Answer:
5
Step-by-step explanation:
Let the required number be x
![\huge {x}^{9} \div {x}^{6} = 125 \\ \\ \huge {x}^{9 - 6} = 125 \\ \\ \huge {x}^{3} = 125 \\ \\ \huge x = \sqrt[3]{125} \\ \\ \huge x = \sqrt[3]{ {5}^{3} } \\ \\ \huge \red{ x = 5}](https://tex.z-dn.net/?f=%20%5Chuge%20%7Bx%7D%5E%7B9%7D%20%20%5Cdiv%20%20%7Bx%7D%5E%7B6%7D%20%20%3D%20125%20%5C%5C%20%20%5C%5C%20%5Chuge%20%7Bx%7D%5E%7B9%20-%206%7D%20%20%3D%20125%20%5C%5C%20%20%5C%5C%20%5Chuge%20%7Bx%7D%5E%7B3%7D%20%20%3D%20125%20%5C%5C%20%20%5C%5C%20%5Chuge%20x%20%3D%20%20%5Csqrt%5B3%5D%7B125%7D%20%5C%5C%20%20%5C%5C%20%5Chuge%20x%20%3D%20%20%5Csqrt%5B3%5D%7B%20%7B5%7D%5E%7B3%7D%20%7D%20%20%5C%5C%20%20%5C%5C%20%5Chuge%20%5Cred%7B%20x%20%3D%205%7D)
Answer:
3.50 + 1.84m = c
Step-by-step explanation:
Multiply 0.23 by 8 to get 1.84, the cost per mile.
Multipy that my m, the miles you drove.
Then add the initial fee of 3.50.
First thing to do is to solve each of these for y. The first one is y=-4x-3; the second one is y=4x-21; the third one is y=4x+21; the fourth one is y=-4x+3. From that you can tell the positive slopes are found in the second and third equations. Those are the ones we will test now for the point (3, -9). y=-9 and x=3, so let's fill in accordingly. The second equation filled in is -9=4(3)-21. Does the left side equal the right when we do the math? -9=12-21 and -9=-9. So the second one works. Just for the sake of completion, let's do the same with the third: -9=4(3)+21. Does -9=12+21? Of course it doesn't. Our equation is the second one above, y+9=4(x-3).
V(s) = s^3 should be the correct answer. Hope this Helps!
