Hi there!
Let me know if you have questions about my answer:
3. c. 7+(y+2)
4. a. 1/14
Step-by-step explanation:
<u>Question 3</u>:
The word phrase is: "the product of 2 more than y and 7".
Let's break down each part of the phrase.
"y and 7" is a way of showing addition.
y + 7
"Product" means the answer to a multiplication question. If you multiply more than one term, you can put a bracket around them and write the factor on the outside.
"Product of 2" means 2 is multiplied.
Therefore, the answer is 2(y + 7).
<u>Question 4</u>:
Apply the square root to both the numerator (top number) and denominator (bottom number).
Solve for the square root of 1.
Solve for the square root of 14.
Final answer

Answer:
1. value is 0; x-3 is a factor . . . . . . . . . . . . . .third choice
2. evaluates at x = -1; remainder is -11 . . . . first choice
Step-by-step explanation:
Dividing f(x) by (x -a) gives ...
f(x)/(x -a) = g(x) +r/(x -a) . . . . some quotient and a remainder r
If we multiply this expression by (x -a), we see ...
f(x) = (x -a)g(x) +r
so
f(a) = (a -a)g(a) +r . . . . . evaluate the above equation at x=a
f(a) = 0 +r
f(a) = r . . . . . . . . . a statement of the remainder theorem
If r=0, then x-a is a factor of f(x) = (x-a)g(x).
___
1. We have "a" = 3, and f(3) = 0. Therefore (x-3) is a factor.
__
2. We have "a" = -1, and f(-1) = -11. Therefore the remainder from division by (x+1) is -11.
