This involves quite a lot of arithmetic to do manually.
The first thing you do is to make the first number in row 2 = to 0.
This is done by R2 = -3/2 R1 + R2
so the matrix becomes
( 2 1 1) ( -3 )
( 0 -13/2 3/2) (1/2 )
(5 -1 2) (-2)
Next step is to make the 5 in row 5 = 0
then the -1 must become zero
You aim for the form
( 1 0 0) (x)
(0 1 0) (y)
(0 0 1) ( z)
x , y and z will be the required solutions.
A centimetre is the most appropriate unit
Answer:
Slope is 1/2
Step-by-step explanation:
Slope Formula = m = y2 - y1/x2 - x1
Point = (4,2) and (10,5)
m = y2 - y1/x2 - x1
m = 5 - 2/10 - 4
m = 3/6
m = 1/2

Answer:
The answer would be 2:30
Step-by-step explanation: lets say they both take 3 hours, that would mean that if they work together, that means they can cut their time by half,
but if jai is slower paced it and takes about 1 hour more, just add 1 hour to the hour and 30 to be able to get 2:30
pls give brainliest.
