3x + 9 + 4x + x simplifies to 8x + 9
y = mx + b: m is slope, b is y-intercept
no solutions: 8x + 8
(no solution from same slope and different y-intercept)
one solution: 4x + 1
(different slope needed)
infinitely many: 8x + 9
(same y-intercept, same slope_
Rachel could get 8 ounce of cheese
Step-by-step explanation:
Step 1:
Let Rachel will pay $0.36 per ounce for cheese.
In option A, for 8 oz of cheese, it is $ 2.88.

For example, we can write, 
Answer: There were 350 hamburgers sold.
Step-by-step explanation:
x + (x +73)= 773 where x is the number of hamburgers sold and (x+ 73) is the number of cheese burgers sold.
x + (x+ 73)=773
2x + 73 = 773
2x + 700
x= 350
1(350)= 350
