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>:

\sqrt{\frac{1}{196} }

Apply the square root to both the numerator (top number) and denominator (bottom number).

= \frac{\sqrt{1} }{\sqrt{196} }    

Solve for the square root of 1.

= \frac{1}{\sqrt{196} }

Solve for the square root of 14.

= \frac{1}{14}                      Final answer

I hope this helps! Check out this problem to learn more about these topics:

Figure a is dilated by a scale factor of 1/2 to form figure b. What is the length of x?
PIT_PIT [208]

Answer:

The correct option is 3. The value of x is 8 inches.

Step-by-step explanation:

It is given that Figure A is dilated by a scale factor of 1/2 to form Figure B. It means both figure are similar and corresponding sides of similar figures are proportional.

\text{scale factor}=\frac{\text{Side of image}}{\text{Side of preimage}}

\frac{1}{2}=\frac{x}{16}

Multiply both sides by 16.

\frac{16}{2}=x

8=x

Since scale factor is 1/2, so we can directly say that the side length of image is half of the corresponding side of preimage.

The length of x is 8 inches. Therefore the correct option is 3.

Can i get some help on my test please?
Veseljchak [2.6K]

Answer:

Not proportional.

Step-by-step explanation:

The butterfly method multiples it like a butterfly. Ex. 5 times 3 is 15. 8 times 2 is  16. Therefore, not proportional.
