Answer:

x=-3

Step-by-step explanation:

So, we are given:

\frac{3}{x}=\frac{4x+3}{x^2}

First, we should immediately rule out 0 as an answer. This is because the if x=0, the equation would be undefined.

x\neq 0

Now, cross multiply.

3(x^2)=x(4x+3)

3x^2=4x^2+3x

Divide everything by x (and we can do this safely because we already know x cannot be equal to zero).

3x=4x+3

-x=3

x=-3

We didn't run into any possibilities for extraneous solutions.

Match each function with the corresponding function formula when h(x) = 5 - 3x and g(x) = -3 x + 5.
laila [671]

Answer:

To match each functions with the corresponding function formula when h(x) = 5 - 3x and g(x) = -3 x + 5.

1. k(x) = (3h - 5g)(x)

  = = 3(5 - 3x)-5(-3 x + 5)

 = = 15 - 9x + 15x - 25

  K(x) = -10 + 6x

2.  k(x) = (h - g)(x)

    = = (5 - 3x) - (-3 x + 5)

 = = 0

k(x) = 0

3. k(x) = (5g + 3h)(x)

 = = 5(-3 x + 5)+3(5 - 3x)

 = = -15x + 25 + 15 - 9x

 k(x) = - 24x +40

4. k(x) = (3g + 5h)(x)

  =  = 3 (-3 x + 5) + 5(5 - 3x)

 = = -9x + 15 +25 -15x

 k(x) = -24x + 40

5.  k(x) = (g + h)(x)

   = = (-3 x + 5) + (5 - 3x)

k(x)  = -6x + 10

6.  k(x) = (5h - 3g)(x)

 = = 5(5 - 3x) - 3(-3 x + 5)

= =25 - 15x + 9x - 15

k(x) = 10 - 6x
