A car is traveling on a highway. The distance (in miles) from its destination and the time (in hours) is given by the equation d = 420 minus 65 t. What is the slope of the line represented by the equation? What is the practical meaning of the slope? a.
m = 420; The total distance is 420 miles.
b.
m = 65; The car is traveling 65 miles per hour.
c.
m = negative 65; The car is traveling 65 miles per hour.
d.
m = negative 420; The total distance is 355 miles.

step-by-step explanation:

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !

answer: hence, function will be

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be
