What is the constant of proportionality for y=9x

9

Step-by-step explanation:

Since the equation can be written in the form y=kx

, y varies directly with x and k. The constant of variation, k, is 9.

Hi there!

Area of a triangle:

A = 1/2(bh)

Plug in given values:

60 = 1/2(15h)

Solve for h. Multiply both sides by 2:

120 = 15h

Divide both sides by 15:

120/15 = h

h = 8 in
