It should be 14x I believe
The angle measure of 3 is 165 degrees
D is your answer
plug in the x value and y value to the equation
when x = 1, and y = 4
-1 + 4 = 3
when x = 5, and y = 8
-5 + 8 = 3
hope this helps :D
13 mph
using d=rt you can set up 2 equations
48=(r+3)t
30= (r-3)t
solving these both for t and setting them equal warrants
48/(r+3) = 30/(r-3)
and with cross multiplication and distribution you get
48r-144=30r+90
solving for r you get r=13
