Answer:
a. Center: (-15, 9), Radius: 5
Step-by-step explanation:
Equation of a circle:
The equation of a circle of center 
and radius r is given by:
In this question, we have that:
Comparing both equations:
And
The center is 
.
For the radius:
The correct answer is given by option a.
The equation in y = mx+b form is y = -450x+2745
where,
x = number of hours that have passed by
y = distance to destination in miles
The y intercept is 2745 since this is the initial starting y value, aka the starting distance. Therefore b = 2745.
The slope is -450 or -450/1 since for each hour, the distance goes down by 450. You can think of it as
slope = (change in y)/(change in x)
slope = (change in distance)/(change in time)
slope = (-450 miles)/(1 hour)
slope = -450
Answer:
(6x-5y)(20y-23x)
Step-by-step explanation:
x(6x - 5y) - 4(6x - 5y)^2
= (6x-5y)(x-4(6x-5y))
= (6x-5y)(x-24x+20y)
= (6x-5y)(20y-23x)
B or 12 would be the correct choice!
