Answer:
The true statement is: In step 3 she needed to subtract c rather than divide.
Step-by-step explanation:
Lets solve our equation step by step.
Step 1. Since 3 is the denominator of the right hand side, we need to multiply both sides of the equation by 3:
Now we can cancel the 3 in the numerator and the 3 in the denominator to get
As you can see, the first statement is false
Step 2. Since we want to isolate the variable , we need to subtract b from both sides of the equation:
The second statement is also false
Step 3. The last thing we to do to isolate (and solve for it) is subtract c from both sides of the equation:
Therefore, the third statement is true: In step 3 she needed to subtract c rather than divide.
If you wrote the expression correctly, then
Is a polynomial, and thus defined everywhere: its domain is the set of all real numbers.
If, by chance, you meant
Then we must exclude the point x=4 from the domain, since that value would cause the denominator to vanish. So, the domain would be the set of real numbers, minus the number 4.

Answer:
B. 16
Step-by-step explanation:
To find the median, you must first order the numbers from least to greatest
12
12
14
18
20
23
Next, you look for the middle number. If there is no middle number, you look for the middle 2 numbers. In this case, we will need to use the middle 2 numbers. They are 14 and 18. To find the median, you must add 14 and 18 then divide it by 2.
14 + 18 = 32
32/2 = 16
So, our answer is B. 16
