Question

Which number line represents the solution of 1 - 2x > 3?

A)
B)
C)
D)

Answer 1

To solve the inequality 1 - 2x > 3, subtract 1 from both sides to get -2x > 2, then divide by -2 and flip the inequality sign to get x < -1. The number line will show values to the left of -1 with an open circle at -1.

Step-by-step explanation:

To solve the inequality 1 - 2x > 3, follow these steps:

1. Subtract 1 from both sides to get -2x > 2.
2. Divide both sides by -2 remembering that dividing by a negative number reverses the inequality, to get x < -1.

The corresponding number line would show all the numbers to the left of -1, with an open circle at -1 indicating that -1 is not part of the solution set.
