Answer:
7 miles / hour
Step-by-step explanation:
I'm taking this to mean she walked 3.5 miles. She did this 1/2 hour.
Givens
d (distance ) = 3.5 miles
t (time) = 1/2 hour
r (rate) = ?
Formula
r = d/t
Solution
The easiest way to do this is to change the fractions to decimals.
t = 1/2 = 0.5 hours
r = 3.5 / 0.5
r = 7 miles per hour.
(a) False. The number 7 is NOT an element of set B as 7 is not in the set B (2, 3, 4 and 0 are though)
(b) False. 3 is a member of set A. It is the third element listed in the set. So saying "3 is not a member of set A" is a false claim
(c) True. The value 0 is found in set B. It is the last element listed.
Final Answer: Choice C)

I didnt feel like typing it out but the explanation is in the picture hope this helps :)
Answer:
(1,4),(2,12)
----------
The form is y = ab^x
12 = ab^2
4 = ab^1
------------
Divide the 1st by the 2nd to get:
3 = b
--------
Substitute that into the 2nd equation to solve for "a":
4 = a*3^1
a=(4/3)
-------------
EQUATION:
y = (4/3)*2^x
