explanations:
1. the opposite of -4 is 4. you can think of this two ways: the opposite of a negative is always absolute value, or the opposite of a negative is always positive.
2. above
3. -5 > -8 because the distance -5 is from 0 is 5, and the distance from -8 to 0 is 8. 8 > 5, so -8 is farther away than -5.
4. while -8 is less than -6, but absolute value would turn -8 into 8, which is greater than -6
5. explained by all above.

First step: Factor the expression.
(x + 8) / (x - 6)(x + 4)
Set each factor of the denominator equal to zero.
x - 6 = 0 x + 4 = 0
add 6 to both sides subtract 4 from both sides
x = 6 x = -4
The function would be undefined if x = 6 or x = -4
Answer:

Step-by-step explanation:
d = Distance to travel = 880 miles
s = Average speed of the car = 65 mph
Time taken to cover the distance is

Time the car stopped

Total time of the journey

Converting
to minutes

So, the total time taken for the journey is 
Time when they reach their destination

Answer: 60
Step-by-step explanation:
Find the total number of students.
In this case, there are 8 total students. Multiply 60 * 8 = 480
Add all the numbers up.
85 + 65 + 36 + 48 + 75 + 39 + 72 = 420
480 - 420 = 60
x = 60
