Step-by-step explanation:
Given system of equations are
Now to the solution:
To solve the given system of equations using substitution method.
That is substitute equation(1) in equation (2) we get
(here y=-3x)
(adding the like terms)
Therefore x=7
Now substitute x=7 in equation (1) we get
Therefore the solution is (7,-21)
Therefore Option- one is correct.
The given system of equations have one solution that is (7,-21)
Answer:
Step-by-step explanation:
To find (fg)(x), we have to look at f(x) and g(x) and multiply the two quantities together. We are already given the two quantities individually so all that is left is the multiplication:
If we reorder the terms to go from highest degree to lowest, we get our final answer to be the following:
