Question

I WILL FAN AND MEDAL PLZ HELP!!

Answer 1

well you can eliminate the middle choices as you would see a negative number of comets sighted

have a look at the 1st and last choice....

is x = 1, the year is 1991 and there should be 75 comets..

which equation gives a number close to 75 when you substitute x = 1

and then check substitute x =2 which will be 1992 is the number of comets close to the number seen...

hope this helps

Answer 2

thankyou:)

Answer 3

wait im completly lost sorry

Answer 4

ok... so you need look at the table for 1991

this means x = 1 and f(1) = 75

so for the 1st choice f(1) = 4.85*1 + 69.85 approx 75

4th choice f(1) = 4.85 * 1 + 21 approx 75

which gives the answer closest to 75..?

Answer 5

1st choice

Answer 6

ok... so check it by selecting the year 1992 so x = 2

subsitute that, is the answer close to the actual number of sightings, 79..?

if so, that would be my choice.
