6 divided by negative 1?
-6 Yes the answer would be -6. But in order to get that answer you must know this: positive divided by a positive = positive positive divided by a negative = a negative negative divided by a positive = a negative negative divided by a negative = positive (also note: it's the same formula for multiplying)
What is the additive inverse of the real number represented by n?
That would be -n. Note that if n is positive, -n is negative, whereas if n is negative, -n will be positive.
Examples for integers?
any negative or positive whole number Ex. -4, 6, -9, 7 Note: No decimals or fractions
How do you multipy two negative fractions?
same as you would multiply 2 normal fractions. Note: a negative times a negative = a positive so - a/b x - c/d = ac/bd e.g -1/2 x - 3/5 = 3/10
Determine in which direction the parabola opens y equals x2-7x plus 18?
A parabola opens upwards if the quadratic coefficient - the number before the "x2" is positive; downward if it is negative. Note that x2 is the same as 1x2.
