The Topology Taxi Company charges 2.80 for the first fifth of a mile and 0.45 for each additional fifth of a mile. Find a linear function which models the taxi fare F as a function of the number of miles driven, m .

F=2.2375+2.25m is a linear function which models the taxi fare F as a function of the number of miles driven, m

Step-by-step explanation:

a+0.25=m

a=m-0.25

a/0.20=d

(m-0.25)/0.20=d

F=2.80+0.45(m-0.25)/0 20

=2.80+2.25(m-0.25)

=2.80+2.25m-0.5625

=2.80-0.5625+2.25m

F=2.2375+2.25m

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
