The rate that is equivalent is 42 miles over 3 gallons
42/3=14
14:1=14 42/3=14
Answer:
D
Step-by-step explanation:
1. Add the costs together 10.98+13.95+22.56=47.49
2. To get an average, divide by the amount of numbers you added together. We added 3 numbers together (10.98+13.95+22.56) so we divide by 3.
47.49/3=15.83
The option closest to our number is D so we round up.
$15.83->$20
Have a good day.
Answer:
a. The function is increasing when
and decreasing when
.
b. The function is greater than zero when
and ![x>5](https://tex.z-dn.net/?f=x%3E5)
c. The function is less than zero when ![3](https://tex.z-dn.net/?f=3%3Cx%3C5)
Step-by-step explanation:
a. The function
is increasing when it's instantaneous slope ( the slope of the line tangent to the graph ) is positive, and it is decreasing when the instantaneous slope is negative. We see from the graph of
that for
the instantaneous slope is positive, and for
the slope is negative.
b. From the graph we see that the function is greater the zero (has positive values ) when
and
.
c. The graph of the function is less than zero ( is negative) when ![3](https://tex.z-dn.net/?f=3%3Cx%3C5.)
The LCM of 3 is 12 because 12 is the smallest number that 3 and 4 are both factors for .
I hope that's help !
