Answer:
Using Math.
Step-by-step explanation:
You solve it using math.
See, you should have been more specific with your question, maybe said "What is the answer" not "How do I solve".
But I guess I'll help you out bro
<em>Multiply</em> both sides by 6
that gives you -x>18
then <em>multiply</em> both sides by -1
which means you gotta <u>flip the sign</u>
so final answer is x<-18
Answer:
The range of the function is:
Range R = {14, 17, 20}
Step-by-step explanation:
Given the function
![f(x) = 3x + 2](https://tex.z-dn.net/?f=f%28x%29%20%3D%203x%20%2B%202)
We also know that range is the set of values of the dependent variable for which a function is defined.
In other words,
- Range refers to all the possible sets of output values on the y-axis.
We are given that the domain of the function is:
Domain D = {4, 5, 6}
Now,
substituting x = 4 in the function
f(4) = 3(4) + 2
f(4) = 12 + 2
f(4) = 14
substituting x = 5 in the function
f(5) = 3(5) + 2
f(5) = 15 + 2
f(5) = 17
substituting x = 6 in the function
f(6) = 3(6) + 2
f(6) = 18 + 2
f(6) = 20
Thus, we conclude that:
at x = 4, y = 14
at x = 5, y = 17
at x = 6, y = 20
Thus, the range of the function is:
Range R = {14, 17, 20}
Answer: q = 3
Step-by-step explanation:
Q = (21 - 15)/2 = 6/2 = 3
Answer:
125
Step-by-step explanation:
For number 16 we need to write the data as a ratio then convert to a unit rate (amount per 1)...
308/14 = x/1
Cross multiply
14x = 308
x = 308/14
x = 22
So the fuel efficiency is
22 miles per 1 gallon or
22/1
For number 17, since the car was driven at 48 mph, we just have to divide distance driven by speed to get how long it took...
288 miles ÷ 48 mph =
6 hours
