Step-by-step explanation:
Answer:
B. -4
Step-by-step explanation:
We want to find x such that f(x)=18.
We need to therefore solve 9x+54=18 forx.
9x+54=18
Divide both sides by 9:
(9x+54)/9=18/9
9x/9+54/9=18/9
Simplify:
x+6=2
Subtract 6 on both sides:
x=2-6
Simplify
x=-4.
So f(-4) should have value 18.
Let's check.
f(x)=9x+54
f(-4)=9(-4)+54
f(-4)=-36+54
f(-4)=18
So the answer is B.
Answer:
D. The data are discrete because the data can only take on specific values.
Step-by-step explanation:
<u>Continuous variables</u> are variables that can take on any value in an interval. Examples of continuous variables are length, time, etc.
<u>Discrete variables</u> on the other hand are variables that can only take on specific values.
The durations of movies in minutes<u> can only take on integer values from 0 to 60.</u> Therefore, it is a discrete data.
The correct option is D.
<span>All real numbers that are greater than –6 but less than 6 is written as -6 < x < 6</span>
