That is false. A negative times a negative is always a positive. Since absolute numbers are always positive if you make it negative that is not correct.
No. You have it backwards . . . . . the absolute value of a negative number is always a positive number.
Other than for the value 0, there are always two numbers that have the same absolute value: the number and the negative of the number, eg 2 and -2 both have the absolute value 2. There is no negative 0, so there is only the number 0 which has the absolute value 0.
Not sure what "this" is, but the conclusion is false.
true (that's the whole point of absolute value)
It is false because if it is the absolute value of a negative number, the answer would be higher than the original number. |-9|=9
It is true. Look at absolute value as a number's distance from zero, and distance can't be negative. Take, say, -7. -7 is 7 away from 0, so the absolute value of -7 is 7.
Is false. If ' n ' is negative, then ' -n ' is positive.
No.A positive integer is always larger than a negative integer. In the case of two negative integers, the integer with the larger absolute value is actually smaller.
That statement is false. For example, (-2) - (-3) = 1 which is a positive number created from two negative numbers when subtracted.
That is false. The product of two negative integers is always positive.
False. The product of an odd number of negatives is negative.
yes the answer is always a positive
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.
False. Counterexample: -1 - (-2) = -1 + 2 = 1.
