Answer:

5x+17

Step-by-step explanation:

1.) distribute/multiply the 2 into (x+7) and you get 2x+14

2.) then do the same with the 3 into (x+1) and you get 3x+3

3.) finally, just combine the like terms which are 3x and 2x (just add them), and 14 and 3 (again add them) and your final answer should be 5x+17

Y=x+2 y=-3X <br><br>solve system of equations algebraically <br>​
goblinko [34]

Answer:

(x,y) = -1/2 , 3/2

Step-by-step explanation:

Let y = x +2 ----- (1)

y = -3x ------ (2)

Put equal both sides x +2 = -3x

x = -3x -2

x +3x = -2

4x = -2

x = -1/2 Put it in 2nd equation

Y = -3 (-1/2)

y = 3/2

so (x,y) = -1/2 , 3/2

Hope you got it.

Hese are the values in Paul’s data set.
andrew-mc [135]
Answer: See description below.

The residuals are the differences between the predicted values and the actual values. You will need to make a scatter plot of each difference.

Here are the five points that you will need to plot:
20 - 21 = -1  (1, -1)
17 - 16 = 1 (2, 1)
9 - 10 = -1 (4, -1)
6 - 5 = 1 (5, 1)
2 - 2 = 0 (6, 0)
