Answer:

x = -21/5

Step-by-step explanation:

Notice that each new y- value is 3 times the previous y-value.  Thus, the function is y = 3^(n-1).

Check:  If n = 1, y = 3^0 = 1.  This is correct.

             if n = 3, y = 3^2 = 9.  This is correct.

If 14 people show up to a cookout and you make 21 hot dogs, how many will you need to make if 105 people up?
Oksanka [162]

Answer:

Step-by-step explanation:

let x = number of  of hot dogs that 105 people  will do

therefore

14 people = 21 hot dogs

105 people = x hot dogs

14 x 105 people = 21 x Xhotdogs

1470 = 21X

divide through by 21

1470/21 = 21X/21

70 = X

X = 70

therefore,

105 people will makev 70 hot dogs
