Answer:
Step-by-step explanation:
For two matrix P and Q, the product, say PQ is defined when:
The number of columns of P = The number of rows of Q
Since A is a 2×2 matrix and B is also a 2×2 matrix
Thus both AB and BA are possible.
So AB is:
BA is:
Answer:
one line that is parallel to this equation is, y=5/7x-6.
Answer:
B
Step-by-step explanation:
If you switch the x and y you can solve for the inverse by solving for y like this:
x=3y+5
3y=x-5
y=(x-5)/3
which can be rewritten as B.
Answer:
1.5
Step-by-step explanation:
Let the unknown number be x.
12 - 5x = 3x
12 = 3x + 5x = 8x
. : x = 12/8 = 3/2 = 1.5
