Answer:
PROOF:
Suppose that A is an invertible non singular matrix.
Then,

This shows that if A is non singular invertible matrix ad if λ is eigenvalue of A then λ⁻¹ is eigenvalue of A⁻¹.
Put me as brainliest ive tried i cant figure it out plzz
Answer:
Step-by-step explanation:
the 4 one
Answer:
(3x+5y)/8
Step-by-step explanation:
The total amount is 150+250=400
We then do (3x+5y)/2 × 1/400
This equals (3x+5y)/800
We multiply that by 100 giving us the final answer.
Answer:
y = -1/2x +1
Step-by-step explanation:
The y intercept is 1 (this is where it crosses the y intercept)
(0,1) and (2,0) are two points on the line
The slope is given by
m = (y2-y1)/(x2-x1)
= (0-1)/(2-0)
= -1/2
The slope is -1/2
The slope intercept form is y = mx+b where m is the slope and b is the y intercept
y = -1/2x +1
