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) = \frac{3}{x+1}

Therefore, h(-2) = \frac{3}{-2+1}

                          = -3

(h o k)(2) = -3 is the answer.

Option (D) is the correct option.

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

He solution is n = –2 verified as a solution to the equation 1.4n + 2 = 2n + 3.2. What is the last line of the justification?
Nimfa-mama [501]

Answer:

-0.8=-0.8

Step-by-step explanation:

We have been given that n=-2 verified as a solution to the equation 1.4n+2=2n+3.2.

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.

1.4*-2+2=2*-2+3.2

-2.8+2=-4+3.2

-0.8=-0.8

Since the value of n satisfies our equation, therefore, last line of the justification will be -0.8=-0.8.
