Answer: Choice A) 1/9
--------------------------------------------
--------------------------------------------
Work Shown:
Replace every x with -4 and then simplify the right side
f(x) = 9(3)^x
f(-4) = 9(3)^(-4)
f(-4) = 9*(1/(3^4)) See note below
f(-4) = 9*(1/(3*3*3*3))
f(-4) = 9*(1/81)
f(-4) = 9/81
f(-4) = 9/(9*9)
f(-4) = 1/9
Note: I used the rule x^(-n) = 1/(x^n) which allows us to convert from negative exponents to positive ones.
Answer:
Tax = $0.75
Tip = $2.25
Total (meal + tax + tip)= $18.00
Step-by-step explanation:
When solving for percentages of a number, such as sale tax and tip, multiplying the decimal equivalent of each percentage to the amount will give you the individual costs. For example, in this case the sales tax is 5%, the decimal equivalent of 5% = 5 ÷ 100 = 0.05. To find the amount of tax on Allam's meal, multiply the rate by the amount:
0.05 x $15 = $0.75
Since he plans to leave a 15% tip, we can also multiply the amount of the meal by the planned tip amount:
15 ÷ 100 = 0.15
0.15 x $15 = $2.25
Total amount paid, including tax and tip:
$15 + $0.75 + $2.25 = $18.00
Answer:
So I (3,0) becomes I' (1,3)
H (5,2) H' (1,1)
G (2,4) G' (2,1)
Step-by-step explanation:
So let's start with I, just count how many times you move to the left then how many times you move up.

Answer:
x² + 4x + 3
Step-by-step explanation:
to find f(g(x)), substitute x = g(x) into f(x)
f(g(x)) = f(x + 2) = (x + 2)² - 1 = x² + 4x + 4 - 1 = x² + 4x + 3
