5x = 10
we want to add these equations
5x = 10
if we divide by 5 on each side
5x/5 = 10/5
now we can find y
2(2) +y = 4
subtract 4 from each side
4-4 +y = 4-4
bill suffered a loss of 42.85%.
bill bought a home for $210000 and sold it for $120000 and we have to calculate the percentage loss he suffered.
as we know loss suffered = difference of sale price and cost price of the home.
total loss = 210000-120000 = $90000
now percentage loss =
= 9/21×100 = 3×100/7 = 42.85%
so the answer is 42.85% loss.
given is a function
this function is a parabola with vertex at (2,0) and axis of symmetry is x=2
hence for x< 2 the curve would be reflection of x> 2
to get inverse we must get one to one funciton only.
so restrict the domain of f(x) to
then we have f(x) as one to one with domain x≥2 and range is r+
for this inverse domain is r+ and range is
