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

Like fractions are fractions with the same denominator. You can add and subtract like fractions easily - simply add or subtract the numerators and write the sum over the common denominator.
Before you can add or subtract fractions with different denominators, you must first find equivalent fractions with the same denominator, like this:
1.Find the smallest multiple (LCM) of both numbers.
2.Rewrite the fractions as equivalent fractions with the LCM as the denominator.
When working with fractions, the LCM is called the least common denominator (LCD)
Answer:
y = -6, perpendicular
Step-by-step explanation:
You can use the points to find the slope of the line:

Then, using point-slope form, choose one set of coordinates to use for y1 and x1:




Since the slope of the line is zero, it's a horizontal line. The y-axis is a vertical line, which means that the line is perpendicular to the y-axis.
I think it can be 605. I'm not sure exactly, but I think it is.
5 = 0.05w
5 / 0.05 = w
100 = w........5 is 5% of 100
