Answer:
B is the answer because a function is if none of the x values are the same with different y values.
Answer:
45 degrees
Step-by-step explanation:
Think of this web as a circle. This circle is divided into 8 equal pieces.
A circle has 360 degrees in it. If we divide 360 by 8, we get 45. This means that each wedge is 45 degrees, which means that in order to rotate the image to look the same, we must rotate it by 45 degrees.
The answer is -7.4166666 or written as -7.4167
For the general quadratic equation ax^2 + bx + c = 0 the discriminant is b^2 - 4ac.
So, for x^2 + x + 2 = 0, a = 1, b = 1, and c = 2, therefore
b^2 - 4ac = 1^2 - 4(1)(2) = 1 - 8 = - 7.
Answer: - 7
