4 (2x-6)=10x-6. solve for x
Reika [66]

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : 

   4*(2*x-6)-(10*x-6)=0 


   2x - 6  =   2 • (x - 3) 

   8 • (x - 3) - (10x - 6) = 0 

   -2x - 18  =   -2 • (x + 9) 

 -2 • (x + 9) = 0 

Solve :    -2   =  0

<span>This equation has no solution.
</span>A a non-zero constant never equals zero.

Solving a Single Variable Equation : 
 Solve  :    x+9 = 0 

<span>
 </span>Subtract  9  from both sides of the equation :<span> 
 </span>                     x = -9

What is the inverse of function f? f(x)=10/9+11
Lena [83]

Answer:

Option D is answer.

Step-by-step explanation:

Hey there!

Given;

f(x) = 10/9 X + 11

Let f(X) be "y".

y = (10/9) X + 11

Interchange "X" and "y".

x = (10/9) y + 11

or, 9x = 10y + 99

or, y = (9x-99)/10

Therefore, f'(X) = (9x-99)/10.

The option that represents the answers for 6, 8, 10, and 14 is the second option-   31, 41, 51, 71

<h3>Sequence and Series </h3>

From the question, we are to determine the option that represents the answer for pictures 6, 8, 10, and 14

In the given diagram,

The first picture requires 6 matches

The 2nd picture requires additional 5 matches

the 3rd  picture requires additional 5 matches

and so on

That is

1 → 6

2 → 6 + 5 = 11

3 → 11 + 5 = 16

4 → 16 + 5 = 21

5 → 21 + 5 = 26

6 → 26 + 5 = 31

7 → 31 + 5 = 36

8 → 36 + 5 = 41

9 → 41 + 5 = 46

10 → 46 + 5 = 51

11 → 51 + 5 = 56

12 → 56 + 5 = 61

13 → 61 + 5 = 66

14 → 66 + 5 = 71

Hence, the option that represents the answers for 6, 8, 10, and 14 is the second option-   31, 41, 51, 71
