Volume (cube) = side × side × side
Volume (v) =
![{a}^{3} = 8000 {ft}^{3} \\ \sqrt[3]{ {a}^{3} } = \sqrt[3]{8000 {ft}^{3} } \\ a = 20ft](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B3%7D%20%20%3D%208000%20%7Bft%7D%5E%7B3%7D%20%20%5C%5C%20%20%5Csqrt%5B3%5D%7B%20%7Ba%7D%5E%7B3%7D%20%7D%20%20%3D%20%20%20%5Csqrt%5B3%5D%7B8000%20%7Bft%7D%5E%7B3%7D%20%7D%20%20%5C%5C%20a%20%3D%2020ft)
And you can check because 20 × 20 × 20 = 8000, bc 20 × 20 = 400, and 400 × 20 = 8000
Answer:
1. -3 = -8, 0 = 1, 2 = 7
Step-by-step explanation:
1. Plug in the x values for x in the equation and graph the coordinates (examples; (-3, -8))
2. do the same thing as #1
example; y = -(-3) - 2
3. Plug in 2 into the equation, giving you your y value, and plug the coordinates in
4. you can make up the x coordinates, I would do -1, 0, 1, and 2. and just plug those in for the x in the equation and graph.
5. Follow the same steps as the last problems but just connect the points
6. Same steps as the other problems, just pick some points and plug them into the equation.
I hope this helps
Answer:
Step-by-step explanation:
If the value of y is same for both then we have equal right sides of equations
Solve this for x
- 50x - 30x = 70 - 10
- 20x = 60
- x = 60/20
- x = 3
Find the value of y
- y = 50*3 + 10 = 150 + 10 = 160
Correct choice is A
