I just need the answers to these and I'll be done with my homework.Please help

Answer 1

Explanation:

Answer 2

`3) x = 12, \ y = (x)/(3) = (12)/(3) = 4`

`4) x = 2 , \ y = 5x + 9 = ( 5 * 2 ) + 9 = 10 + 9 = 19`

`5. a ) Profit = Cost \ Price - Selling\ Price`

Profit = P, Cost C,

`P = 0.50C - 75`

`b) Break \ even\ means \ zero \ profit`

`P = 0.50C - 75 \\\\0 = 0.50C - 75\\\\0.50C = 75\\\\C = (75)/(0.50) = 150`

Number of cups to break even is 150 cups.
