Answer:

D'(1,5)

Step-by-step explanation:

If you rotate a point 180 counter-clockwise around the origin, then it makes the x and y coordinates negative. In this case, it would make the coordinates positive because both coordinates are already negative. The answer would be D'(1,5).

Is the point (1, -3) a solution to the system? Show all work

Studentka2010 [4]

Answer:

The point P(1,-3) is not a solution to the system.

Step-by-step explanation:

Given $\left \{ {{y-x+2}} \right.$

Let a point be P(1,-3)

Here x = 1 ; y = -3

Substituting the values of x,y in the function

$\left \{ {{y-x+2}} \right.$

For y<x-1

-3 < 1-1

-3<0 (True)

now for,

y>-x+2

-3 > -1 + 2

-3 > 1 (False)

Hence the point is not a solution to the system.
