This is very similar to solving linear equations except for one thing, If we multiply or divide by a negative number, we must flip the inequality sign.
<h3>What is linear inequality?</h3>
In mathematics, inequality occurs when a non-equal comparison is made between two mathematical expressions or two numbers. In general, inequalities can be either numerical inequality or algebraic inequality or a combination of both.
To better understand it, let's examine the example.
2x - 5 < 3
So, when we solve, let's just consider the inequality sign like a regular equal sign.
Let's start by adding 5 to each sides.
2x - 5 + 5 < 3 + 5
To find the value of x , we must divide it by two.
2x/2 <8/2
And the final result is x= 4.
This is our answer.
So if we need to graph it, let’s draw a number line and draw an open circle at 4. Open circle because x is not equal to 4. Then make an arrow going to the left.

Answer:
6
Step-by-step explanation:
We calculate this by multiplying the number of cookies by the number of boxes:
28*14=(20+8)*14=280+80+32=360+32=392 (that's how I like to count it, there are also other methods)
so she has 392 cookies in common.
Answer:
<h2>A'(-1, -4)</h2>
Step-by-step explanation:
A(x, y)
reflected across the x-axis: A'(x, -y)
reflected across the y-axis: A''(-x, y)
We have A(1, 4)
reflected across the x-axis: (1, -4)
and then reflected across the y-axis: A'(-1, -4)
Answer:
a = 8 * (2)^(2x)
Step-by-step explanation:
There are 2 12hours periods in a day
a = 8 * (2)^(2x)
