Answer:
c (0,-4)
Step-by-step explanation:
-5x+y = -4
4x - 4y =16
Solve the first equation for y since we are using substitution.
-5x+y = -4
Add 5x to each side
-5x+5x+y = -4+5x
y = 5x-4
Substitute this equation y = 5x-4 into the second equation.
4x -4(5x-4) = 16
Distribute the -4
4x - 4(5x) -4(-4) = 16
4x-20x +16 = 16
Combine like terms
-16x +16 =16
Subtract 16 from each side
-16x+16-16 = 16-16
-16x =0
Divide by -16
x=0
But we still need to find y
y = 5x-4
y = 5(0) -4
y = -4

Answer:
Step-by-step explanation:
A shopper paid $2.52 for 4.5 pounds of potatoes. This means that the unit price for each potato would be
2.52/4.5 = 0.55556
Approximately $0.6 per pound.
The shopper paid $7.75 for 2.5 pounds of broccoli. This means that the unit price for each broccoli would be
7.75/2.5 = $3.1 per pound.
The shopper paid $2.45 for 2.5 pounds of pears. This means that the unit price for each pear would be
2.45/2.5 = $0.98 per pound
