Answer:
A.
Step-by-step explanation:
Divide the height of the container by the number of balls in the container. It will tell you what the length of each ball is . The length of each ball = the diameter. circumference = diameter/2
Answer:-12+6y
Step-by-step explanation:
Since the 12 is a negative and the 6y is a positive you can switch it around.
Answer:
0.5
Step-by-step explanation:
For x = 1/3,
![y = f(\frac{1}{3}) = (\dfrac{1}{8})^\frac{1}{3} = \sqrt[3]{\dfrac{1}{8}} = \dfrac{1}{2} = 0.5](https://tex.z-dn.net/?f=%20y%20%3D%20f%28%5Cfrac%7B1%7D%7B3%7D%29%20%3D%20%28%5Cdfrac%7B1%7D%7B8%7D%29%5E%5Cfrac%7B1%7D%7B3%7D%20%3D%20%5Csqrt%5B3%5D%7B%5Cdfrac%7B1%7D%7B8%7D%7D%20%3D%20%5Cdfrac%7B1%7D%7B2%7D%20%3D%200.5%20)
Answer:
100
Step-by-step explanation:
300 + 300 = 600
600 - 500 = 100
Answer:
y= 35/2 when x=5
x=6 when y =21
Proportinal relatiionships: y=−x
, y=15x
Step-by-step explanation:
The formula for direct variation is
y= kx
If y=7 and x=2, we can solve for k
7 =k*2
Divide by 2
7/2 =k
y =7/2 x
Now if x=5
y =7/2 * 5
y =35/2
Now if y=21
21 =7/2 * x
Multiply by 2/7
21 * 2/7 = 7/2 * 2/7 x
6 =x
Which equation represents a proportional relationship?
y=−x
YES k = -1 Some people debate about having a negative constant, but everything I have read and taught says you can have a negative constant.
y=−5(x+1)
This does not go through the origin so no
if x=0 y = -5
y = 5x + 1
if x = 0 y =1 so no
y=15x
YES k = 15
