Which shows a perfect square trinomial?

Answer:

Third choice.

Step-by-step explanation:

Trinomial means you have 3 terms.

You don't have 3 terms in first two choices so let's not look at them.

Anything of the form a^2x^2+2abxy+ b^2y^2 is a perfect square trinomial because it can be written as (ax+by)^2.

Let's this this:

(ax+by)^2

(ax+by)(ax+by)

Now foil!

First=ax(ax)=a^2x^2

Outer=ax*by=abxy

Inner=by*ax=abxy

Last=by*by=b^2y^2

Add together and this gives you a^2x^2+2abxy+b^2y^2.

So looking at third choice you can write it as 4^2x^2+24xy+3^2y^2.

Is 2*4*3 equal to 24?  If it is then you have your answer. It is.

We have our answer.

Answer:

The third choice is the one you want

Step-by-step explanation:

If we are to write the equation of a line perpendicular to WX, we first must determine what the slope of the WX is, because the line perpendicular to WX has a slope that is the flip of the slope of WX with the opposite sign.  Solving for y takes care of finding the slope of WX:

2x + y = -5 so

y = -2x - 5

The slope is -2.  That means that the reciprocal slope is 1/2.  Using that slope along with the coordinates x = -1 and y = -2, we first write the line using point-slope form and then solve it for y.  Start by filling in the m, the x value and the y value:

y - (-2) = \frac{1}{2}(x-(-1))

Getting rid of the double negatives gives us:

y+2=\frac{1}{2}(x+1)

Distributing then gives us:

y+2=\frac{1}{2}x+\frac{1}{2}

And finally solving for y (I am going to express the 2 on the left as 4/2 when I move it by subtraction in order to add those fractions):

y=\frac{1}{2}x+\frac{1}{2}-\frac{4}{2}

And the final equation in slope-intercept form is:

y=\frac{1}{2}x-\frac{3}{2}

Where
m
is the slope and

is a point the line passes through.
Substituting the slope and values from the point in the problem gives:
