Answer:
false
Step-by-step explanation:
12 - x ≠ 5
--
because

if x = 8 then 12 - 8 = 5; which is false
The possible functions for f and g are f(x) = and g(x) =
<h3>What is an exponential function?</h3>
An exponential function is a mathematical function of the following form: f ( x ) = where x is a variable, and p is a constant called the base of the function. The most commonly encountered exponential function base is the transcendental number e.
Analysis:
If for every value of x being positive and y is a positive whole number and for every x being negative y is a positive fraction, then that exponential function has a whole number base, Other wise it would have a fractional base. From the above explanation, f has (1,3) (positive x and whole number y) and (-1, 1/3) (negative x and positive fraction y). so therefore f has a whole number base and g has a fraction base.
Therefore f(x) = and g(x) =

Answer:
The value of x is 2/3.
Step-by-step explanation:
The perimeter of a square is 4s.
Substitute the value and simplify.
4( 3x - 2 ) Distribute
12x - 8 In this case this is an equation
12x - 8 = 0 Add 8 on both sides
12x = 8 Isolate the variable by dividing 12 on both sides
x= 2/3
You must isolate the variable in order to solve equations with variables.
Isolating variable is basically when you divide, multiply, add, or subtract to put a variable on <em><u>ONLY </u></em>one side of the equation.

Answer:
11n=35
Step-by-step explanation:
First, you do 2n+9n
2n+9n+11n
11n-8=27
Next, you add 8 to each side
11n=27+8
11n=35
