Answer:
Option D
Step-by-step explanation:
We have to find the value of the composite function (h o k)(2).
Since, (h o k)(x) = h[k(x)]
(h o k)(2) = h[k(2)]
From the picture attached,
At x = 2
k(2) = (-2)
Therefore, h[k(2)] = h(-2)
Since, h(x) = 
Therefore, h(-2) = 
= -3
(h o k)(2) = -3 is the answer.
Option (D) is the correct option.
Answer:
23 11/12 yards or 23.9166 yards
Step-by-step explanation:
2/3 of 100 yard race is equivalent to 66 2/3 yards. Tge difference between the above and 42 3/4 yards covered by tortoise will be
66 2/3- 42 3/4= 23 11/12 yards or 23.91666 yards
The mistake is n third line - adding 3w
96 + 2w =2(80 - 3w)
96 + 2w = 160 - 6w
+ 6w + 6w
96 + 8w = 160
- 96 -96
8w = 64
w = 8 weeks answer
Answer:

Step-by-step explanation:
We have been given that n=-2 verified as a solution to the equation
.
As n=-2 is the solution for our given equation, so it will satisfy our equation.
Let us substitute n=-2 is our given equation.



Since the value of n satisfies our equation, therefore, last line of the justification will be
.
I think it’s a im not that sure though
