3x + 9 = 44 - 2x (add 2x to each side)
5x + 9 = 44 (minus 9 from each side)
5x = 35 (divide each side by 5)
x = 7

3 x + 9 = 44 - 2 x

subtract 9 from both sides:

3 x + 9 - 9 = 44 - 2x - 9

3 x = -2 x +35

Add 2 x to both sides:

3 x + 2 x = -2 x + 35 + 2 x

5 x = 35

Divide both sides by 5 :

5x / 5 = 35/ 5

x = 7

hope this helps!

If f(x) = <img src="https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B9%7D" id="TexFormula1" title="\frac{1}{9}" alt="\frac{1}{9}" align=

Answer:

Solution given:

f(x) = $\frac{1}{9}$ x-2

let f(x)=y

y = $\frac{1}{9}$ x-2

interchanging role of x and y

x= $\frac{1}{9}$ y-2

x+2= $\frac{1}{9}$ y

y=9(x+2)

y=9x+18

F-¹(x)=9x+18

and

F-¹(-1)=9*-1+18=-9+18=9

Answer:

Domain={2,5,8}

Range={1,3,6}

Function: YES

Step-by-step explanation:

The Domain of a Function

Is the set of values the input variable x takes.

Range of a Function

It's the set of values the output function takes when x moves into the function's domain.

A function is a relation between an input and an output set of values with the condition that every element in the domain relates only with one element in the range.

Following the definitions above, the domain of the relationship is the set of input values:

Domain={2,5,8}

The range is the set of output values:

Range={1,3,6}

Since each element in the input set is related only to one element in the range, the given relationship is a function.

Answers:

Domain={2,5,8}

Range={1,3,6}

Function: YES
