<em>Thus,</em>

<em>the average in the set is 1 3/8.</em>

<em />

<em>Hope this helps :)</em>

Slope= 5 and passes through (-2,0) in slope-intercept form
lilavasa [31]

The slope-intercept form:

y=mx+b

m - slope

b - y-intercept

We have the slope m = 5 → y=5x+b

and point (-2, 0). Substitute:

0=-2(5)+b

0=-10+b       <em>add 10 to both sides</em>

10=b\to b=10

<h3>Answer: y = 5x + 10</h3>
