Question

IBelow are several statements about the properties of rational expressions.  Indicate whether they are true or false.

1.because you can "cancel the x''s                       5x/x=5

2. because you can "cancel the x's                       5+x/x=5   

                                          
3. because the - 2 and the +2 cancel                     x^2+3x-2/5x+2= x^2+3x/5x

 4.multiply across, and the x's cancel                      8x/5 * 3/x = 24/5

 5. go straight across, and the x's cancel                  1/x+x/4=1/4

 6.because you can add straight across                     4x/7+3/x=4x+3/7+x

7. becasue you only add the numerators                   4x/x+1 + 3/x = 4x+3/x+1

 8.when graphed, both have the same asymptotes    1/x+3 +2 = 2x +7/x+3

Explanation / Answer

1. 5x/x = 5 A 2. 5 + x/x = 5 B 3. x^2 +3x-2/5x+2 = x^2 + 3x/5x C 4. 8x/5 * 3/x = 24/5 D 5. 4x/7 + 3/x= 4x+3/7+x F 6. 1/x + x/4= 1/4 E 7. 4x/x+1 + 3/x+1= 4x+3/x+1 G 8. 1/x+3 +2 = 2x+7/x+3 H
