Answer: A∩B is an empty set.

A∩B=\phi

OR

A∩B= { }


Step-by-step explanation:

Given : A = {the sum of the number cubes is odd}

and  B = {the sum of the number cubes is divisible by 2}

We know that odd numbers is not divisible by 2 .

Therefore, the both set have no element common.

Thus, their intersection will be an empty set.

A∩B is an empty set.

A∩B=\phi

OR

A∩B= { }

Answer:

8 hours 20 minutes

Step-by-step explanation:

Given that :

Time Rachel left for school = 7:45 a.m

Time she returned Home = 4:05 p.m

Time for which Rachael was gone :

4:05 p.m - 7:45 a.m

= 8 hours 20 minutes

Rachael was gone for 8 hours 20 minutes

The solution to a system of two linear equations is (4, -3). One equation has a slope of 4. The slope of the other line is the n
astraxan [27]

Answer:

Hello,

First equation is false

Second equation is true

Step-by-step explanation:

1)

(4,-3) is a point of the line y=4x-19  since

-3=?4*4-19

-3=-3

2)

(4,-3) is not a point of the line y=1/4x-2 since

-3=? 1/4*4-2

-3=? 1-2

-3≠-1

I have written that because it is difficult for me to understand

"the negative reciprocal of the slope of the first"

the negative reciprocal of 4 should be -1/4.

Equation y=1/4x-2 is false.
