Answer:
C. f(x) = 3(2 x)
Step-by-step explanation:
Answer:
f( g(x)) = 18 *x*x + 6
g( f(x)) = 6xx + 18
Step-by-step explanation:
we want f (g(x)) and g( f(x))
f = 2xx + 6 g = 3x
f( g(x)) = 2 *(3x)*(3x) + 6 = 18 *x*x + 6
g( f(x)) = 3*(2 xx + 6 ) = 6xx + 18
Answer:
Mean Absolute Deviation (MAD): 8.5
Step-by-step explanation:
Xmean = (28 + 32 + 47 + 16 + 40 + 35 + 38 + 54)/8 = 290/8
Xmean = 36.25
MAD =
(28 - 36.25) + (32 - 36.25) + (47 - 36.25) + (16 - 36.25) + (40 - 36.25) + (35 - 36.25) + (38 - 36.25) + (54 - 36.25) divided by 8
a break down of each ( )
(8.25) + (4.25) + (10.75) + (20.25) + (3.75) + (1.25) + (1.75) + (17.75) divided by 8 = 68
then you take 68/8 = Mean Absolute Deviation 8.5
Answer: You rewrite in factor form which for this is (3x+2)(3x-2).
Step-by-step explanation:
Answer:
9m-45
Step-by-step explanation:
