Hello!
We'll start by simplifying the required formula. (f – g)(x) can be rewritten as the following:
f(x) – g(x)
Now insert any known values into the simplified formula above:
(-5x – 4) – (-3x – 2)
Eliminate the parentheses by simplifying:
-5x – 4 + 3x + 2
Combine like terms:
-2x – 2
We have now proven that (f – g)(x) is equal to (-2x – 2).
The correct answer is C.
I hope this helps!
Answer:
We conclude that a researcher used simple random sample.
Step-by-step explanation:
We know that select a sample of five children from a class of 30, a researcher puts each child’s name on a slip of paper, then shuffles the papers in a hat and randomly picks five names.
We conclude that a researcher used simple random sample.
Because every children has an equal chance of being included in the sample.

<h3>What is Unitary Method?</h3>
Unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Sue spent 1 hour 19 minutes less than Jared
Lucas spent 45 minutes less than Pete.
Pete spent 3 hours reading.
Since, pete spent 3 hours. So, Jared spent
= 3 hours or (180 minutes) - 45 minutes
= 2 hours 15 minutes.
Now, Seu spent = 2 hrs 15 minutes - 1 hour 19 minutes
= 56 minutes
