Answer:
C
Step-by-step explanation:
The 3 is directly outside the parentheses, meaning you need to distribute the 3 to the x and the 4 because they are inside the parentheses. There is no addition, subtraction, or division involved in this so C is correct.
Answer:
the answer is (-4, 5)
Step-by-step explanation:
Let's use elimination by addition / subtraction:
-6x - 2y = 14
6x + 7y = 11
-------------------
5y = 25, so y = 5.
Substituting 5 for y in the 2nd equation, we get:
6x + 7(5) = 11, or:
6x + 35 = 11, or
6x = -24, or x = -4.
Thus, the answer is (-4, 5). Please double check to ensure you have copied down both system of equations and answer correctly.
Check: Is (-4, 5) a solution to this system?
Subst. -4 for x and 5 for y in the first equation:
-3(-4) - (5) = 7
12 - 5 = 7 YES
Quotient means division, which is obvious by all the division answers.
It says "Quotient of 4 AND ..." which means that four will be on top and everything else will be on the bottom.
So now you have:
![\frac{4}{?}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B%3F%7D%20)
four over something unknown.
Reading the rest of the question, "the sum of a number and three"
Sum means addition, again obvious by the answer choices.
"a number" is an unknown, so we can set that to x
and this x is being added to by three, so therefore
x+3 would be in your denominator.
You final equation should look like this:;
![\frac{4}{x+3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7Bx%2B3%7D%20)
OR answer choice
