Step-by-step explanation:
Answer:
(5, -2)
Step-by-step explanation:
x - 7 = -2x + 8
add 2x to both sides
x - 7 + 2x = -2x + 8 + 2x
3x - 7 = 8
Add 7 to both sides
3x - 7 + 7 = 8 + 7
3x = 15
3x = 15
x = 5
y = 5 - 7
y = -2
Solution (5, -2)
This question can be found using the distance formula. This formula can be written as d=sqrt((x2-x1)2+(y2-y1)2). I’d advise looking up the formula, as mobile wont let me format the exponents. Plug in your values, and you should get d=sqrt(3481+3136). Simplify this, and you will get d=sqrt(6617).
We keep the 2x^2 because we can only subtract something from that if it also is squared. From there, we subtract the 7x from 2x^2-11. Since there is no previous x's in the 2x^2-11, we just make it -7x. So, without even continuing the problem, we see that A) is the correct answer because it is the only one with -7x.
