Question 877550
2) to find intersection point, set the functions equal to each other.
(m/10)*x + m  =  m/x
Multiply both sides of = by x
(m/10)*x^2 + mx = m
mx^2/10 +mx = m
Multiply both sides of = by 10
mx^2 + 10mx = 10m
mx^2 + 10mx - 10m = 0
Divide both sides of = by m
x^2 + 10x - 10 = 0
x^2 + 10x + 25 = 10 + 25
(x+5)^2 = 35
x+5 = square root(35)
x = square root(35) - 5
x = -square root (35) - 5
3) mx + 4 = 4/x
Multiply both sides of = by x
mx^2 + 4x = 4
mx^2 + 4x + 4 = 8
m = 1
(x+2)^2 = 8
x+2 = square root (8)
x+2 = 2*square root(2)
x = 2*square root (2) - 2
x = -2*square root (2) - 2
