The equation

means that you choose a value for the input variable t, and you compute the correspondent value for the output variable w.
So, if the input is t = 176, the output will be

Similarly, the ordered pair (4, 144) means that if you choose 4 as input, you get 144 as output, in fact you have

3.625 as a mixed number or fraction is 29/8 or 3 5/8

Answer:
or 
Step-by-step explanation:
The question is
Find the slope intercept form of the line parallel to the line 5x+8y=120 passing through (4,5)
step 1
Find the slope of the given line
we have

isolate the variable y


The slope of the given line is m=-5/8
step 2
Find the slope of the line parallel to the given line
we know that
If two lines are parallel, then their slopes are the same
so
The slope of the parallel line to given line is m=-5/8
step 3
Find the equation of the line into slope intercept form
The equation of the line into slope intercept form is equal to

we have
m=-5/8 and point (4,5)
substitute and solve for b



substitute

Speed = Distance/Time = 160/8 = 20 miles/hour
Answer:
65
Step-by-step explanation:
70 - 60 = 10
10 / 2 = 5
Thus 65
