3 is the answer
Factors of 48: 1,2,3,4,6,8,12,16,24,48
Answer:
C. 
Step-by-step explanation:
Lets plug in -2 into each of these equation to see which one gives us the solution of -6
A. 

B. 

C. 

D. 

As we can see, function C was the only one that gave us the value of -6, so that is our answer.
The last one is the good one.
The point slope formula is,

Where,

And,


So,

So we are going to make this into a equation and evaluate it:
20 = (n ÷ 5) x 2
This is a two-step equation.
First we divide both sides by 2. We now have:10 = n ÷ 5
Then we multiply each side by 5. Now we have the final answer:50 = n
The two-digit number is 50, hope this helps!
