The answer is C because if you put
![x = - 2 \\ y = 1 \\](https://tex.z-dn.net/?f=x%20%3D%20%20-%202%20%5C%5C%20y%20%3D%201%20%5C%5C%20)
Find the reflected two points which are:
![x = 1 \\ y = - 2](https://tex.z-dn.net/?f=x%20%3D%201%20%5C%5C%20y%20%3D%20%20-%202)
They're just flipped equations
Answer:
30
Step-by-step explanation:
(-) (-) = +
Therefore 15 - (-15) = 15 + 15 = 30
Answer:
4
Step-by-step explanation:
the figures are
0,0,3,8,1,0
we repeat 0
so we have 4 figures,
0,3,8,1
Answer:
If using complex numbers, or undefined if using all real numbers
Step-by-step explanation:
Moving -8 to the left side of the eq by adding both sides by 8=
x^2-3x+8=0
The quad formula:![\frac{-b +- \sqrt{b^2-4ac}}{2a}](https://tex.z-dn.net/?f=%5Cfrac%7B-b%20%20%2B-%20%5Csqrt%7Bb%5E2-4ac%7D%7D%7B2a%7D)
a=1 b=-3 c=8
Inserting a b c values into formula: ![\frac{-(-3) +- \sqrt{(-3)^2-4(1)(8)}}{2(1)}](https://tex.z-dn.net/?f=%5Cfrac%7B-%28-3%29%20%20%2B-%20%5Csqrt%7B%28-3%29%5E2-4%281%29%288%29%7D%7D%7B2%281%29%7D)
Simplifying:
Since the square root of a negative number doesn't exist in the set of real numbers, the equation is undefined.
OR
Using complex numbers i, to replace the negative number created by subtracting 9-32.
