Answer:
1/6
Step-by-step explanation:
P(8) = number of 8's / total = 1/3
Then keeping the card so we have 7 and 9
P(7) = number of 7's / total = 1/2
P(8, keep, 7) = 1/3 * 1/2 = 1/6
Answer:
Step-by-step explanation:
(f - g)(x) = x - 3
Line up these functions vertically:
f(x) = 3x - 2
-g(x) = -(2x + 1)
--------------------
(f - g)(x) = x - 3 (answer)
Answer:
f(x) = 3(x+2)(x-2)
Step-by-step explanation:
We are given a quadratic function and we have to write it in factored form
f(x) = 3x² - 12
we can take 3 common above
f(x) = 3 ( x² - 4 )
f(x) = 3( x² - 2²)
using formula (a²-b²) = (a+b)(a-b)
f(x) = 3(x+2)(x-2)
