Answer:
(3,-1)
Step-by-step explanation:
So we have the system of equations:

As directed, add straight down. The y-variable will cancel:

Now, divide both sides by 5. The left cancels:

So x is 3.
Now, substitute 3 for x in either of the equations:

Substitute 3 for x:

Multiply:

Subtract 9 from both sides:

So, our answer is: x=3, y=-1 or (3,-1).
And we are done :)
Answer: The sequence does not have common ratio.
Step-by-step explanation:
By definition, a sequence with a constant ratio (common ratio) between terms is called a "Geometric sequence". In order to find the common ratio, it is necessary to divide any term in the sequence by the previous term.
In this case, given the sequence:

We get:

Since the ratios between the terms are not constant, we can conclude that <em>the sequence does not have common ratio.</em>
Answer:
Linear systems are systems of equations in which the variables are never multiplied with each other but only with constants and then summed up
Answer:
3rd degree trinomial
Step-by-step explanation:
the highest power is 3 and there are 3 terms so its a 3rd degree trinomial
Solve for x.
First multiply everything in the parenthesis by 3.
12 + 12x = 12 + 12x
There is an infinite amount of solutions.
Hope this helps!
