What is the first step in evaluating an absolute value expression?

See below.

Step-by-step explanation:

As per definition:

and

So when we evaluate an expression with absolute value the first step is to simplify what is within absolute value symbols.

The next step to get the quantity of it and if positive number just cancel absolute value symbols or replace it with parenthesis; if negative, then cancel absolute value symbols, replace it with parenthesis and add negative sign.

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
