direct variation

y = kx

substitute in and solve for k

14 = k(-4)

14/-4 =k

k = -7/2


y = -7/2 x

y = -7/2 * -6

y = 42/2 = 21

What is the length of the third side of the window frame below? (Figure is not drawn to scale.) A picture of a right triangular
mina [271]
By the Pythagorean Theorem,  the longest side of a right triangle squared is equal to the sum of the squared sides...

h^2=x^2+y^2, where h=hypontenuse, and x and y are the side lengths...

87^2=w^2+63^2

w^2=87^2-63^2

w^2=3600

w=√3600

w=60 in

So the base of the frame is 60 inches wide.
