A. 2(x+14) = 42
(2x = 14
x = 7
2(7) + 2(14) = 14 + 28 = 42)
The
formula
, where r! is 1*2*3*...r
is the
formula which gives us the total number of ways of forming groups of r objects out of n objects.
for
example, given 10 objects, there are C(10,6) ways of forming groups of 6, out
of the 10 objects.
<span>Thus, there are C(6, 3) many ways of forming different triples out of 6.</span>

Answer: A.20
Answer:
approx. 13 games
Step-by-step explanation:
8 x
-- = --
40 64
cross multiply-
8*64=512
512/40=12.8
round up to 13
Answer : domain: {x | x is a real number}; range: {y | y >- 8}
the domain and range of 
For exponential function , there is no restriction for x
So domain is all real numbers
For exponential function , 
The range is y > b
The range of
is y> -8
domain: {x | x is a real number}; range: {y | y > –8}
