Answer:

x = 4

Step-by-step explanation:

Distributive Property: a(b + c) = (a*b) + (a*c)

           2x - 4(x - 3) = -8 + 5x - 8

2x + x * (-4) - 3*(-4) = -8 + 5x - 8

          2x - 4x + 12  = -8 + 5x - 8    

   2x -  4x - 5x + 12 = -8 - 8

               -7x  + 12  = -16

                       -7x  = -16  -12

                      -7x   = -28

                          x = -28/-7

x = 4

Find the domain of the rational function 9x/(x+5)(x+3)
xenn [34]

Answer:

the domain is : D = ]-∞ , -5[ U ]-5 , -3[ U ]-3 , +∞[

Step-by-step explanation:

hello :

f(x) = 9x/(x+5)(x+3)

f exist for : (x+5)(x+3) ≠ 0

(x+5)(x+3)=0

x+5=0 or x+3=0  means : x= - 5 or x= -3

the domain is : D = ]-∞ , -5[ U ]-5 , -3[ U ]-3 , +∞[
