Inverse variation means y=k/x (direct variation is y=kx)
You are given a point, so you can solve for the constant k...
2=k/15
k=30 so the function is:
y=30/x
Answer:
w=5h-8
Step-by-step explanation:
Take the original formula h=(1/5)w+(8/5)
Subtract -8/5 on both sides to isolate the w, so h-8/5=(1/5)w
Now you have to get rid of the 1/5, so multiply 5(h-8/5), the 5 in the 8/5 cross each other out. You are left with 5h-8
Probably D because it started out as negative and then kept going up to positive
Area = length × width
Joseph: 12 × 9 = 108 feet
Alana: 25 × 7 = 175 feet
175 feet - 108 feet = 67 feet
Answer: Alana's garden is greater by 67 feet compared to Joseph's
