Answer:
A
Step-by-step explanation:
To answer this, look at one specific point for example, A. It is at the point (3,6). In order for this point to get to where it was moved to, you must rotate it counterclockwise () 90 degrees. Do this by changing the initial point from (x,y) to (-y,x). This is located at (-6,3). Then you can see that it was translated 2 units up from there.
I hope this helped.
C.
not sure, goodluck. sorry if it’s wrong:)
Answer:
Option D. two complex roots
Step-by-step explanation:
we know that
In a quadratic equation of the form 
the discriminant D is equal to
in this problem we have
so
substitute the values
The discriminant is negative
therefore
The quadratic equation has two complex roots
Answer:
A. y >= 0
Step-by-step explanation:
The range of a function is the set of all values that the y-coordinate can have.
Look at the graph. Look at the red curve. The lowest y-coordinate is 0. As the curve goes up to the right, the y-coordinates are all real numbers greater than or equal to 0.
Answer: A. y >= 0
Answer:
x = 52
The exterior angle of a triangle is equal to the sum of the opposite interior angles
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the opposite interior angles
x+72 = 90+34
Combine like terms
x+72 = 124
Subtract 72 from each side using the subtraction property of equality
x+72-72 = 124 -72
x =52
