=ln(1−x)1/2

=21ln(1−x)

∴ For the composite function to be defined 1−x>0

x<1

∴ Domain is (−∞,1)

What is the sale price to the nearest cent? $239 television; 10% discount

miv72 [106K]

Answer:

The sale price will be: $215.10

What is the value of y?

mrs_skeptik [129]

Ok so you would start by getting rid of the fraction. You should know the steps for that by now but here this is what it would look like
3y/4+10=2y/4 Simplify
3y/4+10=1y/2
10=-1y
I really simplified the last part but this is what it looks like: $\frac{2y}{4}$ - $\frac{3y}{4}$ = -1y
10=-1y
y=-10
