Question

On the radio one morning, a weather reporter stated that the tempature was two degrees below zero, but the tempature would cotinue to rise throughout the day. Which inequality can be used to represent readings, T, that day? A. T < -2 B. T < -2 ( _ UNDER < ) C. T > - 2 D. T > -2 ( _ UNDER >)

Answer 1

T ≥ -2

Explanation:

Given

Temperature = 2° below 0°

Required

Represent as an inequality

First, we need to calculate the temperature in the morning.

2° below 0 means.

Temperature = 0° - 2°

Temperature = -2°

Next, we determine the temperature at any time.

The question says the temperature continues to rise during the day.

Represent this with T

This means T will be greater than -2°

However, we need to consider where the temperature started from.

In other words, T = -2

Combine T = -2 and T = -2 together, we have:.

T ≥ -2

Hence, the inequality that represents the scenario is T ≥ -2
