Answer:

x = - \frac{14}{3}

Step-by-step explanation:

Given

\frac{6x+3}{5} = 3x + 9 ( multiply through by 5 to clear the fraction )

6x + 3 = 15x + 45 ( subtract 15x from both sides )

- 9x + 3 = 45 ( subtract 3 from both sides )

- 9x = 42 ( divide both sides by - 9 )

x = \frac{42}{-9} = - \frac{14}{3}

If the domain of the square root function f(x) is x<7, which statement must be true?
Delicious77 [7]

Answer:

The x-term inside the radical has a negative coefficient

Step-by-step explanation:

The argument of a square root should be ALWAYS greater or equal to zero. If the domain of the function is x<7, rearranging, we have: 0<x-7

Therefore the argument is: x-7, and the function is: y = √(x-7)

The statement "The x-term inside the radical has a negative coefficient" is the right answer.
