Answer:
Option C. Yes; y=2x
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
so
In this problem
For x=0, y=0
That means ----> the line passes through the origin
<em>Find the value of k</em>
For x=2, y=4
---->
For x=4, y=8
---->
The values of k are equal
therefore
The table represent a direct variation
The equation is equal to
Answer:
volume = 720 in³
Step-by-step explanation:
volume = 1/3Bh = 1/3 x 72 x 30 = 720 in³
L x w = 150+175t
=> l = (150+175t)/25
l = [25(6+7t)/25]
l = 6+7t
The expression of the length is l=6+7t
