The difference btwn increasing a number by 20% and decreasing the same number by15% is 14 what is the number?

The number is:

Step-by-step explanation:

Let 'n' be the number

As the difference between increasing a number by 20% and decreasing the same number by15% is 14.

Thus, the expression becomes

Multiply both sides by 20

Divide both sides by 7

Thus the number is:

the answer

b. they are parallel and will never intersect.

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
