Is 3x+4y=7 linear or nonlinear

Sloan [31]

Linear. It's in the form C= ax + by, so you back solve to get into the form you know is linear (y= mx + b). So using SADMEP (opposite of Pemdas) we can decide which order to solve for "Y=" in. 4y =7-3x. Y=((7-3X)/4). Y= 7/4 -3/4x. Y=-3/4x +7/4. Which is linear

In Wellington, a city of 360,000 citizens, there has been an outbreak of vampires and werewolves There are 3,000 people infected

Alex17521 [72]

Answer:

0.0286 or 2.86%

Step-by-step explanation:

The total number of people that have werewolfism is 21,000.

Of those 21,000, 600 also have vampirism, while the remaining 20,400 do not. Therefore, the probability that someone has vampirism, given that they have werewolfism is:

$P(V|W)=\frac{N_{V\cap W}}{N_W}\\P(V|W)=\frac{600}{21,000} \\P(V|W)=0.0286=2.86\%$

The probability is 0.0286 or 2.86%.

What is 25.5n - 3 = 5.5n + 10.

klemol [59]

N = 13/20 or 0.65

25.5n - 3 = 5.5n + 10

Add 3 to both sides of the equation.

25.5n = 5.5n + 13

Subtract 5.5n from both sides.

20n = 13

Divide both sides by 20.

n = 13/20 or 0.65
