How do you graph #-x>=20# on the coordinate plane?

Answer 1

See a solution process below:

First solve for #x# by multiplying each side of the inequality by #color(blue)(-1)#. However, because we are multiplying or dividing an inequality by a negative number we need to reverse the inequality operator:
#color(blue)(-1) xx -x color(red)(<=) color(blue)(-1) xx 20#
#x color(red)(<=) -20#

graph{x + 20 <= 0 [-100, 100, -50, 50]}

The boundary line is a solid line because the inequality operator contains an or equal to clause

To graph the inequality -x ≥ 20 on the coordinate plane, follow these steps:

  1. Start by graphing the line x = -20. This is a vertical line passing through the point (-20,0) on the x-axis.

  2. Since the inequality is -x ≥ 20, the shaded region represents all the points where -x is greater than or equal to 20. This means we shade everything to the left of the line x = -20, including the line itself because it's greater than or equal to 20.

  3. The shading should extend infinitely to the left from the line x = -20, covering all the points where -x is greater than or equal to 20.

That's how you graph the inequality -x ≥ 20 on the coordinate plane.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
