Answer:
-5+b or b-5
Step-by-step explanation:
Answer:
- 2
Step-by-step explanation:
1) Write the equation in slope-intercept form.
4x - 8y = 64
-8y = -4x +64
y = 1/2 x - 8
slope of this line = 1/2
2) For perpendicular line the slope is negative reciprocal.
So, slope for perpendicular line is equal -2.

Answer:
b. 6.28 units
Step-by-step explanation:
The travel through 360° takes you around the full circumference of the circle. That circumference is ...
C = 2πr
Since this is a unit circle, the radius is 1, so the circumference is ...
C = 2π·1 = 2π ≈ 6.28 . . . units (counterclockwise)
Angles are generally considered to be positive in the counterclockwise direction, so the distance traveled is 6.28 units counterclockwise. Answer choice (a) has the correct number of units, but the direction is incorrect.
