How do you solve #6r<-36# and graph the solution on a number line?

Answer 1

Savannah Anderson

#r < -6#

graph:
open circle and a ray line from -6 to the left.

divide both sides just like normal equality and keep the sign.

To solve the inequality 6r < -36, first divide both sides by 6:

r < -6

Now, to graph the solution on a number line, draw an open circle at -6 to represent that the value of r is not included, and shade to the left of -6 to represent all values of r less than -6.

Answer from HIX Tutor

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.
