varies directly means 
inserting y = -18 and x = 3 ⇒
⇒ -6 = k
next, insert k = -6 into the varies directly equation and solve for y. y = -6x
Answer: C
Answer:
5y = x
Step-by-step explanation:
15 miles = 3 hours
Divide by 3 on both sides to find how many miles he/she can run in 1 hour.
15 miles = 3 hours ⇒ 5 miles = 1 hour
Therefore, the equation is just 5y = x.

2 1/3
You would do 6 3/4- 1 3/4=5
5-1 1/3= 2 2/3
Answer:
f(2) = 36
Step-by-step explanation:
given f(x) = 
To evaluate f(2) substitute x = 2 into f(x)
f(2) = 6² = 6 × 6 = 36
