When solving a linear inequality, what is different compared to solving a linear equa- tion? For which steps do you have to hbe

more careful now? (ii) Write down your own explicit questions about the reading, ready to bring up in class You can also mention a specific example or definition in the lecture notes that is still not clear to you, so the professor can expand on those ideas. Be as specific as possible. (ii) Reflection: Write one, two or maybe three sentences with your thoughts about the section that you read, what was well explained and interesting, what you had to re- read to understand, ete. You can also mention how the semester is going for you and any suggestions that you have to improve the class.

Answer:

See explanation below

Step-by-step explanation:

When solving a linear inequality, the main difference resides in the following:

When we change the signs of the terms (either from positive to negative or from negative to positive) we have to change the sign of the inequality (if the sign was ≥, we change it to ≤, if the sign was ≤, we change it to ≥). Therefore we have to be more careful while doing this.

5. How many solutions does this system of equations have?
Diano4ka-milaya [45]

Answer:

\text{\boxed{\sf{D. \ No\  solution}}}

Step-by-step explanation:

Isolate the term of x and y from one side of the equation.

<h3>y=-4x-9 and y=-4x-1</h3>

First, you have to substitute of y=-4x-1.

\Longrightarrow: \sf{[-4x-1=-4x-9]}

<u>Add by 4x from both sides.</u>

\Longrightarrow: \sf{-4x-1+4x=-4x-9+4x}

<u>Solve.</u>

\Rightarrow:\sf{-1=-9}\\\\\Rightarrow: \sf{(-9)-(-1)=-9+1=-8}\\\\\Rightarrow: \sf{8=0}

  • <u>Therefore, the correct answer is "D. No solution".</u>

I hope this helps. Let me know if you have any questions.

4 - x + <img src="https://tex.z-dn.net/?f=6%5E%7B2%7D" id="TexFormula1" title="6^{2}" alt="6^{2}" align="absmiddle" class="latex
Lemur [1.5K]

Answer:

x ≤ 19

Step-by-step explanation:

The instructions here are probably "solve for x."  Please include them.

4 - x + 6^2 ≥  21

becomes 4 - x + 36 ≥  21

Now combine like terms.  4 and 36 combine to 40:  40 - x ≥ 21, and so:

19 - x ≥ 0

Adding x to both sies results in

x ≤ 19

Please, include the instructions when you post a question.  Thanks.
