Answer:

The x intercept is (-5,0)

Step-by-step explanation:

1. First, it would be helpful to rewrite the equation to be in y=mx+b form.

5y=4x+20

y=(4/5)x+4

2. Then, plug in 0 for y.

0=(4/5)x+4

3. Then, solve.

-4=(4/5)x

-20=4x

x=-5

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.
