Answer:
B
Step-by-step explanation:
Any inversely proportional equation is of the form y=k/x.
16r^2+ 2r -4r
16r^2 - 2r
2r ( 8r -1)
Answer:
x is in the range [-1,4]
Step-by-step explanation:
I haven't worked with absolute value inequalities in awhile, but let's take a wack at this.
We are given the following inequality:
| 2x - 3 | <= 5
This implies two possible cases:
[1] -5 <= 2x -3
Or
[2] 2x - 3 <= 5
So let's solve x for both of these cases:
[1] -5 <= 2x - 3
-2 <= 2x
-1 <= x
[2] 2x - 3 <= 5
2x <= 8
x <= 4
So from these cases, we can say the following is true:
x >= -1 and x <= 4
Thus, we can write this in the form
-1 <= x <= 4
Or in interval notation:
{ x is element of reals | -1 <= x <= 4}
Also written as
x is in the range [-1,4]
Where the closed brackets represent 1 and 4 as possible answers whereas parenthesis would imply they were not.

20 raise the power 7
Step-by-step explanation:
Which clearly means 20 × itself 7 times
Answer:
Outliers affect the mean value of the data but have little effect on the median or mode of a given set of data.
Is there any more details, I could give a better answer.
