7x - 11 = -19 + 3x
Let's first get the x isolated to one side, so subtract 3x from both sides:
4x - 11 = -19
Now add 11 to both sides:
4x = -8
Now to get x by itself, divide 4x by 4, and then divide the other side by 4, leaving:
x = -2
Check your work:
7(-2) - 11 = -19 + 3(-2)
-14 - 11 = -19 - 6
-25 = -25
Yep!

The <u>correct answer</u> is:
<span>c) Each point in the data set is near the regression line.
Explanation:
A best fit regression line is the line that most closely approximates the data. This means that the line must be near most of, if not all, of the points of the data set.
If this truly is the line of best fit, the points of the data will be near the line.</span>
<u>Answer:</u>
<u>Step-by-step explanation:</u>
<u>We know that:</u>
- x = y
- 2(70 + 60) + x + y = 360
<u>Work:</u>
- 2(130) + x + x = 360
- => 260 + 2x = 360
- => 2x = 360 - 260
- => 2x = 100
- => x = 50
Hence, <u>the value of x is 50°.</u>
Hoped this helped.
5/12 is the answer just do 15 and then add 15 + 21 to get 36 and then you reduce 15/36 and get 5/12
