Tell whether the relation is a function. {(-5, -3), (-1, 3), (4, 3), (8, 8)}

VladimirAG [237]

Given:

The relation is {(-5, -3), (-1, 3), (4,3), (8, 8)}.

To find:

Whether the given relation is a function or not.

Solution:

A relation is called a function, if there exist a unique output for each input.

We have, a relation given as

{(-5, -3), (-1, 3), (4,3), (8, 8)}

Here, all x-values are different. So, each x-value has a unique y-value.

Thus, there exist a unique output for each input.

Therefore, the given relation is a function.

Mary can clean her apartment in 6 hours, while her roommate can clean the apartment in 5 hours. if they work together, how long

defon

Answer:

2 hours and 44 minutes.

Step-by-step explanation:

In 1 hour, Mary can clean 1/6 of the apartment, while her roommate cleans 1/5 of the apartment. To represent both of them working together, you add both fractions : 1/5 + 1/6 = 11/30. To find out how long it would take, you divide 1 by 11/30. 1/1 ÷ 11/30 = 1/1 × 30/11 = 30/11 hours. Make the fraction a mixed number : 30/11 = 2 8/11. 8/11 ≈ 0.727. Multiply 0.727 with 60 minutes : 0.727 × 60 = 43.62 minutes. Round 43.62 : 44 minutes. Result : 2 hours and 44 minutes.

X + 4y = 23<br> -3x = 12y + 1<br> is it no solution?

bagirrra123 [75]

Answer: Yes

Step-by-step explanation:

First multiply the first equation by three to get 3x+12y=69

Then subtract 12y from both sides of the second equation

Then add the first system and the second like this:

$3x+12y=69\\-3x-12y=1\\--------\\0+0=70\\0=70$

Because 0≠70, the system has no solutions
