How do i do this ???
Westkost [7]

a peculiar thing about the centroid of a triangle, is that it cuts all the medians in a 2:1 ratio, so JP : PM are on a 2:1 ratio, thus

\bf JP:PM\qquad 2:1\qquad \cfrac{JP}{PM}=\cfrac{2}{1}\implies \cfrac{27}{PM}=\cfrac{2}{1}\implies \cfrac{27}{2}=PM\\\\-------------------------------\\\\JM=JP+PM\implies JM=27+\cfrac{27}{2}\implies JM=\cfrac{54+27}{2}\\\\\\JM=\cfrac{81}{2}\implies JM=40\frac{1}{2}

What is the solution set for the inequality x &lt; -2 or x &gt; 6
bija089 [108]

he solution set is

{ x ∣ x > 1 } .


Explanation

For each of these inequalities, there will be a set of

x

-values that make them true. For example, it's pretty clear that large values of

x

(like 1,000) work for both, and negative values (like -1,000) will not work for either.

Since we're asked to solve a "this OR that" pair of inequalities, what we'd like to know are all the

x

-values that will work for at least one of them. To do this, we solve both inequalities for

x

, and then overlap the two solution set
