Is x+y=10 a direct variation?

Yes, x+y could possibly be a direct variation, but in order to determine that correctly, we need a second equation. 

If y varies directly with x, then it IS a direct variation.

Because we can determine its a direct variation just based upon the x and y.

Flura [38]

Answer:

$20,285.51

Step-by-step explanation:

A = P + I where

P (principal) = $12,000.00

I (interest) = $8,285.51

A = Pe^(r*t)

A = 12,000.00(2.71828)^((0.075)*(7))

A = $20,285.51

e, also known as Euler's number, is a mathematical constant approximately equal to 2.71828

e here helps to show continously compounded interest

Since the beginning of the year, 1982 people have come into a blood bank to donate blood and 340 were found to have high blood p
Alecsey [184]

Answer:

0.1715

Step-by-step explanation:

From previous experience 340/1982 is the past probability that a person has high blood pressure.

The division of that leads to 0.1715 that the next person will have high blood pressure. That number is roughly (very roughly) 1 person in 6. So if 6 people come in 1 will have high blood presure.

If 3x + 5y = 2 and 2x - 4y = 20, what is 5x - y?
gavmur [86]

Answer:

= 298/11

Step-by-step explanation:

3x + 5y = 2 | ×2 |

2x - 4y = 20 | ×3 |

6x + 10y = 4

6x - 12y = 60

____________--

22y = -56

y = -56/22

y = -28/11

3x + 5y = 2 | ×4 |

2x - 4y = 20 | ×5 |

12x + 20y = 8

10x - 20y = 100

_____________+

22x = 108

x = 108/22

x = 54/11

5x - y

= 5(54/11) - (-28/11)

= 270/11 + 28/11

= 298/11
