x^2-xy+3y^2=15           x-y=2

Make the equation X:

x = y + 2

Plug in and Solve:

(y+2)^2 - y(y+2) + 3(y+2)^2 = 15

y = (√46) - 7/3

y = - 7 + (√46)/3

Mr. Sánchez owns a square field. The side lengths are 0.9 kilometers. There are 1,980 prairie dog burrows in the fields. What is
Simora [160]
The first thing we are going to do is find the area of the field. To do this we are going to use the area of a square formula: A=s^2
Were 
A is the area in square kilometers 
s is one of the sides of the square
We know for our problem that  the side lengths of the field are 0.9 kilometers, so s=0.9. Lets replace that value in our formula to find A:
A=(0.9)^2
A=0.81 

Now, to find the population density of the filed, we are going to use the population density formula: P_{d}= \frac{I}{A}
where
P_{d} is the population density in <span>in burrows per square kilometer
</span>I is the number of burrows 
A is the are of the field
We know that I=1980 and A=0.81, so lets replace those values in our formula:
P_{d}= \frac{1980}{0.81}
P_{d}=2444.4

We can conclude that the <span>density of prairie dog burrows is approximately 2444 burrws per square kilometer.</span>

Abe, Bob, Carl, Dan and Earl are going to stand in line for a photo. What is the probability that the boys will stand in alphabe
Levart [38]

Answer:

0.0083 = 0.83% probability that the boys will stand in alphabetical order from left to right in the picture

Step-by-step explanation:

Probability:

A probability is given by the number of desired outcomes divided by the number of total outcomes.

Arrangments of x elements:

The total number of arrangments of x elements is given by:

A_{x} = x!

Desired outcomes:

Standing in alphabetical order, so only 1 possible outcome, which means that D = 1

Total outcomes:

Arrangments of 5 people, so

T = A_{5} = 5! = 120

Probability:

p = \frac{D}{T} = \frac{1}{120} = 0.0083

0.0083 = 0.83% probability that the boys will stand in alphabetical order from left to right in the picture
