Answer:
B)
Step-by-step explanation:
If two square matrix, with same dimensions, are inverse of one another, their product will always be the identity matrix with the same dimensions.
The matrix A and B are 2x2, so the result of the product A * B is a 2x2 identity matrix, that is represented as follows:
I = [1 0 ; 0 1]
(First line: 1 0, second line: 0 1)
So the correct option is B)
Answer:
<h2>25</h2>
Step-by-step explanation:
So there is this property,
Sum of two angle of triangle = exterior angle
So based on this we can form an algebraic equation (NOTE: this is an equilateral triangle so all the sides are 60°)

So it's option B.
AC # A'B'
Step-by-step explanation:
While solving the above problem one must keep in mind that
- Reflection along Y-axis would just make the rectangle upside down at the same distance from X-axis in the down direction.
Thus, from the figure it becomes clear that
- AB ∦ B’D’
- CD║A’B’
- BD ∦ C’D’
Only statement that comes out true is the third statement which states that AC is not parallel to A’B’
Since the diagonal of a rectangle can not be parallel to one of its side (though the side in question is side of the same rectangle reflected in y axis)
Answer:
You reflected in the y axis in stead of the x axis.
The reflected coordinates are:
(2,4), (3, -7) and (6,1)
The mirrored triangle will overlap with the original one.
3 1/3 is the solution. Solve by substituting the variables first.
