6x^2-x

In order for the left side to be negative, we need either 3x-2>0 and 2x+1, or 3x-2 and 2x+1>0.

  • If 3x-2>0 and 2x+1, then x>\frac23 and x. There is no value of x that meets both conditions, so this case offers no solutions.
  • If 3x-2 and 2x+1>0, then x and x>-\frac12. This means any number x between -1/2 and 2/3 satisfies the inequality.

In interval notation, the solution set is

\boxed{-\dfrac12

How do you find the slope (m) and the y-intercept for (0,-4), (5,-4)?
navik [9.2K]

Answer:

In order to find the slope (m), and the y-intercept of this coordinate pair, you must complete rise over run.

This is represented by y2-y1, x2-x1. This can be represented like so:

-4-0 = -4

5--4 = 9

Here, we have concluded that our slope is -4/9.

Now, we must convert this into point slope form. Point slope form is y-y1=m(x-x1). This will look like this in our situation:

y+4=-4/9(x-0)

To solve, distribute the -4/9 first, which will leave you with:

y+4=-4/9x+0

Now, subract the 4 to both sides of the equation.

Our final answer looks like: y=-4/9-4.

<em>-</em>

<em>SLOPE: -4/9</em>

<em>Y INTERCEPT: -4 </em>
