Your parents decide that they will help you out for the first two months after graduating from college by helping you buy groceries for your meals, but they won’t cover the cost of you going out to eat at restaurants or fast food. For the first month you submit your receipts, 13 receipts for fast food and four receipts for Krogers, and they totaled $487. The second month you submit receipts for six fast food meals and two purchases from Krogers, and totaled $232. The receipts do not list the per-item price. What were the average costs of one fast food meal and of one trip to Krogers? Show your work and explain your answer.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

step-by-step explanation:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)
