<span>A zero pair is created when a pair of numbers, one positive and the other negative, equals a sum of zero.The main purpose of a zero pair is to simplify the process of addition and subtraction in complex mathematical equations featuring multiple numbers and variables. For example, in the problem 2+6-3-2, the positive 2 and the negative 2 cancel each other out because they are a zero pair, thus reducing the problem to 6-3.
Examples of Zero Pair:
-9 + 9 = 0</span>
Answer:
4 months.
Step-by-step explanation:
We can write formulas for the amount each person paid after x months. These will be
Brian = 60 + 42.95x
Michael = 0 + 57.95x
So for example, after 1 month Brian will have paid 102.95 for the installation and first month, while Michael will have paid only 57.95 (I put the zero in the equation to make it look like the familiar y-intercept form). We are trying the find the month at which they have paid equal amounts. Solve for x in the equation
60 + 42.95x = 57.95x
60 = (57.95 - 42.95)x
60 = 15x
x = 4
After four months.
Answer:
Step-by-step explanation:
recall for a line whose equation is
y = mx + b,
the slope of this line is m
the slope of a line that is perpendicular to this line is -
in this case,
m = -
hence -=
Answer:
A'(5,-11)
Step-by-step explanation:
Your only changing the y if you are reflecting over the x-axis but change the x if you are reflecting over the y-axis.
