Yes algebra!!! Anyways, the m of y=mx+b is the slope of the graph, this affects the graph by making the line go in a angle either negatively or positivly
B is where the plot lies on the y line (up and down)
On the 14 week Juan will save $ 52 because each 3 week he earns 3.
So you do 9 divide by 3 and get 3. Then you do 3 times 2 and get 6.
46 + 6 = 52

For systems of equations try using graphing, substitution, and elimination. For example
{2x+7y=3}
{x=-4y}
You should first look at if you have a variable that can be substituted (using substitution) and in this case we do! you plug in the x into 2x meaning 2(-4y)+7y=3
1) distribute -8y+7y=3
2) combine like terms in this case -8y+7y= -1y
3) solve -1y=3
y=-3
so currently our solution is (0,-3)
now we solve for x.
we plug our solved variable (y) into 7y
7(-3) and our equation looks like this
2x+7(-3)=3
1) distribute 7(-3)=-21
2) rewrite then solve 2x+(-21)=3
3) isolate variable -21+21 & 3+21
4) 2x=24
5) solve 2/24 = 12
Meaning our solution is (12,-3)
This is how to solve by substitution.
Answer:
A: 
B: 
Step-by-step explanation:
<u>A:</u>
Our expression is 
. We need to find some common factors. Clearly, we can see that both terms share the x² part, so we can definitely take that out:
Let's see if 96 is divisible by 6:
96 ÷ 6 = 16; since there's no remainder / the remainder is 0, we know 96 is divisible by 6, so we can also factor out 6:
Thus, the answer to part A is .
<u>B:</u>
Look at the 
part of the above factored expression. Notice that it is a difference of squares (because 
and 16 = 4²), so we can write this as:
Now take a look at the 
part. Again, it's a difference of squares because 
and 4 = 2², so rewrite that as:
Put it all together:
Thus, the answer to part B is .
