Question

Is each equation true or are some of them false?

1. y x y x y – y = 2y True or False

2. a divided by b = 1/2(a divided by b) True or false

3. v = v to the power of 3 divided by v to the power of 2 True or false

1 is true 2 is false 3 is true

thaiduong · Answer

1. False. y x y x y = y^3, not 3y, so it would equal y^3 – y.

2. False. Half of the original amount will never equal the original amount.

3. True. When you divide variables with exponents, you subtract the exponents. Therefore, v^3 / v^2 = v^3-2 = v
