In 12 minutes it traveled 120 miles. So, it is going at 10 miles per minute.
Answer:
(2x - 3)/(x-2)
Step-by-step explanation:
divide the given equations :
(2x^2 +x -6) / (x^2 -4)
but first do some rearrangements
x^2 - 4 = (x - 2) × (x + 2)
and
(2x^2 + x - 6) = (2x -3) × (x + 2)
when you write the whole equation as a fraction
(x+2) will be eliminated from both sides and only (2x - 3)/(x - 2) will be left
we can't do further calculations so it's the simplest way to write it
Answer:
option A would be correct.
Step-by-step explanation:
The only pairs of function and satisfying (f•g)(x)=x.
Check:
= = .
(f•g)(x)=x.
Therefore, from the options only Option A would be the required answer
Answer:
C. √105
Step-by-step explanation:
105 = 3·5·7 has no square factors, so its root cannot be simplified.
√105 simplified is √105.
