Inverse variation is of the form y=k/x (direct variation is of the form y=kx)

We are given that x=2 when y=1 so using the inverse form y=k/x we can solve for the constant of variation...

1=k/2

k=2

so the equation is:

y=2/x now they want us to find y when x=-1 so

y=2/-1

y=-2

A=12h(b1+b2) solve for b1 please.

Papessa [141]

A = 12h(B1 + B2)
A = 12h(B1) + 12h(B2)
A - 12h(B2) = 12h(B1)

B1 = $\frac{A - 12h(B1)}{12h}$
