Distribute the

And combine the s terms and you should be able to solve it
It is a function. It passes the vertical line test, meaning for each x there's at most one y.
When x=2 we see y=-3 as (2,-3) is a point on the graph
I think i may know what your asking, is it a angle at a point? I don’t know what your asking so that a guess based off what i know from your question.
Answer: AC = 98
Step-by-step explanation:
A midpoint is a point on a line segment that divides it into <em>two equal parts</em>.
This means AB = BC
AB = 8x - 7
BC = 6x + 7
AB = BC
8x - 7 = 6x + 7
Solve this to find x
Add 7 to both sides
8x = 6x + 14
Subtract 6x from both sides
2x = 14
Divide both sides by 2
x = 7
Now AC = AB + BC
AC = AB + BC
AC = 8x - 7 + 6x + 7
AC = 14x
Substitute 7 for x
AC = 14(7)
AC = 98
Hope this helps!
