After a rotation of 90° about the origin, the coordinates of the vertices of the image of a triangle are A'(6,3), B'(-2, 1)
Fed [463]

Answer:

  • A(3, -6)
  • B(1, 2)
  • C(7, -1)

Step-by-step explanation:

Rotation by -90° about the origin is the transformation ...

  (x, y) ⇒ (y, -x)

So, your pre-image points are ...

  A'(6, 3) ⇒ A(3, -6)

  B'(-2, 1) ⇒ B(1, 2)

  C'(1, 7) ⇒ C(7, -1)

The sides of a triangle have lengths 2x + 2, 4x, and 5x + 1. The longest side of the triangle has a length of 5x + 1. For what v
Savatey [412]

Answer:

Step-by-step explanation:

(5x+1)²>(2x+2)²+(4x)²

25x²+10x+1>4x²+8x+4+16x²

5x²+2x-3>0

5x²+5x-3x-3>0

5x(x+1)-3(x+1)>0

(x+1)(5x-3)>0

x+1=0,gives x=-1

5x-3=0,gives x=3/5

x >0(because 4x should be >0)

side is always positive.

so x>3/5

again 5x+1<2x+2+4x

5x-6x<2-1

-x<1

x>-1

x=all real values >3/5
