Which algebraic expression represents the phrase “two times the quantity of a number minus 12”? 2y - 12 2(y -12) 2(y + 12) 2y + 12

Step-by-step explanation:

Let:

Now, we need to express “two times the quantity of a number minus 12” mathematically.

First, let's represent “two times the quantity of a number" which is an arbitrary number or constant multiply by 2:

Now, to this result, we need to subtract 12, therefore:

This is the algebraic expression that represents the phrase given.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
