Let x, y ⊂ z and x, y ∈ z let a = (x\{x}) ∪ {x}. a) prove or disprove: a ⊆ x b) prove or disprove: x ⊆ a 4 c) prove or disprove: p(x ∪ y ) ⊆ p(x) ∪ p(y ) ∪ p(x ∩ y ) d) prove or disprove: p(x) ∪ p(y ) ∪ p(x ∩ y ) ⊆ p(x ∪ y )

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right

answer:

a=9

step-by-step explanation: lmk if you need a explanation

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1
