Answer:
D
Step-by-step explanation:
9x+(5y+x)-3y
Remove the parenthesis
When there is a "+" in front of an expression in parentheses, the expression remains the same
9x+5y+x-3y
Collect like terms
(9x+x)+(5y-3y)
10x+2y
Answer:
C and D
Step-by-step explanation:
Let's add this all together.
9x + 5y + x - 3y
Combine like terms 5y + -3y and 9x + x
10x + 2y
So we know D is at least correct.
What else? C is also correct, because we can expand it outward.
10x + 5y - 3y = 10x + 2y
A and B are not correct! We can't multiply the ys or the xs.

Answer:
y+10 = 2(x+1)
Step-by-step explanation:
We have two points so we can find the slope
(−1,−10) and (5,2)
m = (y2-y1)/(x2-x1)
= (2- -10)/(5 - -1)
= (2+10)/(5+1)
= 12/6
=2
The point slope form is
y-y1 = m(x-x1)
y - -10 = 2(x--1)
y+10 = 2(x+1)
If we use the other point
y -2 = 2(x-5)
Mean (average) - 13027.2
Median (middle number) - 12,200
Mode (occurs the most often) - none of the numbers occur more than once?
Mean would be the best to predict because it is the average miles Gina has driven over the past five years
