Reflection across the y axis means multiply the whole function by -1
so
f(x)=3x+12
times -1
g(x)=-3x-12 is the answer
answer is C
not sure why you put an arrow to choice A, but it's wrong
C is the right answer
Answer:
If a radius of a circle bisects a chord, then it is perpendicular to that chord.
So. A. perpendicular
Answer:
(1 , 6)
Step-by-step explanation:
the center of the circle is the midpoint of the diameter
Which is the point of coordinates:

Then the center is the point :

Answer:

Step-by-step explanation:
All side lengths of a square are equal. The three squares create a right triangle, and the hypotenuse of this triangle represents the side length of the square.
All right triangles must follow the Pythagorean Theorem
where
is the hypotenuse of the triangle.
Therefore, let
be the side length of this largest square. Since the area of a square with side length
is given by
,
will represent the area of the square:

Here BD is perpendicular bisector
So

Apply Pythagorean theorem
