How do I find the point of intersection?

Answers

Answer:

(-1 3/5, 2 3/5)

Step-by-step explanation:

Red Line:

m = 3-(-1)/-2-2 = 4/-4 = -1

b = 1

equation:  y = -x + 1

Blue Line:

m = 5-1/2-(-4) = 4/6 = 2/3

find 'b':

5 = 2(2/3) + b

15/3 = 4/3 + b

b = 11/3

equation:  y = 2/3x + 11/3

Find Point of Intersection:

-x + 1 = 2/3x + 11/3

multiply each side by 3 to get:

-3x + 3 = 2x + 11

-5x = 8

x = -8/5

find 'y':

y = -(-8/5) + 1

y = 8/5 + 1 = 13/5

y = 2 3/5

Largest:

Answers

Answer:

Smallest: 15,840 ft

Largest: 16,896 ft

Step-by-step explanation:

1 mi = 5,280 ft

Setup proportion to solve for the smallest:

[tex]\frac{1mi}{5,280ft} =\frac{3mi}{xft}[/tex]

Do butterfly method and you should get this:

[tex]xft=3(5280)\\x=15,840ft[/tex]

The revenue, R, promised to the contractor is $1,00,000.Required:a. The contract will be profitable if revenue exceeds total cost. What is the probability that the co ntract will be profitable for the contractor?b. What is the probability that the project will result in a loss for the contractor?c. Suppose the contractor has the opportunity to renegotiate the contract. What value of R should the contractor strive for in order to have a .99 probability of making a profit?
