Find the centroid for an area defined by the equations y = x² + 3 and y = - (x – 2)² + 7
sergeinik [125]
First we need to find where the 2 graphs intercept.

x^2 + 3 = - (x^2 - 4x + 4) + 7
x^2 + 3 = -x^2 + 4x + 3
2x^2 - 4x = 0 
2x(x - 2)

x = 0 , 2. are x coordinates  of the 2 intercepts.

Is -100 rational or irational
pychu [463]

-100 is rational.

-100 can be turned into a fraction by doing the following...

Just put 1 underneath -100 and you get \frac{-100}{1}

So that means it is rational since it can be a fraction!

what is the y-intercept of the equation of the line that is perpendicular to the line y=3/5x+10 and passes through the point (15
ohaa [14]

The slope of the given line is the coefficient of x, 3/5. The slope of the perpendicular line will be the negative reciprocal of that: -1/(3/5) = -5/3.

The point-slope form of the equation for a line of slope m through point (h, k) can be written ...

... y = m(x -h) +k

For your point and the slope found above, this becomes

... y = (-5/3)(x -15) -5

When x=0, this is

... y = (-5/3)(-15) -5 = 20

The y-intercept is 20.

Math help please help me with this page
White raven [17]
Please, post just one problem at a time, or (if you post more than one), indicate which one you want to focus on first.  Even more important, please do whatever you can to get started on each problem; I'm sure you know at least some basics.

What does "intersecting" mean?  Look it up if you're not sure.

Then what would "two intersecting lines" look like?  Draw the graph, or at least explain in words what the graph would look like.
