How do you evaluate #a+b+absc# when a=0, b=3 and c=-4?

Answer 1

The answer is #7#.

For any number #c#, the absolute value of #c# (denoted as #abs c#) is simply the distance that number is from #0#. The absolute value of a positive number is simply the number itself. If the number is negative, its absolute value is the number without the negative sign.

Thus, to evaluate #a+b+abs c# when #a=0#, #b=3#, and #c="-4"#, we just plug the numbers in where the matching letters are, and we get

#color(white)= a + b + abs c# #=0 + 3 + abs "-4"# #=0 + 3 + 4# #=7#

So our answer is #7#.

Substitute the given values into the expression: (a+b+absc) with (a=0), (b=3), and (c=-4).

(0 + 3 + (0)(-4) = 3)

Therefore, the value of the expression is 3.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
