Answer with Step-by-step explanation:
Suppose that a matrix has two inverses B and C
It is given that AB=I and AC=I
We have to prove that Inverse of matrix is unique
It means B=C
We know that
B=BI where I is identity matrix of any order in which number of rows is equal to number of columns of matrix B.
B=B(AC)
B=(BA)C
Using associative property of matrix
A (BC)=(AB)C
B=IC
Using BA=I
We know that C=IC
Therefore, B=C
Hence, Matrix A has unique inverse .

Hope It helps you :) Cause the graph haves to show two unsame activities
Step-by-step explanation:
Answer:
y = 7x - 17
Step-by-step explanation:
If you graph the coordinate (3,4) and then apply the slope (7 up / 1 down) , you will end up passing through the point (0,-17) on the y line. The point the line passes on the y line would be the y intercept.
Once you have all the necessary information, you put it into a y=mx+b form. m being the rate or slope, and b being the y-intercept.
Answer:
angle ABC is 48⁰
Step-by-step explanation:
angle BCD will be 111⁰ it will be equal to DAB.
111+111+90=312⁰
kite is a quadrilateral so its angles add up to 360⁰
360-312=48⁰
A
B
C
D
multiply them by 6 and add 3.5 to your answer and youll get the right one
