Question 4948: Write a formula that expresses the relationship described below. Match your result to the correct answer below.
r varies as t and r = –4 when t = 2. Answer by rapaljer(4671) (Show Source):
You can put this solution on YOUR website! First write the equation, where r and t are variables and k is a constant to be determined:
r=kt
Plug in the values of r= -4 and t= 2:
r= kt
-4 = k* 2
Divide both sides by 2, and get
-2 = k
Now substitute that value of k=-2 into the original equation:
r=kt
