If h(x) = 5 + x and k(x)= 1/x, which expression is equivalent to (kxh)(x)?

It can be solve this in two ways,

1) as if the h(x) = 5x and 2) as if h(x) = 5 + x

1) If h(x) = 5x and k(x) = 1/x

Then (k o h) (x) = k ( h(x) ) = k(5x) = 1/(5x)

2) If h(x) = 5 + x and k (x) = 1/x

Then (k x h)(x) =k ( h(x) ) = k (5+x) =  1 / [5 + x]

1/(5+x) is the correct answer

Step-by-step explanation:

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

ratio is 2 : 9

the answer is three

13.5 : 3
