Angle 1=37
Answer:
Option A Center (5,-4) radius 7
Step-by-step explanation:
x^2 +y^2 - 10x +8y - 8= 0
Center(-g,-f)
2gx = - 10x
g = - 5
2fy = 8y
f = 4
Center (5,-4)
Radius = square root of (g^2+f^2 - c)
r = square root of (5^2 + - 4^2 - (-8))
r = square root of (25+16+8)
r = square root of 49
r = 7

Answer:
6b+b^2 (b to the 2nd power)
Step-by-step explanation:
8b+b^2-2b (b to the 2nd power)
(8b-2b)+b^2
6b+b^2

Answer: No slope / undefined
Step-by-step explanation:
Concept:
Here, we need to know the idea of a slope.
The slope is the measure of the steepness of a line.
The basic formula of slope is [Rise / Run] which is basically [Y] value (vertical) over [X] value (horizontal)
If you are still confused, please refer to the attachment below for the full formula.
Solve:
(7 ,1)
(7, -2)
Slope = (1 - (-2)) / (7-7)
Slope = (3) / 0
Slope = Undefined
Indeed, it is a vertical line. By definition, a vertical line has no slope.
Hope this helps!! :)
