The absolute value
returns the "positive version" of a number.
In other words, if the number is positive, it remains positive; if the number is negative, it changes sign.
So, if we want
, we want the "positive version" of x to be 9.
This can happen in two ways: if x is already 9, then its absolute value is still nine. If instead x=-9, its positive value will be 9 again.
In formula, we have

because

Answer:
<u>
</u>
Step-by-step explanation:
For the standard form equation to model the values in the table, each value of x in the table should give the matching the y value when substituted into the equation. We will test each equation:
<u>
for (-2,4)</u>

This does not give 4 as the answer and is not a solution.
<u>
for (-2,4)</u>

This does give 4 as the answer and is a possible solution.
<u>

Answer:
Answer is 25/56
Step-by-step explanation:
Given that
Katie and her brother are both writing a report. Katie write 7/8 of her report and her brother wrote 3/7 of his report
TO compare these two fractions we have to make both of them have the same denominator.
We find that as such the two fractions have denominators as 7 and 8 and hence Least common multiple is 56
LEt us make equivalent fractions
7/8 = 49/56
3/7=24/56
Difference i.e. Katie wrote more than her brother = 49/56-24/56
=25/56
Answer:
answer is 18.76 percent.
Step-by-step explanation:
CP= $40
SP= $32.5
Markdown percent=?
now,
markdown %= CP-Sp/CP×100%
=7.5/40×100%
=750/40
=18.75%
