30 = 80*t
t = 30/80 = 3/8 hr
3/8 hr * 60 min/hr = 180/8 = 22.5 min
C = 11*(2*d) Try it and see that it fits every sample you have. Again this can be simplified to
C = 22 * d
Expand: 4x+8-3x+6
simplify: x+14
Answer:
−3 x −6
Step-by-step explanation:
The domain is {-7,-5,-3,0,7}.
The range is {-1,-1,2,3,6}.
:) hope you get a good grade.
