A. Let x represent the number of miles and y represent the total price.
y=3x+15
B. Using the equation we just wrote, replace the x with 45.
y=3(45)+15
Now multiply 45 by 3.
y=135+15
And finally add together 135 and 15.
y=150
The total cost of a 45 mile taxi ride would be $150.00.
The general equation of a hyperbola with a horizontal transverse axis is defined as:
x²/a² - y²/b² = 1
Solving for b², we use the formula: a² + b² = c²
b² = 12² - 9² = 63
Equation of our hyperbola will be:
x²/81 - y²/63 = 1

Answer: 3
Step-by-step explanation:
Answer:
The new area is 1800feet^2
Step-by-step explanation:
Step one:
Given data
The length and width or a rectangular courtyard is 40 feet and 30 feet
we can calculate the area of the courtyard as
Area= 40*30
Area= 1200 feet^2
when the extra 15 feet is added to the width
the new width is= 30+15= 45feet
The new area is
Area= 40*45
Area= 1800 feet^2
in all the area will increase by 1800-1200= 600feet
