The answer is A. L*W which 4 by 6
Answer:
If AB = BA = I, then B is inverse of A and vice-versa.
Step-by-step explanation:
Given: AB = BA = I
To find: The relation between matrix A and B.
If AB = BA = I, then B is called the inverse matrix of A and is denoted by
.
In that case, A is said to be invertible.
Also, if B is the inverse of A, then A is also the inverse of B.
Hence, the relation between A and B is that both are inverse of each other.

Answer:
4. True
5. False
Step-by-step explanation:
4. The number of x-intercepts produced by the quadratic formula may be 0, 1, or 2. It will be 0 if the two roots are complex. It will be 1 if the two roots lie in the same place (one root with multiplicity 2). It is true that there may be only one x-intercept.

Answer:
y =

x + 4
Explanation:
The equation of the lone has a general formula:
y = mx + c
where:
m is the slope of the line = 1/6
c is the y-intercept = 4
Substitute with the givens in the above formula to get the equation as follows:
y = mx + c
y =

x + 4
Hope this helps :)
