It's A:
(-∞, -5]
And the set-builder notation is:
{y|y < -5}
that'd be a segment.
⭕-------------------------------------⭕
Answer:8x-5y
Step-by-step explanation:
(3x-4y)-(-5x+y)
Remove brackets
3x-4y+5x-y
Collect like terms
3x+5x-4y-y
8x-5y
Option C
When
is subtracted from
then the result is 
<h3><u>Solution:</u></h3>
Given that
is subtracted from 
We have to find the result
Subtraction is a mathematical operation that tells us the difference between two numbers.
When "a" is subtracted from "b", we write in mathematical expression as "b - a"
So
is subtracted from
is written mathematically as:

<em><u>Expanding the above expression using algebraic identity:</u></em>


Multiplying the nnegative sign with terms inside bracket
<em><u>There are two simple rules to remember: </u></em>
- When you multiply a negative number by a positive number then the product is always negative.
- When you multiply two negative numbers or two positive numbers then the product is always positive.

Hence the result is:
