The amount of time it would take you to go from Chicago to Las Vegas is equal to 1525 miles divided by your average rate of travel. Which equation describes how the time and rate of travel are related?
A. y= 1525/x
x represents rate, y represents time
B. y = 1525x , x represents rate, y represents time
C. y = x/1525; x
represents time, y represents rate
D. y/x = 1525; x represents time, y represents rate

answer: a. 74

step-by-step explanation:

it shows divided evenly, so add the 37+37 = 74

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
