None of them match the answer is really (-2,2), (-4,2), and (-2,8).
Part A: This data does represent a function because no value of x is repeated.
Part B: If x = 6 for the relation f(x) = 7x - 15, then f(x) will equal 27. The function f(x) = 7x - 15 will have the greater value
Part C: If f(x) is equal to 6 then x will equal 3
Answer:
Since Roman walks 1 more than Patrick then you have to subtract 1 from Patricks number of miles.
Multiply the numbers: 3 x 2=6 = 6x + 5 - 12x - 2 x 149x
Next Multiply the numbers 149 x 2 = 298
Then, Group like terms, =-6x-12x-298x+5
Add similar elements -6x-12x-298x=-316x,
and you get -316x+5!
Ur answer will be 168 because it’s the smallest number that all of the numbers divide into evenly
