1. (1-2)/(3-5) = (-1)/(-2) = 1/2
2. (0-4)/(-5-7) = (-4)/(-12) = 1/3
To find the slope you’d do the second y-value minus the first y-value over the second x-value minus the first x-value.
Answer:
Infinite number of solutions
Step-by-step explanation:
The two expressions are actually equal to each other. When two functions are equal to each other, they will have infinite number of solutions.
The width of the rug is 9 feet.
Step-by-step explanation:
Perimeter of rug = 42 feet
Lengths are same in square and rectangle shapes; therefore;
Length of rug = 12 feet
Width of rug = w
Perimeter = Length + Length + Width + Width
Perimeter = 
Dividing both sides by 2
The width of the rug is 9 feet.

Answer:
420 miles.
Step-by-step explanation:
You would have to be infinitely far away from a sphere in order to see exactly 50% of its surface all at the same moment. Using simple geometry, you can prove that an observer that is a distance d away from the surface of a sphere with radius R can only see a percent area A of the sphere's surface as given by the equation:
A = 50%/(1+R/d)
Where A is the area seen,
R is the earth's radius 4000 miles
And D is the distance above the earth 200 miles
50% = 0.5 in fraction
Substituting values we have
A = 0.5(1 + 4000/200)
A = 0.5(1 + 20) = 0.5 x 21
A = 10.5%
10.5% of 4000 miles = 420 miles.
