Answer:
Step-by-step explanation:
yz+4z=z-y²
yz+4z-z=-y²
yz+3z=-y²
z(y+3)=-y²
![z=-\frac{y^2}{y+3 }](https://tex.z-dn.net/?f=z%3D-%5Cfrac%7By%5E2%7D%7By%2B3%20%7D)
1 over 2, 3 over 2 is the correct answer.
Answer:
C
Step-by-step explanation:
To find the slope between any two points, we can use the slope formula:
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Where (x₁, y₁) and (x₂, y₂) are two, separate points.
We have the two points (-3, 3) and (-1, -1).
So, let (-3, 3) be (x₁, y₁) and let (-1, -1) be (x₂, y₂).
Substitute them into the slope formula to get:
![m=\frac{-1-3}{-1-(-3)}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-1-3%7D%7B-1-%28-3%29%7D)
Subtract:
![m=\frac{-4}{2}=-2](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-4%7D%7B2%7D%3D-2)
Hence, our slope is -2.
So, our answer is C.
Answer: Not really sure what you mean by algebra tiles but I do know that x=2.
Answer:
D. 144
Step-by-step explanation:
Find volume of shipping container:
2 2/3 = 8/3
2 x 1 = 2
8/3 x 2/1 = 16/3
Find volume of cube:
1/3 x 1/3 = 1/9 x 1/3 = 1/27
Find how many boxes fit in container:
16/3 ÷ 1/27
16/3 x 27/1
Simplify:
16/1 x 9/1 = 144/1
Answer: 144
