Answer:
(-5,9+√8)
Step-by-step explanation:
There are two ways in which you can find a point that lies in the circle. One of them is to do y the subject of the formula, and another one is to determine the center of the circumference, and with the information of the radius, you can sum this value upward or downward.
the general equation of a circle is:

with center at (h,k)
you have the following equation:

Then, the center is (-5,9)
if you sum the value of the radius in one of the fourth directions (up, down, left, right), for example upward you have

Then, one point that lies in the circle is (-5,9+√8)
The slope intercept form is y=mx+b so u need the exact expression u can't complete a full equation
Answer:
the correct estimate of the weight of Errol's backpack would be 33
Step-by-step explanation:
you just need to add 10 and 23.
Supplementary angle must add up to 180 so the supplement will be 108 degrees. 180-72=108.
Here’s the work I think it should be right
