You may be looking for the answer for this question: Before baseball practice, Jaxon Spends at least 90 minutes on homework but no more than 100 minutes. Which graphs represents the scenarios? If you are looking for the answer of the question, you are able to find the answer here.
The Answer of The Question About Jaxon Who Spends 90 Minutes on Homework
According to Brainly and answer-ya website, here is the answer for that question.
- Questions: Before Baseball Practice, Jaxon Spends at Least 90 Minutes on Homework but No More Than 100 Minutes. Which Graph Represents the Scenario?
Answer: Let x represents the number of minutes Jaxon spends on homework Before baseball practice.
Since, According to the question, Jaxon spends at least 90 minutes.
Therefore, 90 ≤ x
And, He spends no more than 100 minutes in his homework,
Therefore, 100 ≥ x
Thus, By plotting it on diagram we found the below diagram.
And here is the graph:

- Question: Layla deposits at least 25% but no more than 50% of her paycheck into a savings account. If she earns $200 per paycheck, which statements about the amount of money she deposits, s, are true? Check all that apply.
Answer: 2. 50 ≤ s ≤ 100
- She could deposit $50.
- She could deposit $75.
- Question: Does changing the compound inequality x > −3 and x < 3 from “and” to “or” change the solution set? Explain.
Answer: Sample Answer:
Yes, if you change the type of compound inequality, the solution set will change. The solution set of the “and” compound inequality contains values for x that satisfy both inequalities, which are values between -3 and 3. The solution set of the “or” compound inequality contains values for x that satisfy either or both inequalities, which includes all real numbers.
About Compound Inequalities
According to the Cliffs Notes site, here is the explanation about Compound Inequalities.
The definition of a compound inequality is a sentence with two inequality statements which are joined either by the word ‘or’ or by the word ‘and’. ‘And’ means that both statements of the compound sentence are true at the same time. It is explained that it is the overlap or intersection of the solution sets for the individual statements. How about ‘or’? It indicates that as long as either statement is true, the whole compound sentence is true. It can be said that it is the combination or union of the solution sets for the individual statements. A compound inequality which utilizes the word ‘and’ is called conjunction. As you know that ‘and’ and ‘or’ are parts of speech known as conjunction. However, the mathematical conjunction has a different meaning from the grammatical one.
You have to know that the conjunction (part of speech) ‘or’ when used in a compound inequality forms what is known as a disjunction.
On the Cliffs Notes, there are some examples of questions about it. The first example is:
You have to solve for x: 3x + 2 < 14 and 2 x – 5 > -11.
You have to solve each inequality separately. Because the joining word is ‘and’, it means that the overlap or intersection is the desired result.
3x + 2 < 14 and 2x – 5 > – 11
3x < 12 2x > -6
x < 4 x > -3
x < 4 indicates all the numbers to the left of 4, and x > -3 indicates all the numbers to the right of -3. The intersection of these two graphs is all the numbers between -3 and 4. The solution set is
{x| x> -3 and x < 4}
Another way this solution set could be expressed is
{x|-3 < x < 4}
If a compound inequality is written without the expressed word ‘and’ or ‘or’, it is understood to automatically be the word ‘and’. Reading {x| -3 < x < 4} from the ‘x’ position, you say (reading to the left), “x is greater than -3 and (reading to the right) x is less than 4.”
Well, that’s the explanation about Compound Inequalities according to the Cliffs Notes site. If you want to read more about it, you are able to access the site and learn it.
