If I remember correctly this is how you solve it.

f(x)=8x+6
f(-1)=8(-1)+6
f(-1)=-8+6
f(-1)= -2

F(x) = 8x + 6

To find f(-1), substitute x = -1 :

f(-1) = 8(-1) + 6 = -8 + 6 = -2

Answer: f(-1) = -2

Determine whether the vectors u and v are parallel, orthogonal, or neither. u = <6, -2>, v = <8, 24>

ratelena [41]

We'll check if they're orthogonal:
u*v=0
(6,-2)*(8,24)=0
6*8+(-2)*24=0
48-48=0
0=0
they are orthogonal vectors

Sam wants to find the best buy on cans of tuna. He reads these four ads in the newspaper.$12.53 for seven cans$5.97 for three ca

grandymaker [24]

In each case divide the price by the number of cans.
The best buy is the lowest price.
$12.53/7 = $1.79
$5.97/3 = $1.99
$7.95/5 = $1.59
$8.34/6 = $1.39

The fourth ad, $8.34 for 6 cans results in the lowest price per can, $1.39.
The fourth ad is the best buy.
