So first you have x, number of hot dogs, and y, the number of hamburgers. You need to add x to y to find 230, which is the total amount of hot dogs and hamburgers sold. Then you add 0.50x to 0.75y, which equals $138.50
Your answer is x + y = 230 and 0.50x + 075y = 138.50.
(4, 2) and (4, -5)
(Look at the photo. They have the same x-coordinates, but different y-coordinates; one is positive the other is negative, resuting in different quadrants)
I hope this helps!

Answer:
Step-by-step explanation:
This is segment addition in Geometry. Picture a straight line with endpoints A and C. B is a point stuck somewhere between them. The length of AC then is equal to the length of AB plus the length of BC. In algebraic terms:
AC = AB + BC. Filling in from the problem:
81 = 2x + 1 + 6x and combine like terms:
81 = 8x + 1 and subtract over the 1:
80 = 8x and divide by 8 to find
x = 10.
