The domain is the set of feasible inputs, i.e. the x-coordinates in which you can evaluate the function.
We can see that this function is defined only for x values between -1 and 3 (included), so this is your domain.
Answer:
X > - 7.5
Step-by-step explanation:
1/X + 1/3 < 1/5
1/X + 1/3 < 1/5
Step one:collect like terms
1/X < 1/5 -1/3
Step two: Find the L.C.M of the R.H.S which is 15
1/X < 3-5/15
1/X < -2/15
1/X < -2/15
Step three: Take the reciprocal of both sides.
X < 15/-2
Dividing through by -2 changes the inequality sign, Hence
X > -7.5
C is when both are negative
2017 = 2 hrs x 60 mins = 120 mins
2016 = 8/11 x 120 mins = 87.27 mins
2015 = 9/12 x 120 mins = 90 mins
Therefore, Fatema ran the fastest in 2016.
Answer:
False because both 2 and 8, and 3 and 5 are alternate interior angles
