42 = -6 + 3x
42 = 3x - 6      (just moving 3x and -6 around)
42+ 6 = 3x - 6 + 6     (adding 6 to both sides)
42 = 3x    
42/3 = 3x/3    (dividing by 3 to both sides to isolate for x)
14 = x

You're trying to isolate for x, so you have to get it alone on one side. To do this you have to add/subtract and multiply/divide, but remember that whatever you do to one side you have to do to the other. Hope this helped! :)

2. Assume f(x) = g(x). Which of the following functions may be used to represent the equation 3x+2 = 7x + 6? A. f(x) = x + 2, g(
charle [14.2K]

Answer:

C. f(x) = 3·x + 2, g(x) = 7·x + 6

Step-by-step explanation:

The given equations relates to the property of equality of values;

The given formula for the association between f(x) and g(x) is f(x) = g(x)

The given equation of two expressions is 3·x + 2 = 7·x + 6

By transitive property of equality, the two above equations are correct when f(x) = 3·x + 2 and g(x) = 7·x + 6

Therefore, the function that may be used to represent the equation is option C; f(x) = 3·x + 2, g(x) = 7·x + 6.

Determine whether the graph of y^5=x^3 is symmetric with respect to the Y axis the x-axis or the origin.
zhannawk [14.2K]

9514 1404 393

Answer:

  the origin

Step-by-step explanation:

Both terms are of odd degree, so the function is an odd function. It is symmetrical with respect to the origin.

__

If you recast this as y = f(x), then ...

  f(x) = x^(3/5)

When we look at f(-x), we find ...

  f(-x) = ((-x)^3)^(1/5) = -(x^3)^(1/5) = -(x^(3/5)) = -f(x)

An odd root of a number has the same sign as the number.

When f(-x) = -f(x), the function is odd and symmetrical about the origin.
