Point A before being rotated = (1,-2)
A point (x,y) is rotated counterclockwise by 90°. The result will be (-y,x)
If point (1,-2) rotated counterclockwise by 90°, the result will be (2,1)
ANSWER: A. (2,1)
Answer:
This conjecture is false
<u> Explanation:</u>
A Conjecture is only an educated guess which might or might not be true. When two angles are supplementary, it means their sum when added together is 180°. But as per this, conjecture both the angles are acute, which means both are less than 90°. This is not possible.
This can be explained with a counter example. It is an example that can be given to show that a particular conditional statement is false.
If both angles are acute means they are less than 90°.Like one angle is 80° and the other is 70°. Adding 80° and 70° we will get 150°, which is not supplementary.
9 is your answer. When you have a negative squared number, your answer will be positive. Think of it like -3*-3.

Answer:
p > 0
Step-by-step explanation:
x² = p
x² - p = 0
A = 1, B = 0, C = -p
For 2 real roots:
B² - 4AC > 0
0² - 4(1)(-p) > 0
4p > 0
p > 0
