What is the solution for x in the equation -3x+7x-8=34+9x-2

x= -8

Step-by-step explanation:

1) -3x+7x-8=34+9x-2

2) -3+7x-9x=8+34-2

3) -5x=40

4) x= 40/-5= -8

In the first step you have to separate the x from the numbers,placing on the left the terms that contain it and on the right the rest. When you do this step you need to change the signs of shifted numbers (-8 has become +8),then you can perform an algebraic sum (for istance: -3+(-9)=-12; -12+7=-5). Your last step will be the division between the term with and without x that are respectively denominator and numerator. After that, you'll conclude.

I hope I have helped,byee ;)

the answer is d

step-by-step explanation:

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
