All you have to do is times it by 4
Answer:
The car uses less gas
They use the same amount of gas after miles
Step-by-step explanation:
Given
The table represents the car mileage
--- The van
First, calculate the car's slope (m)
From the table, we have:
So, we have:
Calculate the equation using:
implies that for every mile traveled, the car uses 1/40 gallon of gas
Also:
--- The van
By comparison to:
This implies that for every mile traveled, the van uses 1/5 gallon of gas.
By comparison:
This means that the car uses less gas
Solving (b): Distance traveled for them to use the same amount of gas.
We have:
--- The van
--- The car
Equate both

Take LCM
Solve for -7x
Solve for x
Your f(x)=sqrt[x+8]/(x+4)(x-6) is MUCH clearer, but not 100% clear. I will assume that your denominator here is the product of (x+4) and (x-6):
√x+8)
f(x) = ------------------
(x+4)(x-6)
We cannot divide by zero. Thus, x cannot be -4 and cannot be 6.
Thus, the domain is:
(-infinity, -4) or (-4, 6) or (6, infinity).

Answer:
Mean = 30.3
Median = 30
They scored 30 or more points on 11 games.
Step-by-step explanation:
Mean = all the numbers added together divided by 21
636/21 = 30.3
Median is the middle number (the 11th) = 30
