Answer:

Step-by-step explanation:

if we observe carefully we can see that the difference in the number of dots from the first picture to the second picture is 5

and the difference in the number of dots from the second picture to the third picture is 7

so there might be a chance that the difference between the 3rd figure and 4th figure may be 9

so my answer is the number of dots in the 3rd picture + 9

15+9= 24

A letter that represents an unknown number is

Ganezh [65]

Hey there! Hello!

I believe what this question (more of a statement) is asking is to identify what a letter that represents an unknown number is called. Most of the time, i refer to it as just a variable, or an unknown variable. It can also be referred to as just an unknown value.

Feel free to ask me any additional questions if you have any! :-)

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

6n + 7 = 55

Step 2: Solve for n

Subtract 7 on both sides: 6n = 48
Divide 6 on both sides: n = 8

Step 3: Check

Plug in n into the original equation to verify it's a solution.

Substitute in n: 6(8) + 7 = 55
Multiply: 48 + 7 = 55
Add: 55 = 55

Here we see that 55 does indeed equal 55.

∴ n = 8 is a solution of the equation.

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
