Whitepunk [10]

Answer:

The correct answer is:    [C]:

________________________________________________

  " {The figure is a kite.  To be a parallelogram, it would have to have pairs of <em>opposite</em> congruent sides, not just congruent sides. } ."

________________________________________________

Step-by-step explanation:

________________________________________________

Note that "all" squares are "parallelograms" ; and that "all" rectangles are

                "parallelograms" ;  

           yet:  "Not All parallelograms" are "squares" or "rectangles".

________________________________________________

The question asks:

________________________________________________

"Quadrilateral QRST has two pairs of congruent  sides, but it is not a parallelogram.  

What figure is it?  

What further condition would have to satisfy to be a parallelogram? "  .

________________________________________________

So;  we can rule out:

________________________________________________

"Answer choices:

[A]:  "The figure is a square..." ;

________________________________________________

[B]:   "The figure is a rectangle..." ;  <em><u>AND</u></em> :

________________________________________________

[D]: "The figure is a square..."  .

________________________________________________

We are left with:

________________________________________________

Answer choice:  [C]:  

________________________________________________

          " { The figure is a kite.  To be a parallelogram, it would have to have pairs of <em>opposite</em> congruent sides, not just congruent sides. } "  .

Y=1/3x what is the slope
Karolina [17]

Answer:

Slope = \frac{1}{3}

Step-by-step explanation:

The equation for finding slope is:

y = mx+b

In the equation, m is the slope, x is the x-intercept, and b is the y-intercept. The number next to x is ALWAYS the slope.

Your equation:

y = \frac{1}{3} x

The number(fraction) next to x is \frac{1}{3}. Therefore, your answer will be \frac{1}{3}
