Graph the system of equations below on a piece of paper what is the solution x+y=12 -x=-y-10

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

the answer to this is 4340

hope this if needed hmu

a) is $10.34

b) is 6 toppings

15 / 2 = 7.5

100 / 7.5 = 13.
