0.2 y is inversely proportional to V1+x.
When x=8, y = 2.
Find y when x = 15.

Please help me with this real quick!

y = 1.5

Step-by-step explanation:

Given y is inversely proportional to , then the equation relating them is

y = ← k is the constant of variation

To find k use the condition when x = 8, y = 2 , then

2 = = = ( multiply both sides by 3 )

6 = k

y = ← equation of variation

When x = 15, then

y = = = = 1.5

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
