Answer: -2
Step 1: Write an equation
Before we are able to solve, we need to write an equation. We can do this by breaking down the equation. We are told to find the sum of -4 and the difference of another two numbers. Sum means addition, so we will add -4 to the difference of 3 and 1. Because we are adding to the difference, we will put 3 and 1 inside of parentheses, and find the difference before we add. Knowing this, we can write the equation. Let’s do this now.
-4+(3-1)
Step 2: Solve
Now that we have the equation we can solve for the answer. Let’s start by finding the difference, as indicated by the parentheses. After that, we can find the sum of that number and -4 by adding them together. We can do this now.
-4+(3-1)
-4+2
-2
This is your answer! The sum of -4 and the difference of 3 and 1 is -2. Hope this helps! Comment below for more questions.

Answer:
f(-1) = -1
Step-by-step explanation:
x = -1 falls in the middle segment, where -2 < x < 2. So, the applicable function definition is ...
f(x) = -2x -3
f(-1) = -2(-1) -3 = 2 -3
f(-1) = -1
Answer:
x=−4y+10
Step-by-step explanation:
Let's solve for x.
−x−4y=−10
Step 1: Add 4y to both sides.
−x−4y+4y=−10+4y
−x=4y−10
Step 2: Divide both sides by -1.
