Determine the coordinates of the point $P$ on the line $y=-x+6$ such that $P$ is equidistant from the points $A(10,-10)$ and $O(

0,0)$ (that is, so that $PA=PO$). Express your answer as an ordered pair $(a,b)$.

Answer:

P=(3,3)

Step-by-step explanation:

We need to find a point  P in the line y=-x+6 such that PA=P0 where A=(10,-10)

Observe that the coordinates of P are (x,y)=(x,-x+6) because P is in the line.

Then,

PA=P0\\(x,-x+6)(10,-10)=(x,-x+6)(0,0)\\10x+(-x+6)(-10)=0\\10x+10x-60=0\\20x=60\\x=3

We reeplace  the value of x in the coordinates of P and obtain the point

(3,-3+6)=(3,3)=P

Answer: 5:15:23 pm

Step-by-step explanation:

There are different time zones in the world due to the Earth's rotation as this results in different parts of the Earth receiving sunlight at different times.

GMT is used as a basis to find the times of other zones.

In this instance, EDT time is -4 that of GMT.

This means that EDT is 4 hours behind GMT.

Time in GMT is therefore:

=  1:15:23 + 4 hours

= 5:15:23 pm
