How many subsets does set a have if set a has 3 elements

Good morning ☕️

Step-by-step explanation:

it has 8 subsets.

>Remember< : the number of subsets that set A have if set A has n elements

equal to 2ⁿ

In this case we A have 3 elements then its number of subsets is 2³=8

:)

Hey!!!

Here's your answer

-4(y-2)=12

or,-4y+8=12

or,-4y=12-8

or,-4y=4

or,y=4/-4

y=-1

So the value of y is -1

Hope it helps...

Good luck on your assignment
