José is on a gameshow that involves a taste test. He gets to see a list of 15 different secret ingredients before tasting 3 dishes one after the other. The 3 dishes are all identical to each other except that each dish contains 1
of the 15 secret ingredients. He gets 60 seconds to identify what secret ingredient was in each dish.

The permutation formula nPr can be used to find the number of unique ways to arrange the ingredients in the
dishes.

What are the appropriate values of n and r?

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

answer: my brother can figure it out, imma go get him so i can answer : ) edit: my brother is sleeping, sorry man

step-by-step explanation:

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
