A 3-mi cab ride costs $7.30. A 8-mi cab ride costs $15.30. Find a linear equation that models a relationship between cost c and

distance d.
Select one:
a. c = 1.91d + 2.50
b. d = 1.60c + 8.00
c. c = 1.60d + 2.50
d. c = 2.43d + 8.00

Since, A 3-mi cab ride costs $7.30 and a 8-mi cab ride costs $15.30.

In the information given above, we can consider these as the coordinate points on the axes.

Let (c, d) be the coordinates , where 'c' represents the total cost and 'd' represents the distance traveled.

Cost is on the 'y' axis and distance is on the 'x' axis.

Now, let the first point on the coordinate axes be (3, 7.30) and the other point is given by (8, 15.30).

For the given points say (x_1,y_1) and (x_2,y_2) , equation of line is given by:

(y-y_1)= m(x-x_1) where m(slope) is given by \frac{y_2-y_1}{x_2-x_1}.

The equation of line for the given points is:

(c-7.30) = (\frac{15.30-7.30}{8-3})(d-3)

(c-7.30) = 1.6(d-3)

c-7.30 = 1.6d-4.8

c-1.6d=2.5

So, c = 1.6d+2.5 is the required linear equation that models a relationship between cost c and distance d.

Naddika [18.5K]

Answer:

They started at 4:45 pm

Step-by-step explanation:

Time spend at the mall:

15 minutes in the shoe store

1 hour shopping for a dress

30 minutes eating

Total 1 hour 45 minutes

x + 1 hour 45 minutes = 6:30

Subtract 1 hours

5 : 30 pm

Subtract 45 minutes

4 :45 pm

They started at 4:45 pm

Artist 52 [7]
There are a total of 31 fish in the tank. Therefore, the probability of it being a goldfish is 24/31 or about 77.4%, since there are 24 goldfish. The probability of it being an angel fish is 2/31 or about 6.45%, for the same reason as before.
