Let u = < -5, -3> , v = < -6, -1> . find -3u + 5v. < 45, 14> < -15, 4> < 33, 12> < -15, -4>

<-15, 4>

Step-by-step explanation:

-3u + 5v

-3(<-5, -3>)+5(<-6, -1>)

<15, 9> + <-30, -5>)

<-15, 4>

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
