Step-by-step explanation:
Answer:
do you have a photo of the question
Step-by-step explanation:
Let p represent the quantity of plates
Let c represent the quantity of cups
Cook 1: 4p + 5c = 25.25
Cook 2: 7p + 3c = 25.50
Use elimination method to solve:
-3(4p + 5c = 25.25) → -12p -15c = -75.75
5(7p + 3c = 25.50) → 35p +15c = 127.50
Add the equations: 23p + 0c = 51.75
Divide by 23 to solve for p: p = 2.25
Answer: the cost of plate is $2.25
6.71*108= 724.68 then divide that by 60 to see how far it goes per minute. Which is 12.078 then multiply by 90 so 1,087.02
Slope = -2
Point-slope equation for line of slope -2 that passes through (1,8):
y-8 = -2(x-1)
Solve for y
y = -2x+10
y-intercept = 10
