How would you explain to a seventh grader the difference between the domains of an odd root radical function and an even root radical function?

To start with, when you multiply an even number of negative numbers, the answer is positive. When you multiply an odd number of negative numbers, the answer is negative. When you multiply any number of positive numbers, the answer is always positive. For positive numbers, the value of a power is always positive. For negative numbers, the value of an odd power is negative, and the value of an even power is positive. Finding roots is the inverse of taking powers, so that an odd-root function can be evaluated for any value of x. An even-root function, however, cannot be evaluated when the value of x is negative, since an even power can never result in a negative answer. The domain of an odd root function is all real numbers; the domain of an even root function is the non-negative real numbers.


Can you show on a number line how subtracting a negative number ends up positive?

-3...-2...-1...0...1...2...3To find the positive number when subtracting from a (-)number is finding the Absolute Value of the sum. Another way is changing the negative number to a positive and reversing the equation.*Such as, 1-(-3)--> +3-1. So than the answer is a positive 4.* Dots represent the actual line

How do you you reduce a fraction with a negative number as a numerator?

Reduce it as you would normally, negative fractions are no different to positive fractions. Also, it doesn't matter which of the numerator or denominator are negative, as long as when it is reduced the fraction is negative overall.

How do you know when the slope of a line is negative?

You know when the slope of a line is negative when m in the slope-intercept form equation y=mx+b is negative. For example, y=-3x+2 has a negative slope since m (which is -3 in this case) is negative. This is the same when finding a positive slope, because if m is positive, then the slope is positive.


Are crystals in the urine negative or positive?

Crystals in the urine can be both negative and positive. Often, they are considered a negative finding as they may indicate underlying issues such as dehydration, diet imbalances, or certain medical conditions. However, crystals can also be a normal finding and not cause for concern in some cases.


What are the positive and negative referred to?

When used with numbers, positive means "more than zero", and negative means "less than zero". Other meanings are:* Positive: something favorable; negative: something unfavorable. * Positive: something is found; negative: nothing was found. Especially used for medical analysis. Note that this meaning is quite contrary to the previous one - since finding a disease can be quite unfavorable for the patient!

How do you find the greatest common factor of a positive and negative number?

Well, to get a negative number, when multiplying, you must have a negative and a posative. Therefore their would be one negative and posative solution, which would allow you to find a GCF for both a posative and negative number. Here's and example: Find the GCF of 4, and -12 You would factor each of them : you would have 4: 2,2 1,4 -12: 6,-2 2,-6 12,-1 .12,1 3,-4 4,-3 You would then determine that using that data, 4 would be the greatest common facotr of those two numbers.


Can you find an answer to a question you do not know?

The answer to any question must be positive or negative. Therefore one has a 50-50 chance of finding the correct answer to a question one does not know. By presenting a positive or negative answer at random to the unknown question, one has an edge over finding the unknown question. By using the given answer as a guide the question, in question, will arrive momentarily consequential to some thought regarding the answer that has no question, Simple!!


What is negative 3 plus positive 8?

When adding negative 3 and positive 8, we can think of it as moving 3 units to the left on the number line and then moving 8 units to the right. The net result is moving 5 units to the right. Therefore, negative 3 plus positive 8 is equal to positive 5.
