There are 13 students in Sara's class. I did this by using 8 = 3/5x, x being the total number of students. The answer is 13.33334 but you cant have half a student so it rounds down to 13.
also number 4 can be any positive number. This is because if you take one fourth of a negative number it will be more than if you doubled it. for example 1/4 of -4 is -1 which is more than -4 doubled which is -8

Given: AB = 12
Alexxx [7]

In proving  that C is the midpoint of AB, we see truly that C has Symmetric  property.

<h3>What is the proof about?</h3>

Note that:

AB = 12

AC = 6.

BC = AB - AC

= 12 - 6

=6

So, AC, BC= 6

Since C is in the middle, one can say that C is the midpoint of AB.

Note that the use of segment addition property shows: AC + CB = AB = 12

Since it has Symmetric property, AC = 6 and Subtraction property shows that CB = 6

Therefore,  AC = CB and thus In proving  that C is the midpoint of AB, we see truly that C has Symmetric  property.

See full question below

Given: AB = 12 AC = 6 Prove: C is the midpoint of AB. A line has points A, C, B. Proof: We are given that AB = 12 and AC = 6. Applying the segment addition property, we get AC + CB = AB. Applying the substitution property, we get 6 + CB = 12. The subtraction property can be used to find CB = 6. The symmetric property shows that 6 = AC. Since CB = 6 and 6 = AC, AC = CB by the property. So, AC ≅ CB by the definition of congruent segments. Finally, C is the midpoint of AB because it divides AB into two congruent segments. Answer choices: Congruence Symmetric Reflexive Transitive

What are the zeros of the function below?
Ivan
When you want to find zeros of rational expression you need to find at which points numerator is equal to zero. In this case, we have the product of three expressions.
x(x-1)(x+11)=0
A product is equal to zero whenever one of the factors is equal to zero. 
That means that zeros of our functions are:
1)x=0
2)x-1=0
x=1
3)x+11=0
x=-11
The final answer is a. Function has zeros at (0, 1, -11).
