Answer:

Step-by-step explanation:
Given:
The table is given as:
x 0 4 7 8
y 0 24 42 48
The relationship between 'x' and 'y' is a proportional relationship.
A proportional relationship is one in which one variable varies directly with the other by a factor of 'k' also known as constant of proportionality and 
A proportional relationship is given as:

Now, we plug in 'x' and 'y' values and find the value of 'k'.
Let 

Therefore, the constant of proportionality is 6. Hence the complete equation is given as:

Step-by-step explanation:
domain = {-7, -3, 1}
range ={-8, -5, 7, 8}
Answer:
£1 = 25 hits
Step-by-step explanation:
Will get the equation is

so, X=25
x = What we want to find
For the first question, divide 32 by 40 and it should equal .8 miles. Then, for the second question, multiply .8 by 13 and it should equal 10.4 miles.
