Step-by-step explanation: In order for a function not to be a relation,

each x-coordinate must correspond to more than one y-coordinate.

Notice that in third relation, the 1 pairs with a 3

in one case and it pairs with a 7 in the other case.

Since each x-coordinate pairs with more than one y-coordinate,

this relation is not a function but the other ones are functions.

Determine whether the two questions are equivalent. If so, name the property that is applied. 54 - (30 - 8) and (54-30) - 8

Sphinxa [80]

Answer:

The two equations are not equivalent and no property is used.

Step-by-step explanation:

54 - (30 - 8) ... (i)

(54 - 30) - 8 ... (ii)

Solving (i) and applying PEMDAS:

We open the brackets first;

54 - 30 + 8 = 54 + 8 - 30 = 32

Solving (ii) and applying PEMDAS:

We open the brackets first;

54 - 30 = 24

24 - 8 = 16
