Answer:
It would be 80 percent. 150/5 equals 30. 30x4=120 so there is your points. Each 30 is 20 percent. so 20x4=80

m=D x V
or M=DV
first step is to cross multiply so that M can stand alone
With u = <-7, 6> and v = <-4, 17>, we have
u + 3v = <-7, 6> + 3 <-4, 17> = <-7, 6> + <-12, 51> = <-19, 57>
We want to find a vector w such that
u + 3v + w = <1, 0>
Subtract u + 3v from both sides to get
w = <1, 0> - (u + 3v) = <1, 0> - <-19, 57>
w = <20, -57>
