Answer:
x= -3 and y= 0
Step-by-step explanation:
5x+2y=-15
<u>2x-2y=-6 </u>
<u>7x =-21</u>
x= -3
Putting value of x in equation 1
5(-3) +2y=-15
-15+2y= -15
2y= 0
y= 0
This can be solved with the help of matrices
In matrix form the above equations can be written in the form
=
Let
= A
= X and
= B
Then AX= B
or X= A⁻¹ B
where A⁻¹= adj A/ ║A║ where mod A≠ 0
adj A=
║A║= ( 5*-2- 2*2)= -10-4= -14≠0
X= A⁻¹ B
=- 1/14
=- 1/14
=- 1/14
=- 1/14
=
=
From here x= -3 and y= 0
Solution Set = [(-3,0)]
Answer:
Edward drove altogether of 16.1 miles.
Step-by-step explanation:
Given:
Edward was Running around on his bike.
Distance from home to post office =
can be Rewritten as
Distance from home to post office =
Now Given:
Distance from Post office to market = 3.25 miles.
Now we will calculate Distance from Home to market.
Distance from Home to market can be calculated by adding Distance from home to post office and Distance from Post office to market.
Framing in equation form we get;
Distance from Home to market =
Also Given:
his mother picked him up at the market and drove him home.
We need to find the total miles Edward drive altogether.
total miles Edward drive altogether will be equal to Sum of Distance from Home to market and Distance from market to home.
framing in equation form we get;
Total Distance Edward drove =
Hence Edward drove altogether of 16.1 miles.
