What two numbers add to equal -11 and multiply to equal 28?What two numbers add to equal -20 and multiply to equal 51?
What two numbers add to equal -5 and multiply to equal -36?

Answers

Answer 1
Answer: -4 + -7 = -11      4 * 7 = 28
-17 + -3 = -20    17 * 3 = 51
4 + -9 = - 5      4 * -9 = 36
Answer 2
Answer: the answer for first is -4 and -7 (-4 + -7) = 11 , -4 x -7 = 28

The answer to the second is -17 and -3 (-17+-3) = 20,  -17 x -3 = 51

The answer to the third is -9 and 4  ( -9 + 4)  = -5 , -9 x 4 = -36

The answer is obtained by hit and trial method and there are many other algebraic ways to solve this. Since it was a bit easy one, i thought to apply the hit and trial method.

Final answer:

The solution to the given inequality, |2x + 1| ≤ 3, is the set { -2 ≤ x ≤ 1 }, which corresponds to answer choice (c). This is achieved by solving two separate inequalities, 2x + 1 ≤ 3 and - (2x + 1) ≤ 3.

Explanation:

The subject of the question is Mathematics, specifically a High School algebra topic on solving absolute inequalities. The student's question is asking us to solve the inequality |2x + 1| ≤ 3. To do this, we need to create and solve two separate inequalities: 2x + 1 ≤ 3 and - (2x + 1) ≤ 3.

Solving 2x + 1 ≤ 3 gives us 2x ≤ 2 and x ≤ 1 . Solving - (2x + 1) ≤ 3 gives us -2x - 1 ≤ 3 , then -2x ≤ 4 , and finally x ≥ -2 . Combining these answers gives us the solution set { -2 ≤ x ≤ 1 }, which corresponds to answer choice (c).
