1) find the function AND solution of (y = 5x - 4 when x = 5) (y = - 2/5 x + 3/8 when x = 1/3) (y = 3x + 12 when x = 4)
-
2) Show set of data that is a function using at least 5 domain values and 5 range values. It can be shown
in a format of your choice (graph, table, set notation).

Answers

Answer:

Step-by-step explanation:

1)

y = 5x-4 when x=5

y = 5*5-4

y = 25-4

y = 21

y = -2/5x + 3/8 when x = 1/3

y = -2/5 * 1/3 + 3/8

y = -2/15 + 3/8

y = -6/120

y = -1/20

y = 3x + 12 when x = 4

y = 3*4 + 12

y = 12 + 12

y = 24

Pam drove her car 99 kilometers and used 9 liters of fuel. She wants to know how many kilometers (k) can she drive with 12 liters of fuel. How many kilometers can Pam drive with 12 liters of fuel ?

Answers

Assume Pam used the same volume of fuel in every kilometres (In reality, it might not be). 12 divided by 9 is 4 over 3, this means that 12 is 4/3 times bigger than 9. 99 times 4/3 is 132.

Answer:

132 liters

Step-by-step explanation:

First divide 99 by 9 to see how much fuel she needs per kilometer

99/9=11 now multiply 11 by 12 to get  the amount of fuel she needs to drive 12 meters

12*11= 132 she needs 132 liters of fuel
