Evaluate the expression. r = <5, 9, -4>, v = <3, 3, -8>, w = <9, -6, -1>
v ⋅ w
Options:
<-15, -27, -32>
0
17
<27, -18, 8>

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

hi how are you doing today, if you need just ask me.

step-by-step explanation:

they would have to work 32 hours.

x-150=475   x=625
