Hope this helps.
Answer:
no
Step-by-step explanation:
Neither 10 nor 34 are divisible by 4
Thus 4 is not a factor of the expression.
Answer:
<h2>2</h2>
Step-by-step explanation:


Answer:

Step-by-step explanation:
The given system is:


Since I prefer to use smaller numbers I'm going to divide both sides of the first equation by 3 and both sides of the equation equation by 6.
This gives me the system:


We could solve the first equation for
and replace the second
with that.
Let's do that.

Subtract
on both sides:

So we are replacing the second
in the second equation with
which gives us:





Now recall the first equation we arranged so that
was the subject. I'm referring to
.
We can now find
given that
using the equation
.
Let's do that.
with
:



So the solution is (8,-1).
We can check this point by plugging it into both equations.
If both equations render true for that point, then we have verify the solution.
Let's try it.
with
:


is a true equation so the "solution" looks promising still.
with
:


is also true so the solution has been verified since both equations render true for that point.
Answer: 8.75
Step-by-step explanation:
12.50 x 30% or .03
= 3.75
3.75 - 12.50
= 8.75
