Plug 6 for x.
f(6) = 6^2 / 3 + 6
f(6) = 36 / 3 + 6
f(6) = 12 + 6
f(6) = 18
Car A Car B
d=rt d = rt
d = ra * 2.4 d = rb 4
ra = rb+22
distances are the same so set the equations equal
ra * 2.4 =rb *4
substitue in for ra
(rb+22) 2.4 =rb *4
distribute
2.4 rb +52.8 = 4 rb
subtract 2.4 rb from each side
52.8 = 1.6 rb
33 = rb
Car b travels at 33 miles per hour
Car a = 33+22
Car a = 55 miles per hour
C=x.19+.25
C means the total cost
X means the extra minutes
Answer:
=−5.75x−17.4
Step-by-step explanation:
=−0.25x−8+−1(5.5x+9.4)
=−0.25x+−8+−1(5.5x)+(−1)(9.4)
=−0.25x+−8+−5.5x+−9.4
another way >>>><<<<
=−0.25x+−8+−5.5x+−9.4
=(−0.25x+−5.5x)+(−8+−9.4)
=−5.75x+−17.4
Answer:
=−5.75x−17.4
Answer:
5/10 and .5
Step-by-step explanation:
