Answer:
C.
Step-by-step explanation:
Even though it is absolute value, 17 is still the greatest answer. If a number is in absolute value it will never be negative, only positive values can come out of an absolute value.
An example for absolute value would be if you had to measure the amount of distance away from something, even if its behind you, it would still be a positive number of length away from you.
If you had the absolute value of -25, it would automatically be equal to 25.
So circling back to the original problem, the absolute value of 17 would be greater than 3, -4 and -8. If (hypothetically) it was the absolute value of -17 it would still be greater because it would equal 17.
I hope that made sense, im sorry that it's a bit lengthy. Have a good day :)

Answer:</h3>
D. This is an experiment because it is applying a treatment
<h3>
Step-by-step explanation:</h3>
Experiments and observational studies are both ways to find new information about a hypothesis but in different ways.
Vocabulary
First, to understand the question, let's define the key terms.
- Experiment - An experiment is when a scientist purposely applies a treatment and interferes with a person's life in order to gather information.
- Observational Study - This type of study attempts to study a person without interfering with their lives in any way.
These definitions eliminate the answer choices A and C because both of them match the incorrect definition of the term.
Experiment vs. Observational Study
Now, we need to figure out if this specific example is an experiment or an observational study. In this case, the nutritionist is giving a treatment of vitamins. This means that this cannot be an observational study because the scientist is interfering with people. It has to be an experiment because there is a specific treatment being applied.
Answer:
x+4y=-35
-8x-4y=28
Step-by-step explanation:
The answer to the original equations is (1, -9). You can solve that by using substitution by moving the 4y over and substituting that equation for x on the second part of the top equation. Using elimination, the second set of answers will give you the same, (1, -9)!
Your answer is 43 / 4.
