Answer:

Infinitely many.

Step-by-step explanation:

Combine like terms as shown below

x + 12 + 2x = 20 + 3x - 8

Side one

x + 2x = 3x

Side two

20 - 8 = 12

Set the equation up again

3x + 12 = 3x + 12

The equation is the same on both sides which means that the equation cancels itself out.

3x - 3x = 0 and 12 - 12 = 0

0 = 0 so there is infinitely many solutions because both sides equal the same thing.

What ate the domain and range of f(x)(1/6)x+2?

never [62]

Answer:

Domain : all real numbers

Range: All numbers greater than 2

Step-by-step explanation:

The shark. (Haha, I'm sorry.)

There are no restrictions on the x. X can be any real number.

The range, however, does have restrictions. The range has to be a number greater than 0.

Why?

Because any number that you put in for x won't make the range less than 2. If you put in zero for x, the range is 2.
