Which values are in the solution set of the inequality -9/4x+12≥-8? Select all that apply. A. 6 B. 7 C. 8 D. 10 E. 11
Answers
Answer: A, B, C
Step-by-step explanation:
To solve for the inequality, we would solve it as if it had an equals sign.
[subtract both sides by 12]
[multiply both sides by -4/9, remember to flip inequality]
Now, we know that the solution is less than or equal to 80/9, which is approximately 8.89.
Looking at the answer choices, A, B and C are the answers since they are both less than 8.89.
Final answer:
The solution to the inequality is all x that are less than or equal to 8.89. Therefore, from the given options A. 6, B. 7, and C. 8 are in the solution set.
Explanation:
To find the values in the solution set of the inequality -9/4x+12≥-8, we need to isolate x by subtracting 12 from both sides of the inequality giving us -9/4x≥-20. Then, we can solve for x by dividing both sides of the inequality by -9/4, remembering to reverse the inequality symbol because we are dividing by a negative number. This gives us x≤(20)(-4/9), which simplifies to x≤80/9. Now, we can check which values from the options A, B, C, D, and E are less than or equal to 80/9.
- A. 6: 6 is less than or equal to 80/9.
- B. 7: 7 is less than or equal to 80/9.
- C. 8: 8 is less than or equal to 80/9.
- D. 10: 10 is not less than or equal to 80/9.
- E. 11: 11 is not less than or equal to 80/9.
Therefore, the values in the solution set of the inequality are A, B, and C.

The best way to find percent is to use proportion. After using proportion your answer would probably be 84$. Remember the percent always goes over 100. so u would put 40 over 100 and 210 under n which is the part you don't know.

Answer:
2(8+7)
Step-by-step explanation:
sum is addition so add 8+7 then its doubled so u put parenthesis and double by 2
Final answer:
The sum of 8 and 7, doubled, is calculated by first adding 8 and 7 to get 15. Then, the 15 is doubled resulting to 30.
Therefore, the numerical expression that represents the sum of 8 and 7 doubled is 30.
Explanation:
The question asks for the sum of 8 and 7, doubled. We first do the operation within parenthesis, then double (multiply by 2) the result. Here's the step-by-step process:
- Add 8 and 7 to get 15.
- Double the result of 15 by multiplying it by 2. So, 15 x 2 equals 30.
Therefore, the numerical expression that represents the sum of 8 and 7 doubled is 30.
