Solve and write in interval notation. x ≥ 2 and x < -3

hoa [83]3 years ago

Think:  all values of x = to or > than 2 are ok, as are all values of x smaller than -3.

The first inequality, graphed, looks like "a solid dot at x = 2" and an arrow pointing to the right from that dot, plus an open circle at x = -3 and an arrow pointing to the left from that circle.  These two arrows have NO overlap, so there is no "solution."

If you want the problem in interval notation, it's  (-infinity, -3) ∪ [2, infinity).

Write an equation of each line in standard form with integer coefficients.<br> 4. y = 2.4x + 1.8
Nadusha1986 [10]

Answer:

<h2>12x - 20y = -9</h2>

Step-by-step explanation:

The standard form of an equation of a line:

Ax+By=C

We have

4y=2.4x+1.8

Convert

4y=2.4x+1.8          <em>multiply both sides by 10</em>

40y=24x+18          <em>subtract 24x from both sides</em>

-24x+40y=18            <em>change the signs</em>

24x-40y=-18          <em>divide both sides by 2</em>

12x-20y=-9
