8 maple donuts
11 chocolate donuts
19 donuts total, where there are 3 fewer maple donuts than chocolate donuts. (11-3=8).
Answer:
Please see below :)
Step-by-step explanation:
y - 5 = -(x + 11) + 2
y - 5 = -x - 11 + 2
y = -x - 11 + 2 + 5
y = -x - 9 + 5
y = -x - 4
54x + 15 = -3(3y + 1)
54x + 15 = -9y - 3
54x + 15 + 3 = -9y
54x + 18 = -9y
-6x - 2 = y
y = -6x - 2
Please let me know if I've done anything wrong!
x = 8, --- 12
I hope this helped :))))))))))))))))))
Answer:
Step-by-step explanation:
The function is f(x) = -4x²+10x-8
Let Δ be our the dicriminant
- Δ= b²-4ac
- b = 10
- a = -4
- c = -8
- Δ = 10²-4*(-4)(-8)
- Δ = 100-128
- Δ = -28
The value of the discriminant is -28 and since it is negative this function has no real zeroes
Answer:
Quinzel sold 17 pairs of shoes last month.
Step-by-step explanation:
Let be "Q" the number of pairs of shoes Quinzel sold last month and "J" the number of pairs of shoes Joseph sold last month.
Set up a system of equations:
![\left \{ {{Q=J-18} \atop {Q+J=52} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7B%7BQ%3DJ-18%7D%20%5Catop%20%7BQ%2BJ%3D52%7D%20%5Cright.)
Solve for "J" from the first equation:
![J=Q+18](https://tex.z-dn.net/?f=J%3DQ%2B18)
Applying the Substitution Method, you get:
![Q+J=52\\\\Q+(Q+18)=52\\\\2Q=52-18\\\\Q=\frac{34}{2} \\\\Q=17](https://tex.z-dn.net/?f=Q%2BJ%3D52%5C%5C%5C%5CQ%2B%28Q%2B18%29%3D52%5C%5C%5C%5C2Q%3D52-18%5C%5C%5C%5CQ%3D%5Cfrac%7B34%7D%7B2%7D%20%5C%5C%5C%5CQ%3D17)
