Answer: circle e, circle f
Step-by-step explanation:
Answer:
x = 0
Step-by-step explanation:
First we set up our equation. From the picture we can see that:
11 + x + 1 = 2x + 12
Now we can gather our like terms:
x + 12 = 2x + 12
Lets subtract x from both sides to isolate the x on the left:
12 = x + 12
Next we subtract 12 from both sides
x = 0
Check the answer
11 + 0 + 1 = 2(0) + 12
12 = 0 + 12
12 = 12
The linear rule should look like this y=a*x+b
As the function graph goes through the (0,0) point, the equation 0=a*0+b <=> b=0 must be true.
Now we only need to find a, using one of the points given. With (-4, 16):
16=-4*a <=> a=16/-4 <=> a= -4
So the rule looks the following way:
f(x)= -4*x
Answer:

Step-by-step explanation:
1) Find the Greatest Common Factor (GCF).
1 - What is the largest number that divides evenly into
and
?
It is 
2 - What is the highest degree of
that divides evenly into
and
?
It is 1, since
is not in every term.
3 - Multiplying the results above,
The GCF is 4.
2) Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

3) Simplify each term in parentheses.

4) Factor out common terms in the first two terms, then in the last two terms.

5) Factor out the common term
.
