Answer:
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
Let
x -----> the number of hours worked
y ----> the amount paid in dollars
In this problem we have a proportional variation, between two variables, x, and y
<em>Find out the constant of proportionality k</em>
For (5,300) -----> 
----> 
For (4,240) -----> ----> 
For (6,360) -----> ----> 
The constant k is
The equation is equal to
The unit rate of change of dollars with respect to time is equal to the constant of proportionality or slope of the linear equation
therefore
Answer:
Step-by-step explanation:
First, in order to get rid of the parenthesis, you need to multiply 2.5 with whatever is in the parenthesis.
Multiply 2.5 on each side of the equation like this:
(12.75 x 2.5) (24.50 x 2.5) =188.75
Once you're finished, you should get 61.25 and 31.875x =188.75
Now in order to find 'x' you will need to subtract 61.25 to each side of the equation like this:
61.25 - 61.25 = 0
188.75 - 61.25 = 127.5
So now your equation should look like this:
31.875x = 127.5
You have to divide 31.875 by each side now.
Once you divide them, your final answer should be 4.
so x = 4.

Answer:
y=7x+5
Step-by-step explanation:
y-y1=m(x-x1)
y-(-9)=7(x-(-2))
y+9=7(x+2)
y+9=7x+14
y=7x+14-9
y=7x+5

Answer:
F has 10 marbles and I has 5 marbles.
Step-by-step explanation:
First, I subtracted 10 from 15 since F has 10 more marbles than I. When I subtracted I got 5.
Hope this helps!!!!
