Suppose the a mountain bike that sells for $419 is on sale for 20.5% off. a. what will the bike cost before tax? b. what will the bike cost including tax? answer : ))

Regular price:  $419
Sale price:  (1-0.205)($419) = $333.11

The bike will cost $333.11 before tax.  You haven't shared the tax rate, but I can at least tell you that the cost of the bike after tax will be 

(1.00 + rate as a decimal fraction)*$333.11.

Example:  If the tax rate is 7.5%, then the bike will cost (1.00+0.075)*($333.11).

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

there is a hike in both the graphs so the graphs are increasing on their domain.x-intercept of log x and log 6x are differentthere is a vertical asymptote of both the graphs so there is no y-interceptas both the graphs are increasing so there is no horizontal asymptote
