Answer:
A cup of yogurt has 175 calories.
Step-by-step explanation:
We can solve for the amount of calories in one cup of yogurt and in one banana by setting up and solving a system of equations. Given the information in the problem '2 cups of yogurt and 3 bananas is 650 calories' and '4 cups of yogurt and 2 bananas is 900 calories' we can set up two equations:
2y + 3b = 650 and 4y + 2b = 900, where 'y' is the cups of yogurt and 'b' is the number of bananas.
Using elimination, we can multiply the first equation by a factor of '-2' and then add the equations together to solve for the remaining variable:
-2(2y + 3b = 650) = -4y - 6b = -1300
-4y - 6b = -1300
<u>+ 4y + 2b = 900</u>
-4b = -400, or b = 100, so each banana has 100 calories, if each banana has 100 calories: 4y + 2(100) = 900 or 4y = 700 or y = 175. So, each cup of yogurt has 175 calories.

Answer:
The answer is 23
Step-by-step explanation:
x²- 3xy + 5y², for x = 3 and y = -1
(3)²- 3(3)(-1) + 5(-1)²
9 + 9 + 5 = 23
Thus, The answer is 23
