The first expression is equivalent to B
The second expression is equivalent to A
The third expression is equivalent to C
You are basically adding like terms. For example for the first expression, it is 7x^2 + 2x^2, which equals 9x^2. Remember since you're adding, do not add the exponents.
The linear inequality of the graph is: -x + 2y + 1 > 0
<h3>How to determine the
linear inequality?</h3>
First, we calculate the slope of the dashed line using:

Two points on the graph are:
(1, 0) and (3, 1)
The slope (m) is:

This gives
m = 0.5
The equation of the line is calculated as:

So, we have;

This gives

Multiply through by 2

Now, we convert the equation to an inequality.
The line on the graph is a dashed line. This means that the inequality is either > or <.
Also, the upper region of the graph that is shaded means that the inequality is >.
So, the equation becomes
2y > x - 1
Rewrite as:
-x + 2y + 1 > 0
So, the linear inequality is: -x + 2y + 1 > 0

Find a linear inequality with the following solution set. Each grid line represents one unit. (Give your answer in the form ax+by+c>0 or ax+by+c
0 where a, b, and c are integers with no common factor greater than 1.)
Answer:
x = 20/33
Step-by-step explanation:
-6.6x = -4
Divide both sides by -6.6.
x = -4/(-6.6)
x = 40/66
x = 20/33
The answer is B for that question.
