How do you solve and graph #-6 <3x + 2 < 11#?

Answer 1

# -2 2/3 < x < 3#

It is easier to solve a double inequality by splitting it into 2 inequalities. Thus, we will split up and solve the given #-6 < 3x+2 < 11# as #{: (-6 < 3x + 2,,3x+2 < 11), (rarr-8 < 3x,,rarr3x < 9), (rarr -2 2/3 < x,,rarr x < 3) :}#

This can be plotted on a number line as shown in the Answer (above); notice the hollow circles which indicate the those values are not included in the solution.,

Answer 3

To solve and graph the compound inequality ( -6 < 3x + 2 < 11 ):

  1. Subtract 2 from all parts of the compound inequality:

[ -6 - 2 < 3x + 2 - 2 < 11 - 2 ]

This simplifies to:

[ -8 < 3x < 9 ]

  1. Divide all parts of the compound inequality by 3:

[ \frac{-8}{3} < \frac{3x}{3} < \frac{9}{3} ]

This simplifies to:

[ \frac{-8}{3} < x < 3 ]

So, the solution to the compound inequality is ( \frac{-8}{3} < x < 3 ).

To graph this on a number line, plot an open circle at ( x = \frac{-8}{3} ) and at ( x = 3 ), indicating that the endpoints are not included in the solution. Then, shade the region between these two points, indicating that all values of ( x ) within this interval satisfy the compound inequality.

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.
