Step-by-step explanation:
if x=2 and y=2 and radius=2
(x_2)2. +(y_2)2 =2x2
x2 -4x+4 +y2 -4y+4=4
x2 +y2 -4x- 4y +8-4=0
x2 +y2 -4x -4y +4=0
Answer:
-1.
Step-by-step explanation:
The standard form of a line can be written y = mx + b where m is the slope.
y = x + 5 can be written as y = 1x + 5 which shows that the slope is 1.
If the slope of a line is m then the slope of a line perpendicular to it is -1/m.
So the required slope is -1/1 = -1.

Step-by-step explanation:
Answer:
x = 9
Step-by-step explanation:
84 + (7x + 5) + (180 - (17x-1)) = 180
84 + 7x + 5 + (181 - 17x) = 180
270 + (-10x) = 180
90 = 10x
x = 9
