I can answer the slopes
Answer:
1. would have a slope of 2
2. would have a slope of -1.66
3.would have a slope of 0
4. would have a slope of -13
Step-by-step explanation:
(Y2 - Y1) / (X2 -X1)
1. (9-5) / (4-2) = 4 / 2 =2
2. (-5-5) / (3 - -3) = -10 / 6 = 1.66
3. (2 - 2) / (5 - -4) = 0 / 9 = 0
4. (-7 - 6) / (3 - 3) = -13 / 0 = -13
12x² - 3.5y + 10y + 1.5x² + y Combine like terms
13.5x² + 7.5y
Answer:
The correct answer is 32.88.
Step-by-step explanation:
Cost price for a 26 ounce can of coffee = 6.75.
A case of coffee contains 12 cans.
Total cost price of a case is 12 × 6.75 = 81.
Selling price of each can of coffee = 9.49.
Total selling price of a case is 12 × 9.49 = 113.88.
Total profit for selling a case of cnas of coffee is given by 113.88 - 81 = 32.88
Thus the profit for selling each can is 32.88.
