Answer:

g(x) = 3x + 4

and f(x) = \frac{3}{\sqrt{x}}

Step-by-step explanation:

The function y=\frac{3}{\sqrt{3x+4}}

has two possible f(x) and g(x).

If g(x) = 3x + 4

and f(x) = \frac{3}{\sqrt{x}}

OR, If g(x) = \sqrt{3x+4}}

and f(x) = \frac{3}{x}.

Further, f(g(x)) is the symbol of composition.

Well, your equation y=3/SQRT(3x+4) should be rationalized, but that's not what you want.

If f(x) = 3/SQRT(x+4) and g(x) = 3x

f(g(x)) then = 3/SQRT(3x+4), but rationalizing this = 3SQRT(3x+4)/(3x+4)

Midpoint R(-4,6) and S(2,7)
shusha [124]

To find the midpoint, Add the two X coordinates together then divde by two and then to the same with the Y coordinates:


X = -4 + 2 = -2 / 2 = -1


Y = 6+7 = 13/2


Midpoint = (-1,13/2)

Mrac [35]

Answer:

$98.33 was deposited in the account

Step-by-step explanation:

simple interest formula = (PRT)/100 ...where p is money, r is rate, t is time

using formula  $17.70 = (P *  3% * 6)/100

                         P = 1770/18

                         P = $98.33

What are these fractions in simplest form?
Anton [14]
\frac{16y^{3}}{20y^{4}} =  \frac{4}{5y}
\frac{6xy}{16y} =  \frac{3x}{8}
\frac{abc}{10abc} =  \frac{1}{10}
\frac{mn^{2}}{pm^{5}n} =  \frac{n}{pm^{4}}
\frac{12h^{3}k}{16h^{2}k^{2}} =  \frac{3h}{4k}
\frac{8x}{10y} =  \frac{4x}{5y}
\frac{24n^{2}}{28n} =  \frac{6n}{7}
\frac{30hxy}{54kxy}  =  \frac{5h}{9k}
\frac{5jh}{15jh^{3}} =  \frac{1}{3h^{2}}
\frac{20s^{2}t^{3}}{16st^{5}} =  \frac{5s}{4t^{2}}

Number 31 please guys!!!!!
monitta
the answer is c
this is because, first you use the distributive property. Multiply 'y' by the number 3 and you get 3y
then multiply 3 by the number 4.
you get 12
subtract 7 from 12 and you get 5

So, the expression becomes 3y+5


Hope this helped!!
