Please answer one question asap <br>A(-4,3) B(2,-1) D(-4,-1) C(2,-5)
Leni [432]

Answer:

Step-by-step explanation:

Vertices of the given quadrilateral are A(-4, 3), B(2, -1), C(2, -5) and D(-4, -1)

Since, slope of a line passing through two points (x_1,y_1) and (x_2,y_2) is given by,

Slope = \frac{y_2-y_1}{x_2-x_1}

Slope of AB = \frac{3+1}{-4-2}

                    = -\frac{2}{3}

Slope of AD = \frac{3+1}{-4+4}

                    = Not defined (Parallel to y-axis)

Slope of DC = \frac{-5+1}{2+4}

                     = -\frac{2}{3}

Slope of BC = \frac{-1+5}{2-2}

                   = Not defined (Parallel to y-axis)

Slope of AB = slope of DC = -\frac{2}{3}

Slope of BC = slope of AD = Not defined (parallel to y-axis)

As per property of a parallelogram,

"Opposite sides of a parallelogram are parallel and equal in measure"                  

Therefore, ABCD is a parallelogram.

X. F(x)
Mkey [24]

Answer:

  • A.  There is a line symmetry at x=1.5
  • D.  There are x- intercepts at (-1,0) and (4,0)

Step-by-step explanation:

The average of x-coordinates corresponding to the same F(x) value is 1.5. That is ...

  (-2+5)/2 = (-1+4)/2 = (0+3)/2 = 1.5

The values in the table appear to be symmetrical about x=1.5, so that is a line of symmetry.

__

The x-intercept points are those points where F(x) = 0: (-1, 0) and (4, 0).

__

The y-intercept is (0, -4), not (-4, 0).

On the interval [0, 5] the function is both decreasing and increasing.
