Solve the following absolute value inequality graphically: |x|-3>1.
Dovator [93]

Answer:

  x < -4 ∪ x > 4

Step-by-step explanation:

The absolute value function is shifted down 3 units. The solution space is values of x where y = |x|-3 is greater than 1. The solution is shown in red in the attachments, and the left and right (dashed) sides of the inequality are shown in blue.

__

I personally prefer to rewrite the inequality so the comparison is to <em>zero</em>. That is done in the second attachment, which rewrites it to ...

  |x| -4 > 0

by subtracting 1 from both sides. It is often easier to read the values of x-intercepts than it is to read the coordinate values where lines cross each other.

Are these triangles similar? if so, what postulate or theorem justifies that they are similar?
Karo-lina-s [1.5K]

Answer:

Yes The triangles are similar by SAS Similarity Theorem

Step-by-step explanation:

we know that

<u>Side-Angle-Side Similarity,</u> states that If an angle of a triangle is congruent to an angle of another triangle and if the included sides of these angles are proportional, then the two triangles are similar

In this problem

Angle  L is congruent with Angle Z

so

Verify if the included sides are proportional

so

\frac{LJ}{ZY}=\frac{KL}{XZ}

substitute the values

\frac{3}{1.5}=\frac{4}{2}

2=2 -----> is true

therefore

The triangles are similar by SAS
