The coordinates of the vertex of the parabola given by the equation: y = x^2 - 2x - 2 is ( 1 , - 3 ) . y = x^2 - 2x - 2 y = ( x - 1 )^2 - 3 when x = 1 , y = -3 .

This answer has been confirmed as correct and helpful.

Weegy: Let 3x - y = 13 be equation 1 and
2x + y = 12 be eqaution two. [
On adding equation 1 and 2 the resultant equation is 5x = 25
therefore, x = 25/5
x = 5.
Now putting the value of x in any of the above equations(equtaion 1 or 2) we get the value of y.
3(5) - y = 13
15 - y = 13
Taking y on the right hand side and 13 on the left hand side of the equality the equation becomes
y = 2.
Therefore, x = 5 and y = 2. ] (More)
