Question

What are the possible values of y if x =4 in the inequality x-2y ≤ 5?​

Answer 1

Answer:

y ≥ -0.5

Step-by-step explanation:

First, we can substitute 4 in for x in the inequality.

4 - 2y ≤ 5

Now, to solve for y, we start by subtracting 4 from both sides:

-2y ≤ 1

And divide by -2.  When dividing or multiplying by a negative number while solving an inequality, we also have to remember to switch around the inequality sign.  This gives us:

y ≥ $\frac{1}{-2}$ or y ≥ -0.5

Therefore, the possible values of y are -0.5 or greater.
