Answer:
A
Step-by-step explanation:
Because the only step is to subtract 9 from both sides and then you get x=12

Answer:
nth term: n+6
Step-by-step explanation:
a1 gives -7 and a2 gives -1. Let's compare these two numbers. From -7 to -1, we need a +6. Since -7 + 6 = -1.
a2 to a3, -1 + 6 = 5
a3 to a4, -5 + 6 = 11
Answer:
-7/8, or in decimal form: -0.875
Step-by-step explanation:
Hope this helps
43.)
a. There is an s amount of shoes, because s is the total amount of shoes
b. x is the number of shoes, so x - 1/2 = s
44.)
2s + 7 = x
45.)
the variable s is the total amount of shoes Pete has and 8 don't fit him anymore (or got ruined) so he threw them away... x - 8
46.)
The expressions y + 4 and 1y + 4 are equivalent, because a variable always has a hidden (1) next to it like (1)y and any positive number multiplied by 1 always stays the same.
I hope i helped : )
Your Welcome
Find x-intercept and y-intercept then you can draw the graph.
For example, the first question.
To find the y-intercept, x = 0
So substitute x = 0 in the equation.
[Note]: You don't need to find the y-intercept, because from, 
a is slope and b is y-intercept, you know b then you know y-intercept. For example b = 2 then y-intercept is at 2.
To find the x-intercept, y = 0
Therefore, y-intercept = 2 and x-intercept = 2/3
(Try do another problems, just do the same. When you want to find the y-intercept, just look at the value of b or substitute x = 0 and When you want to find the x-intercept, just substitute y = 0 then solve for x.)
