There is a step missing from the solution below. which equation is the missing step? p=17-√0.025x+7 25=17-√0.025x+7 8=-√0.025x+7 ? 57=0.025x 2280= x a. 64=0.025x+49 b. 8=0.025x+7 c. -8= √0.025x+7 d. 64=0.025x+7

option: D is the correct answer.

( D. 64=0.025 x+7 )

Step-by-step explanation:

We are given step as:

?

57=0.025x

-----------(2)

2280= x.

We are asked to find the missing step.

Clearly after equation (1)

They have squared the equation both side to obtain:

and then they took the constant term to the left hand side to obtain equation (2).

Hence, the correct option is:

Option: D

D. 64=0.025 x+7

step-by-step explanation:

asnwer is (g o h o f)(x) = 2x - 6/x + 7

step-by-step explanation:

given,

f(x) = x - 3/x

g(x) = x + 3

h(x) = 2x + 1

we need to find : (g o h o f)(x)

we can write (g o h o f)(x) = g[ h{ f(x) } ]

so first we find h{f(x)}

h{f(x)} = f(x) + 3 = (x - 3/x) + 3

h{f(x)} = x - 3/x + 3

now we find g[ h{ f(x) } ].

g[ h{ f(x) } ] = g(x - 3/x + 3)       {plug h{f(x)} = x - 3/x + 3 in g[h{f(x)}] }

g(x - 3/x + 3) = 2 (x - 3/x + 3) + 1

                    = 2x - 6/x + 6 + 1

                    = 2x - 6/x + 7

hence we get (g o h o f)(x) = 2x - 6/x + 7
