Find a subset of the vectors that form a basis for the span of the vectors; then express each vector not in the basis as a linear combination of the basis vectors.
v1 = (1,1,-1,2), v2 = (1,-1,1,1), v3 = (3,-5,5,2), v4 = (6,2,-3,8), v5 = (8,2,-4,9)

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
