Given a triangle ABC at A = ( - 1, 3 ) B = ( 1, - 1 ) C = ( 2, 2 ) and if the triangle is rotated 90 ° clockwise about the point

lidiya [134]

Answer:

The coordinates of A' are (6,6).

Step-by-step explanation:

It is given that in triangle ABC, A = (-1, 3), B = (1, - 1) and C = (2, 2).

If a point is rotated 90 ° clockwise about the point ( a,b ), then

$(x,y)\rightarrow ((y-b)+a,-(x-a)+b)$

It is given that the triangle is rotated 90 ° clockwise about the point ( 4, 1 ). So, a=4 and b=1.

$(x,y)\rightarrow ((y-1)+4,-(x-4)+1)$

$(x,y)\rightarrow (y+3,-x+5)$

The coordinates of A are (-1,3), So, the coordinates of A' are

$A(-1,3)\rightarrow A'(3+3,-(-1)+5)$

$A(-1,3)\rightarrow A'(6,6)$

Therefore the coordinates of A' are (6,6).

Simplify the polynomial. Then find its value for the given value of the variable.

vekshin1

Answer:

Step-by-step explanation:

Simplified expression:

$3x^3 -x^3 +5x^3-9x^3$

$2x^3 +5x^3-9x^3$

$7x^3 -9x^3$

$-2x^3$

If x = -1, the value of the expression is:

$-2x^3$

$-2(-1^3)$

$-2(-1)$

$2$

Hope this helps!
