Answer:
Area of shaded region=41 square feet
Area of non shaded region= 87 square feet
Step-by-step explanation:
As, Shaded area is made of different shapes including two rectangles and one triangle
So,
Area of shaded region,
Area of non shaded region=total area of rectangular region-Shaded region
The equation is a function
Explanation:
Given that the graph contains the coordinates ,
,
and
We need to determine whether the equation is a function.
To determine the equation is a function, let us substitute the coordinates in the equation and check whether it satisfies the equation.
Let us substitute the coordinate in the equation
Thus, we have,
Thus, the coordinate satisfies the equation
Substituting the coordinate in the equation, we have,
Thus, the coordinate satisfies the equation
Substituting the coordinate in the equation
Thus, the coordinate satisfies the equation
Substituting the coordinate in the equation, we get,
Thus, the coordinate satisfies the equation
Hence, the coordinates ,
,
and
satisfies the equation
Thus, the equation is a function.
Answers:
A ' = (-2, -3)
B ' = (0, -3)
C ' = (-1, 1)
=======================================================
Explanation:
To apply an x axis reflection, we simply change the sign of the y coordinate from positive to negative, or vice versa. The x coordinate stays as is.
Algebraically, the reflection rule used can be written as
Applying this rule to the three given points will mean....
The diagram is provided below.
Side note: Any points on the x axis will stay where they are. That isn't the case here, but its for any future problem where it may come up. This only applies to x axis reflections.
