What is the solution of the following system -2x-y=1 -4x-2y=-1
2 answers:
Answer: The correct option is
(B) no solution.
Step-by-step explanation: We are given to find the solution to the following system of equations :
From equation (i), we have
Substituting the value of y from equation (iii) in equation (ii), we get
which can never be possible.
Therefore, the given system of equations has no solution.

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 : ≥
