8 0

Answer:

Step-by-step explanation:

1 quart = 32 fluid ounces

4 quart = 32 x 4 = 128 ounces

Rate of 128 ounces = 128 ÷ 5.12 = 25

Rate of 79 ounces = 79 ÷ 3.95 = 20

4 quart jug is a better buy

If AA and BB are countable sets, then so is A∪BA∪B.
Lostsunrise [7]

Answer with Step-by-step explanation:

We are given that A and B are two countable sets

We have to show that if A and B are countable then A\cup B is countable.

Countable means finite set or countably infinite.

Case 1: If A and B are two finite sets

Suppose A={1} and B={2}

A\cup B={1,2}=Finite=Countable

Hence, A\cup B is countable.

Case 2: If A finite and B is countably infinite

Suppose, A={1,2,3}

B=N={1,2,3,...}

Then, A\cup B={1,2,3,....}=N

Hence,A\cup B is countable.

Case 3:If A is countably infinite and B is finite set.

Suppose , A=Z={..,-2,-1,0,1,2,....}

B={-2,-3}

A\cup B=Z=Countable

Hence, A\cup B countable.

Case 4:If A and B are both countably infinite sets.

Suppose A=N and B=Z

Then,A\cup B=N\cup Z=Z

Hence,A\cup B is countable.

Therefore, if A and B are countable sets, then A\cup B is also countable.

Equation of the line (-6,5) and (8,14) in standard form
blsea [12.9K]

Answer:

\huge\boxed{9x-14y=-70}

Step-by-step explanation:

The point-slope form of an equation of a line:

y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

We have two points (-6, 5) and (8, 14).

Substitute:

m=\dfrac{14-5}{8-(-6)}=\dfrac{9}{14}\\\\y-5=\dfrac{9}{14}(x-(-6))\\\\y-5=\dfrac{9}{14}(x+6)

Thew standard form of an equation of a line:

Ax+By=C

transform:

y-5=\dfrac{9}{14}(x+6)\qquad|\text{multiply both sides by 14}\\\\14y-14\cdot5=14\!\!\!\!\!\diagup^1\cdot\dfrac{9}{14\!\!\!\!\!\diagup_1}(x+6)\\\\14y-70=9(x+6)\\\\14y-70=9x+54\qquad|\text{subtract}\ 9x\ \text{from both sides}\\\\-9x+14y-70=54\qquad|\text{add 70 to both sides}\\\\-9x+14y=70\qquad|\text{change the signs}\\\\9x-14y=-70
