Stels [109]

Answer:

13. c,

14. a.

Step-by-step explanation:

13.  The length of a side PQ with coordinates of

      P as (x,y)  and Q as (w,z)

       is: \sqrt{(x-w)^{2} +(y-z)^{2} }

  • so, the length of the side AB =

\sqrt{(5-5)^{2}+(-2+7)^{2}  } =\sqrt{0^{2}+5^{2}  } =5

  • the length of side BC =

\sqrt{(5-1)^{2}+(-7+2)^{2}  } =\sqrt{(4)^{2}+(-5)^{2}  } =\sqrt{4^{2}+5^{2}  }

  • the length of side AC=

\sqrt{(5-1)^{2} +(-2+2)^{2} } =\sqrt{4^{2} } =4

now, the easiest one will be when the vertices are on the coordinate axes.

  • so, option c will be the most appropriate one.

14. If u see the figure clearly, the lines l and FH are parallel.

the parallel postulate, i.e, the alternate interior angles will always be congruent.

  • here, the alternate interior angles are angle1 and angle4.
  • therefore to prove this step, he used parallel postulate as a reason.
  • so, the correct option is "a"

Which Graph correctly solves the equation below? -1/2x^2 +2 = 2x^2 -8
lubasha [3.4K]

Answer:

see attachment

Step-by-step explanation:

The given equation is

-  \frac{1}{2}  {x}^{2}  + 2 = 2 {x}^{2}  - 8

The graph of the left hand side of this equation is

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

This quadratic graph has its vertex at (0,2) and turns upside down.

The right hand side of the equation is

y = 2 {x}^{2}  - 8

This quadratic graph opens upwards and has its vertex at (0,-8).

The two graphs intersects at two points , which are (-2,0) and (2,0).
