Ameteorologist used the expression below to describe how the temperature changed. –5 + (–4) which statement could describe how the temperature changed? the temperature was –5 degrees, then it increased 4 degrees. the temperature was –5 degrees, then it decreased 4 degrees. the temperature was 5 degrees, then it increased 4 degrees. the temperature was 5 degrees, then it decreased 4 degrees.

The temperature was –5 degrees, then it decreased 4 degrees.

Step-by-step explanation:

Expression :

A meteorologist used this expression to describe how the temperature changed.

Since temperature was -5.

Now,temperature is :

So, initially temperature was - 5 and now the temperature is -9 .

So,it decreased 4 degrees.

Thus we can conclude that The temperature was –5 degrees, then it decreased 4 degrees.

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
