Answer:
f(g(x)) = 10x + 7
Step-by-step explanation:
(f . g)(x) = f(g(x)) is the composition of the functions f(x) and g(x).
f(g(x)) means that g(x) becomes the input for f.
Now, f(x) = 2x - 3 and g(x) = 5x + 5.
f(g(x)) = f(5x + 5)
= 2((5x + 5) - 3)
= 10x + 10 - 3
= 10x + 7
f(g(x)) = 10x + 7 is the required answer.
The answer is x= -3, or <span> x = -2/11 = -0.182</span>
Answer:
all real numbers greater than zero
Step-by-step explanation:
The square root of a number must be greater than or equal to zero
sqrt(x) ≥0
Squaring each side
x ≥0
This means the domain is all real numbers greater than or equal to zero
I would go with all real numbers greater than zero since it is the closest answer
Answer:
x + y <u>></u> 15
10x + 5y <u><</u> 100
we will put it in terms of y
y <u>></u> 15 - x
and
5y <u><</u> 100 - 10x
y <u><</u> 20 - 2x

$15,000 * 0.8 = $12,000
$12,000 * 0.8 = $9,600
$9,600 * .08 = $7,680
