If f(x) = 3x - 9 and g(x) = -x?, find:
a) f(-2)
b) g(-2)
c.) x if f(x)=0

Step-by-step explanation:

a) f(-2) = 3(-2) - 9 = -15

b) g(-2) = -(-2) = 2

c) 0 = 3x - 9

   9 = 3x

    x = 3

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

the answer is c)8
