The answer is D. If you plug in -6 for x (the x-value where the asymptote lies), only this equation will yield 1/0 for x=6. This means that D is the correct answer.
Use the quadratic formula to solve. the answer is the third one down
x= -sqrt10 - 4 and sqrt10 - 4
or in their notation above x= -4+/-10--sqrt
A represents the speed of the aircraft.
b represents the speed of the bus.
a=2b-5
114/b=218/a
Substitution method
114/b=218/(2b-5)
(2b-5)*(114/b)= 218
(228b-570)/b = 218
228b-570= 218b
228b-218b=570
10b= 570
b=57
Plug the value of b into one of the original equations.
a=2(57)-5
a=114-5
a=109
Final answer:
Average speed of plane= 109
Average speed of bus= 57
Answer:
148 in^2
Step-by-step explanation:
2(4 x 5) = 40
2(4 x 6) = 48
2(5 x 6) = 60
