Your answer is quite simple, really. All you have to do is divide $3.36 by 7 (The ounces of grapes he bought), and your answer should come out to be $.48, to check if this is correct, you then should add .48, 7 times, or multiply it by 7. Which, is what I did. And that should bring you to 3.36!
The answer is really 3/1 but in it's simplified form it would be 3.
-1 would be the y-intercept<span />
Answer:
A
Step-by-step explanation:
If y = 0.5 x 3^x I will use any 2 points from the table to replace x and y.
Let's use (2 , 4.5) and (3 , 13.5).
0.5 x 3^2 = 0.5 x 9 = 4.5
x = 2 y = 4.5
0.5 x 3^3 = 0.5 x 27 = 13.5
x = 3 y = 13.5
Im pretty sure its -4 soz if im wrong
best of luck (:
