The relative are fraction is
1. yes
2.yes
3. no
4.yes
(-1, 0)
As you can see, they're clearly intersecting at that point, which means that the solution is that point.
X = amount of 90% alloy
y = amount of 70% alloy
x + y = 60
0.9x + 0.7y = 0.85*60
0.9x + 0.7(60 - x) = 0.85*60
(0.9 - 0.7)x = (0.85 - 0.7)*60
x = (0.85 - 0.7)*60/(0.9 - 0.7)
x = 45 ounces
y = 60 - 45
y = 15 ounces
Answer:
Step-by-step explanation:
-8x³y²(x²-4y) = -8x³y²x² + 8x³y²4y
= -8x³⁺⁵y² + 32x³y²⁺¹
= -8x⁸y² + 32x³y³
