If "one number" is negative and "another" is positive and the absolute values are the same, then "one number" will be less (because it is negative) than "another" (because it is positive).
All negative numbers are less than any positive numbers.
The absolute value of the sum of two complex numbers is less than or equal to the sum of their absolute values.
When comparing negative numbers or a negative number and a positive number, the word "smaller" is confusing because it is unclear whether you mean that the number is less than another number or that the absolute value of the number is less than the absolute value of another number. You should use the phrase "less than" instead. A number's absolute value is how far it is from zero; for negative numbers think of it as the number without the negative sign. Negative eleven is less than negative three because negative eleven is farther left on the number line, but the absolute value of negative three, which is shown as |-3|, is less than the absolute value of negative eleven because negative three is closer to zero.
A negative number is less than its absolute value.
I think your teacher made a mistake on your paper, this is impossible without considering negatives and absolute values.
No, it is not true that no negative number is less than its absolute value. In fact, all negative numbers are less than their absolute value. The absolute value of a negative number is always positive.
negative
No it is not true. The absolute value of a number is simply the value of the number with a positive sign.
True, every positive number is equal to its absolute value. Every negative number will be smaller than its absolute value.
Do you mean 3 + 4|3x + 7| ≤ - 89? There is no solution to the inequality, since it is a false statement. A positive number cannot be equal or less than a negative number. On the left side, you are dealing only with positive numbers, since the absolute value is always positive, no matter what the values of x are.
Not sure what "this" is, but the conclusion is false.
NO! abs(2-2)=0 NOT equal to abs(2)+abs(-2)=4 - The above is technically correct, though the more thorough answer is as follows; no because the absolute value of the sum is LESS THEN OR EQUAL TO the sum of the absolute values. The simple proof the the fact that |A+B|<=|A|+|B| is called the triangular inequality. When A and B (or for that matter an infinite number of them) are both positive (or all) or both negative (or all) then they inequality is actually equal, if however any of the numbers have different signs then any other number, the inequality is less then.
no it can notAnother AnswerThis is not true. Every positive number is equal to its absolute value. Every negative number will be smaller than its absolute value.
