Sajia can sell 21 books she can sell if she comes back on sunday and the required inequality is
Solution:
Given that Sajia has 30 Books in her library
She sold 9 books at the thrift store on Saturday
To find: We have to write and solve an inequality to determine number of more books she can sell if she comes back on sunday
Let "x" be the number of more books she can sell if she comes back on sunday
We can write a inequality as:
Now moving 9 from L.H.S to R.H.S we get,
On solving 30 - 9 = 21,
So Sajia can sell 21 books she can sell if she comes back on sunday
The sum of the vectors is (2,1)
A vector exists as an object that has both a magnitude and a direction. Geometrically, we can imagine a vector as a directed line segment, whose length exists the magnitude of the vector and with an arrow suggesting the direction. The direction of the vector exists from its tail to its head.
(-1,-4) + (3,5)
( -1+3 , -4+5 )
( 2,1)
