Answer:
Step-by-step explanation:
The distance between two points is
d^2=(y2-y1)^2+(x2-x1)^2
D) points (0,0) and (9,12)
d^2=(9-0)^2+(12-0)^2
d^2=81+144
d^2=225
d=15
E) points (1,2) and (-3,5)
d^2=(-3-1)^2+(5-2)^2
d^2=16+9
d^2=25
d=5
Answer:
f ( x ) = 2 | − 3 | − 3
f (x) = 2 - 3 - 3
f (x) = -4
Step-by-step explanation:
I believe this is correct
Answer:
<u>B: x < -5</u>
- 2x - 7> x + 8
-3x - 7 > 8
-3x > 15
(switch sign when dividing or multiplying by a negative on opposite sides)
x < -5
Circumference = 2 * pi * radius
So, radius = circumference / (2 * pi)
