If
is invertible, then we can simply choose
because for any invertible matrix
by definition we must have
.
We have
, as
which means
is non-singular and has an inverse. The inverse itself would be
Answer: The answer would be D.
Step-by-step explanation: (4x+3)(2x−1)
So if 7 is the middle x-value, you calculate how far it is from the given endpoint in order to determine how far it is from the other endpoint. So,
7 -5 =2, so the other endpoint must be 2 away from 7 in the opposite direction, 7+2=9
Then repeat with y,
3-1/2=5/2, therefore 1/2 - 5/2 = -4/2= -2
So the point is (9, -2)
Answer:
x = {-4, 4}
Step-by-step explanation:
Subtracting 3 gives ...
5x^2 = 80
Dividing by 5, we get ...
x^2 = 16
Taking the square root gives the solutions ...
x = ±4
The smaller value of x is -4; the larger value is 4.
