Answer:
Step-by-step explanation:
1. 12
2. 12/3.5 = 3.43
3. 12/15 = 0.8
4. 3.43/0.8
5. 315/x
6. 315/x = 0.8/3.43
7. (315)(3.43) = 0.8x divide both sides by 0.8, so x = 1,350.5625 feet.
X=3, y=4
x=-2, y=9
Set x equal to anything, then isolate y to get the other number.

Use Multiplication Distribute Property: (xy)^a = x^ay^a
6^2(x^-2)^2(0.5x)^4
Simplify 6^2 to 36
36(x^-2)^2(0.5x)^4
Use this rule: (x^a)^b = x^ab
36x^-4(0.5x)^4
Use the Negative Power Rule: x^-a = 1/x^a
36 × 1/x^4(0.5x)^4
Use the Multiplication Distributive Property: (xy)^a = x^ay^a
36 × 1/x^4 × 0.5^4x^4
Simplify 0.5^4 to 0.0625
36 × 1/x^4 × 0.0625x^4
Simplify
2.25x^4/x^4
Cancel x^4
<u>2.25</u>
