Use the binomial theorem:

In this case,

The
term occurs for
:

Answer:
(-1 / 4)x + y = -1.75
Step-by-step explanation:
Standard form is Ax + By = C
First I'm going to write it in point slope form, then I'm going to simplify.
Slope: (-3 + 1) / (-5 - 3) = 1 / 4
(y + 1) = 1 / 4(x - 3)
y + 1 = x / 4 - 3 / 4
(-1 / 4)x + y = -1.75
This might be wrong because I don't really like to use standard form.
Step-by-step explanation:
the given function: 
Where C = cost (in dollars) and x is the number of miles you drive the truck.
when we compare the given function by slope- the intercept form y=mx+b, what we get is
Slope m = 0.5 whose fraction can be written as 
And y-intercept b =70.
for us to be able to graph it, we need to plot y-intercept from 70 and then plot some more points by applying or increasing the points by 
the shaded lines on the graph indicates the given function.
cost is at $70 for 0 number of miles. travelled.
Thus;
the Domain: x≥0 and Range :
≥
The ratio of the smaller to the larger is given as 2:4. Another way to write this is as a fraction:

which of course you can see now will reduce to

. That's your ratio.
Answer:
5
Step-by-step explanation:
4x +5= 5x
Then solve the linear eqn
