Answer:
1 hour and 25 minutes
Step-by-step explanation:
There is a 2 1/2 grid unit separation. If each grid unit represents 20 miles, there is a 50 mile separation. 50/40=1.25. It will take a truck driving at 40 miles per hour 1 hour and 25 minutes to drive from warehouse N to this store.
Xy=200
x=2y
(2y)y=200
2y^2=200
y^2=100
y=10, x=20
10, 20
Answer:
B
Step-by-step explanation:
A proportional relationship is represented by linear function with its linear parameter "b" equal to zero. Since b is equal to zero, the line passes through the origin and the function/relation is proportional.
To verify that we divide the y coordinate over the x coordinate we obtain a constant called k, which is the slope.
For instance:
![y=2x](https://tex.z-dn.net/?f=y%3D2x)
According to this function we can easily check a proportional relationship among its points:
![(1,2), (2,4), (4,8), (6,12), ...](https://tex.z-dn.net/?f=%20%281%2C2%29%2C%20%282%2C4%29%2C%20%284%2C8%29%2C%20%286%2C12%29%2C%20...)
![k=\frac{y}{x}=\frac{2}{1}=\frac{4}{2}=\frac{12}{6}\Rightarrow k=2](https://tex.z-dn.net/?f=k%3D%5Cfrac%7By%7D%7Bx%7D%3D%5Cfrac%7B2%7D%7B1%7D%3D%5Cfrac%7B4%7D%7B2%7D%3D%5Cfrac%7B12%7D%7B6%7D%5CRightarrow%20k%3D2)
A. 1 pound of cherries costs 2.50
B. Yes it is constant
C. I believe that you would put cost on the y and lbs on the x
E. 5 lbs of cherries = 2.50 x 5 = $12.50
