Oceanside Bike Rental Shop charges a $15 flat fee plus $6 an hour for renting a bike. Dan paid $39 to rent a bike. Which equation can be used to find how many hours he rented the bike for? a 15x + 39 = 6

b 39x + 6 = 15

c 6x + 15 = 39

d 15x + 6 = 39

e6x + 39 = 15

f 39x + 15 = 6

Can someone me with my hwplz(only the circled ones)

The coordinates of a, b, and c in the diagram are a(p,4), b(6,1), and c(9,q). which equation correctly relates p and q? hint: since is perpendicular to , the slope of × the slope of = -1. a. p - q = 7 b. q - p = 7 c. -q - p = 7 d. p + q = 7

Aball is thrown from a height of 139 feet with an initial downward velocity of 15 ft/s. the ball's height h (in feet) after t seconds is given by the following. h=139-15t-16t^2 how long after the ball is thrown does it hit the ground? round your answer(s) to the nearest hundredth. (if there is more than one answer, use the "or" button.) t =
