Anyone know the answer to this one ?

Answer: B) y = 2 · 3ˣ

Step-by-step explanation:

We can see that (2, 18) is a point on the graph.

Plug it into the equations to see which one make a true statement.

A) y = 1 · 3ˣ

18 = 1 · 3²

18 = 1 · 9

18 ≠ 9

B) y = 2 · 3ˣ

18 = 2 · 3²

18 = 2 · 9

18 = 18 This works!

C) y = 3 · 2ˣ

18 = 3 · 2²

18 = 3 · 4

18 ≠ 12

D) y = 4 · 3ˣ

18 = 4 · 3²

18 = 4 · 9

18 ≠ 36

How do I solve this problem (I did the graph)

Andrej [43]

C = - 1/2t + 6
The equation usually looks like this

C = k*t + n

If t = 0 than

C = n (from the table we see that C is 6 if t = 0) than

N = 6 too

For t = 2 and c = 5 we have the equation

5 = 2k + 6
2k = -1
K = -1/2

A proportional relationship betweeof potatoes (x) and the price in dollars (y) is graphed, and the ordered pair (4, 3) is on the

CaHeK987 [17]

4/3 = 1/x.....4 lbs potatoes to $3 = 1 lb of potatoes to $x
cross multiply
(4)(x) = (3)(1)
4x = 3
x = 3/4
x = 0.75....so 1 lb of potatoes cost 75 cents

(8,6)...this means 8 lbs of potatoes cost $6
