Write an inequality using absolute value if the answer is given double inequality

-2 is less than x and less than 4

Step-by-step explanation:

You are given

Note that

so, first, subtract 1 from this double inequality:

Now, rewrite it using absolute value:

Meaning: point x is less than 3 units away from point 1.

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
