Are the expressions equivalent? Usej = 3 and j = 8 to determine if they are.76-2)4- 5O No, because when j = 8, the values of the expressions are different.Yes, because when j = 3, the value of both expressions is 7 and when j = 8. the value of both expressions is 42.Yes, because when j = 3, the value of both expressions is 7Yes, because when j = 8, the values of the expressions are different.

Respuesta :

We have the followong two expressions:

7 (j - 2) and 4j - 5

Let's use j=3 to determine if they are equivalent:

7 (3 -2) = 4 * 3 - 5

7 * 1 = 12 - 5

7 = 7

They are equivalent

Now, let's use j = 8 to do the same:

7 (8 - 2) = 4 * 8 - 5

7 * 6 = 32 - 5

42 is not equivalent to 27
