Determine
whether b can be written as a linear
combination of a1 and a2. in other words, determine
whether weights x1 and x2 exist, such that x1a1 + x2a2 = b. determine the
weights x1 and x2 if possible.
a1[4,5,-4]
a2[-4,3,3] b,[8,26,-10]

Linear Combination Of Vectors

One vector is a linear combination of and if there are two scalars such as

In our case, all the vectors are given in but there are only two possible components for the linear combination. This indicates that only two conditions can be used to determine both scalars, and the other condition must be satisfied once the scalars are found.

We have

We set the equation

Multiplying both scalars by the vectors

Equating each coordinate, we get

Adding the first and the third equations:

Replacing in the first equation

We must test if those values make the second equation become an identity

The second equation complies with the values of and , so the solution is

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
