Question 208025: the lines f(x)= ax+b and g(x)=bx-a are perpendicular lines
a.) f(0)*g(0)
b.) if g(1)/f(0)=5 a>0 what is the value of a?

You can put this solution on YOUR website!
the lines f(x)= ax+b and g(x)=bx-a are perpendicular lines
f(0) = b ; g(0) = -a
-----------------------------
a.) f(0)*g(0) = b*-a = -ab
------------------------
b.) if g(1)/f(0)=5 a>0 what is the value of a?
(b-a)/b = 5
b-a = 5b
a = -4b
