10 different pairs. Since there are 5 different brands you simply add 4+3+2+1 to get 10.
(x - a)^2 + (y - b)^2 = r^2 is a circle with centre at (a, b) and radius of r
The correct answer is (x - 2)^2 + (y + 10)^2 = 9 ie the first one
Answer:
C. A reflection over the line y = -x
Step-by-step explanation:
You need to reflect that over a line that goes between the two of them. That imaginary line has a rise of -1 (it goes down 1 unit) and a run of 1 (it goes one unit to the right). In other words, the slope is -1. The line should also have a y-intercept of 0 it starts at (0,0).
Put that information in slope-intercept form
y = -1x + 0
You can take out the 0 because it adds nothing to the equation, and you can remove the one because of the same reason, but leave the negative sign.
y = -x
A modulus is pretty much just the square root of x^2 + y^2, where y is the number that stands with the imaginary “i” and x is the real number. In this case, x is 2 and y is 3, so your modulus would be the square root of 4 + 9 (2^2 + 3^2), or the square root of 13.
