Is anyone good with triangle inequalities? I provided a picture for the problem.
alisha [4.7K]

Answer:

1 < x < 19

Step-by-step explanation:

Triangle Inequality Theorem

Let y and z be two of the side lengths of a triangle. The length of the third side x cannot be any number. It must satisfy all the following restrictions:

x + y > z

x + z > y

y + z > x

Combining the above inequalities, and provided y>z, the third size must satisfy:

y - z < x < y + z

We are given the measures y=10, z=9. The third side must satisfy:

10 - 9 < x < 10 + 9

1 < x < 19

Which of the following sets would have a graph with an open circle on 2 and a ray pointing left on the number line?
andreyandreev [35.5K]

Answer:

{x | x∈ R, x < 2}

Step-by-step explanation:

Given

Open circle on 2

Arrow pointing left

Required

Determine the inequality

An open circle on 2 means represents either < or >

The arrow points to the left of -2 means that the number line represents numbers less than 2. i.e. < 2

Represent the numbers with x.

The inequality is: x < -2

Using proper notation, the inequality is:  {x | x∈ R, x < 2}
