Answer:

B. -  \frac{9}{8}

Step-by-step explanation:

\huge\frac{ - 2 {a}^{ - 3} {b}^{2}  }{a}  \\  \\ \huge  =  \frac{ - 2  {b}^{2}  }{a \times{a}^{ 3} }   \\  \\ \huge =  \frac{ - 2  {b}^{2}  }{{a}^{ 4} }   \\  \\  \huge =  \frac{ - 2 \times  {3}^{2} }{ {( - 2)}^{4} }  \\  \\   \huge=  \frac{ - 2 \times 9}{16}  \\  \\  \huge  \red{=  -  \frac{9}{8} }

What is the most precise term for quadrilateral ABCD with vertices A(3,1) , B(4,5) , C(7,5) , D(7,2) answer choices; A. KITE B.
SOVA2 [1]

Answer:

Step-by-step explanation:

Given are the vertices of a quadrilateral.

WE have to find the name of the quadrilateral

WE have slope of AC = (5-1)/(7-3) = 1

and slope of BD = (2-5)/(7-4) = -1

Since m1m2 =-1 we get

the diagonals cut at right angles

This property is special property for square, rhombus and kite only.

Let us check if diagonals bisect each other

Mid point of AC = (\frac{3+7}{2} ,\frac{1+5}{2} =(5,3)

Mid point of BD =(\frac{4+7}{2} ,\frac{2+5}{2} =\neq 5,3)

Since diagonals do not bisect this is neither rhombus nor square.

Only possibility is kite

Use the given conditions to write an equation for the line in point-slope form and slope-intercept form.
ehidna [41]

Answer:

  • y +5 = -5(x +6)
  • y = -5x -35

Step-by-step explanation:

For a line with slope m through point (h, k), the point-slope form of the equation is ...

  y -k = m(x -h)

For your point and slope, the line is ...

  y +5 = -5(x +6)

__

Adding -5 and simplifying puts this in slope-intercept form.

  y = -5x -30 -5

  y = -5x -35
