(-\infty,-2) \cup(2,\infty)

<h2>Explanation:</h2>

Remember you need to write complete questions in order to find exact answers. In this way you haven't provided any function, so I'll choose a quadratic function given by:

f(x)=x^2-4x

So we need to find the entire interval at which this function positive. Put another way:

f(x)>0

By using graphing tool, we get the graph shown below. As you can see:

  • The function decreases from x=-\infty \ to \ x=0
  • The function increases from x=0 \ to \ x=\infty
  • The graph of the function is a parabola that opens up.

But what is really importan in this problem is that:

  • The function is positive over the interval (-\infty,-2) \cup(2,\infty)

At this interval the function is positive, that is, f(x)>0

X=-4+y and -2x-5y=15
Scrat [10]

Answer:

x=-5, y=-1

Step-by-step explanation:

Substitute x=-4+y into -2x-5y=15. So we have

-2(-4+y)-5y=15

8-2y-5y=15

-7y=7

y=-1

And x is -4+y so x= -4+(-1)= -5.
