Answer:
(-5, 3)
Step-by-step explanation:
Elimination seems like the best method to use here.
x+y=-2
x-y=-8
---------
2x=-10
Divide everything by two
x=-5
Now plug it back into one of the original equations,
-5+y=-2
Add 5 to everything
y=3
Factor the expression
Use the properties of radicals
Simplify the roots
Calculate
And your solution will be 20 overall 5

Answer - 11
I’m assuming you’re trying to find the line AB (basically the distance between point A and B). If that’s the case, since they both have the same x vale, subtract their y values. 14-3 gives you 11, which is the length of line AB
To work out the estimate cost you need do 200 * 5=$1000
then I used a calculator and the actual answer is $895
