Solve each inequality. Round to the nearest hundredth. 3x2 – 4 ≤ 6 – 5x

Step-by-step explanation:

The first, we will write our inequality in another form:

We want to know when is it equal to 0.

First we solve the equation :

So we want to know when is true. We know, when a>0 function is negative when x is between two zeros. In our example a=3>0. Then we have:

It is true if

i belive those are the ones that are under 90 degreese.
