f(x) = -3x + 6
y = -3x + 6
x = -3y + 6
x - 6 = -3y
-3 -3
⁻¹/₃x + 2 = y
⁻¹/₃x + 2 = f⁻¹(x)
g(x) = x + 2
y = x + 2
x = y + 2
x - 2 = y
x - 2 = g⁻¹(x)
Answer:
Part A) 
B) length of BC = x + 12 = x + 12 = 11 + 12 =23
length of EF = 4x - 18 = 4(11) - 18 = 44 - 18 =26
length of AD = 3x - 18 = 3(11) - 4 = 33 - 4 =29
Step-by-step explanation:
Median of trapezium is 
In provided figure, base1 is x+12 and base2 is 3x-4
A) solve for value of x
calculate the median 







B) To find the length of BC, AD and EF , put the value of x in equation of lines
length of BC = x + 12 = x + 12 = 11 + 12 =23
length of EF = 4x - 18 = 4(11) - 18 = 44 - 18 =26
length of AD = 3x - 4 = 3(11) - 4 = 33 - 4 =29
Answer:
The current deer population is 240.
Step-by-step explanation:
The expression given models a exponential decay follows:

For every year that passes since the beginning of the count the population is 0.978 of the year prior. Assuming that the count starts at this year, then "n" is equal to 0, applying this value of n to the formula gives us:

The current deer population is 240.
D. f(x)=4 (5/2)^x

Answer:
25.61 ?
Step-by-step explanation:
use Pythagoreans theorem
a^2+b^2=c^2
20^2+16^2=656
sqrt 656=25.61
