Question

NEED HELP WILL GIVE MEDAL AND FAN!! Kelly tells you that when variables are in the denominator, the equation one over two plus three over x equals three over four becomes unsolvable. Kelly explains, "There is a value for x that makes the denominator zero, and you can't divide by zero." Demonstrate to Kelly how the equation is still solvable and explain your reasoning.

Answer 1

The equation is still possible because any number multiplied by 0 is zero and the same with division so you don't have to divide you can just multiply. I hope that's correct.

Answer 2

Okay thanks! Will you help me with one more question?

Answer 3

Yes

Answer 4

When looking at a rational function f of x equals the quantity x plus three times the quantity x minus two times the quantity x plus five all divided by the quantity x minus three times the quantity x plus two times the quantity x minus 5, Charles and Bobby have two different thoughts. Charles says that the function is defined at x = −2, x = 3, and x = 5. Bobby says that the function is undefined at those x values. Who is correct? Justify your reasoning.

Answer 5

Thats long hold on a second.

Answer 6

Bobby because anything divided by 0 is undefined.
