The functions which are even are symmetric to y-axis. By even functions, it means that f(x) = f(x) for all the domain values. Thus even functions for example, x^2, 1+x^2, cosx, x^4 all follow the conditions i.e. f(x) = f(x) and thus they are symmterical to y-axis.
Answer:
C (900)
Step-by-step explanation:
50 for each orchestra
40 for each balcony
600 x 50 = 30000
39000/40 = 975
600+975=1575 not correct
750 x 50=37500
750 x 40 = 30000
not correct
900x50=45000
600x40=24000
correct
The answer is r greater than or equal to -3
Answer:
k = 27/4
Step-by-step explanation:
1/5 (k - 3) = 3/4
Multiply both sides by 5 or 5/1:
5 ⋅ 1/5 (k - 3) = 3 ⋅ 5/4
Simplify:
k - 3 = 15/4
Add 3 to both sides:
k - 3 + 3 = 15/4 + 3
Therefore:
k = 27/4
