to get the equation of any straight line, we simply need two points off of it, let's use those two points in the picture below.
keeping in mind that for the point-slope form, either point will do, in this case we used the second one, but the first one would have worked just the same.
Same as the last one ! Review your parallel lines, and you'll see that angles A and B have to be equal. So you solve it EXACTLY the same way as the last one.
You say "A equals B", and that means that
8x - 10 = 3x + 90
Solve that to find x (it's 20),
and then use x to find angle B (it's 150; they both are).
(Don't just take my word for it. Please work it through.)
Answer:
A.
Step-by-step explanation:
the correct answer is A. y=|x-2|+3.

No she can't spend $4.39 for each sandwich because if you divide 20 by 5 your quotient will be 4.
The answer is -40 but I don't remember how to calculate that, sorry.
