Answer:
3/8
Step-by-step explanation:
1 - 5/8 = 3/8
The formula is V = whl.
So, it would be V= 7x2.5x3
V = 52.5.
Then, it's that x 5.
The new volume is 262.5.
Answer:
Both represent a proportional relationship
Step-by-step explanation:
This is because when the independent variable in each table increases, the dependent variable increases as well, making the relationship proportional.
Answer:
Part a) The unit rate of change of d with respect to t is equal to 
Part b) The graph of the line in the attached figure
Step-by-step explanation:
we know that
A relationship between two variables, t, and d, represent a proportional variation if it can be expressed in the form 
or 
step 1
Find the value of k
we have
substitute
so
the linear equation is equal to
step 2
using a graphing tool
graph the line
So the problem statement wants us to convert a regular equation to a linear equation form, with slope and y-axis intercept, let's do try that:
2(y - x) = 2y - 14
2y - 2x = 2y - <span>14
-2x = -14
x = 7
Therefore we cannot have an equation of the form linear with slope and y intercept, but we do have </span><span>x = 7 which is a line equation as well, it means that for any value of y, x will always be 7, that is a line parallel to y-axis passing through x = 7 point</span>
