C) 4(9q-r+3)
because you distribute the 4 to the inside of the parentheses. So, 4 x 9q = 36q, 4 x -r = -4r, 4 x 3 = 12. 36q-4r+12 is your answer when you distribute.
a) f (2) = 1
b) 
c) 
<u>Step-by-step explanation:</u>
- Indicates that we have to find the inverse of the function
Given data:
--------> eq.1
---------> eq.2
To find 
Case a)
Now, substitute x = 2 in the equation 1 to find f (2)
Case b)
Now, substitute x = 1 in the equation 2 to find 
Case c)
In general,
Thereby,
Answer:
A: 171.75
B: 170
Step-by-step explanation:
The mean (or average) can be found by...
- add all the numbers together (we will call this y)
- divide the total sum (or y) by the total amount of numbers used to add
Formula:
(x₁ + x₂ + x₃ + ... + xₙ) ÷ n
For A:
(172 + 130 + 173 + 212) ÷ 4 = 171.75
For B:
(136 + 184 + 168 + 192) ÷ 4 = 170
Answer:
f(-1) = 6
Step-by-step explanation:
f(x) = x + 7 when x = -1
~Substitute
= (-1) + 7
~Simplify
= 6
Best of Luck!
