Answer:
(D)
Step-by-step explanation:
Given the absolute inequality:
When solving absolute inequalities, if the problem has a greater than sign we set up an "<u>OR" compound inequality</u> that looks like this:
Therefore, for the absolute inequality |3x+2| >7, we have:
The correct option is D.
Answer:
Increasing
Step-by-step explanation:
Let's see what happens if we choose a value for b greater than 1.
Let's try b=2.
.
I'm going to keep increasing x. If y increases, the the function is increasing. If y decreases, the function is decreasing.
Let's start with x=1.
Now x=2.
The y's got higher as you increased x so the function is increasing.
Answer:
AC ≈ 17.3 , BC ≈ 5.3
Step-by-step explanation:
using the tangent ratio in right triangle ACD
tan51° = =
=
( multiply both sides by 14 )
14 × tan51° = AC , then
AC ≈ 17.3 ( to the nearest tenth )
using the cosine ratio in right triangle ABC
cos72° = =
=
( multiply both sides by 17.3 )
17.3 × cos72° = BC , then
BC ≈ 5.3 ( to the nearest tenth )
