Answer:
-13
Step-by-step explanation:
(-1/3)*6 = -2
f(-1/3) = -2 -11
f(-1/3) = -13
Th correct answer would be D
2/5=4/10=12/30 1/3=10/30 12/30+10/30=22/30 22/30=11/15
Answer:
11) Here given Function,

And, 
For f(x) = g(x)






When we solve this equation,
We found,
x = 12.5227 ≈ 12.53
Thus, the required solution is, x = 12.53
12) Here the height of rocket A in x second,

And, The height gain by the rocket B in x seconds,

If at x seconds both A and B gain the same height,
That is, f(x) = g(x)
⇒ 
⇒
⇒ 
⇒ 
⇒ x = 1.125 ≈ 1.13
Thus, the required solution is x = 1.13 seconds (approx)
x+3
4+(x+2)
4
or
x+3 * 1
x+6 4
x+3
4x+24
