f(x) = sqrt(x) - 2x.

The properties of the trapezoid are as follows:

The bases are parallel by definition.

Each lower base angle is supplementary to the upper base angle on the same side.

So, angle a + angle d = 180

         angle a = 2d    substitute

              2d +d = 180       d= 60

    a= 2d = 120 degrees                                    This assumes your trapezoid is labeled    A            B

                                                                                                                                          D                      C

Hope this helps~Hannah

By properties of trapzoids, angle C = 90 degrees, so angle B = 30 degrees.

Answer:

  y = 18.25

Step-by-step explanation:

The 2-point form of the equation of a line can be used to write the equation of the line through the given points.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (-2 -7)/(3 -(-1))(x -(-1)) +7

  y = -9/4(x +1) +7

For x = -6 this evaluates to ...

  y = -9/4(-6 +1) +7 = (9/4)(5) +7 = 45/4 +7

  y = 18 1/4

k(x) = -2x.

Just asking~Hannah

Cause:Over the course of the 19th century, rival powers of Europe formed alliances. Germany, Austria-Hungary, and Italy formed the Triple Alliance. Great Britain, France, and Russia formed theTriple Entente. Political instability and competition threatened those alliances. (Italy, for example, eventually entered World War I in opposition to Germany and Austria-Hungary.)

Effect:As many as 8.5 million soldiers and some 13 million civilians died during World War I.

Slope is -4x and the y intercept is 20

Sorry if it's not right,If it is right I hope it helped~Hannah

Its okay ill try and help you anyway :P

no sorry

Is there a graph?

 Slope of  the line = (-2 - 7)  / (3 - 1) =  -9 / 2

Equation of  this  line  is

y  = (-9/2) ( x - -1) + 7

y  = (-9/2)  ( x + 1)  + 7

y = -(9/2)x  - 9/2  + 14/2

y = -(9/2)x  + 5/4

When  x  = - 6

y =  -(9/2)(-6)  + 5/4

y = 54/2  + 5/4

y  = 113/4
