Answer:

The answer to your question is

Step-by-step explanation:

Data

4x - 8y = -16 ------------ (I)

x - 2y = - 8 ------------ (II)

a) Solve equation II for x

x = 2y - 8

Substitute x in equation I

4(2y - 8) - 8y = -16

8y - 32 - 8y = -16

8y - 8y = 32 - 16

0 = 16 The system has no solution because y was

cancelled.

b) When a system of equations do not have solution means that the lines are parallels and different.

Answer:

True

Step-by-step explanation:

$A\cup B=A\cup(A-B)\\\\A\ and\ A-B\ are\ disjoint\ that\ means\ there\ is\ no\ common\ element\ in\ these\ two.\\\\n(A\cup B)=n(B\cup(A-B))\\\\n(A\cup B)=n(B)+n(A-B)\ \ \ \ \ \ \ as\ for\ disjoint\ set\ P,Q\ n(P\cup Q)=n(P)+n(Q)\\\\(n(P-Q)=n(P)-n(P\cap Q))\\\\n(AUB)=n(B)+n(A-B)\\\\n(AUB)=n(B)+n(A)-n(A\cap B)\\\\n(AUB)=n(A)+n(B)-n(A\cap B)\\\\Hence\ given\ statement\ is\ true$
