Step-by-step explanation:
(2x³y^-4)^-2 = 1/(4x⁶y^‐8) = y⁸/(4x⁶)
1/(8x⁵y^-7) = y⁷/(8x⁵)
4x^-9y⁴ = 4y⁴/x⁹
so, the whole expression is then
y⁸/(4x⁶) × y⁷/(8x⁵) × 4y⁴/x⁹
4y¹⁹/(32x²⁰) = y¹⁹/(8x²⁰)
so, D is the correct answer.
Answer:
G.
Step-by-step explanation:
Graph shows constant change between the weight and the cost.
3/2.25 is 1.33333333
4/3 is 1.3333333
5/3.75 is 1.3333333 as well.
Others are not constant.
Answer:
90 hours
Step-by-step explanation:
- 67 + 6 + 9 + 8 = 90 hours
(11+21)-(3-101)=(11+21-3-10=(11-3)+(21-101=8-18=53
Answer:
B, C, and D
Step-by-step explanation:
First, we have to simplify 9 and 6 down to 3 and 2
After you just see which one works and which one doesn't.
