Answer:
slope : -5/2
y-inter : 2
Step-by-step explanation:
-5x - 2y = -4
-2y = 5x - 4
-2y/-2 = 5x/-2 - 4/-2
y. = -5/2x + 2
Answer:
30 km/h
Step-by-step explanation:
usual speed= x km/h
increased speed= x +10 km/h
distance= 360 km
time difference= 3 h
- 360/x= 360/(x+10) +3
- 360/x= (360+ 3x+30)/(x+10)
- 360(x+10)= x(390+3x)
- 360x+3600= 390x+ 3x²
- 3x² + 30 x -3600=0
- x²+10x-1200=0
- x=30 km/h
Answer:
I believe the median is 47. I hope this helps!
Step-by-step explanation:
Answer:
Step-by-step explanation:
The angle formed by two secants is half the difference of intercepted arcs.
- 46 = 1/2(x - 57)
- x - 57 = 46*2
- x = 57 + 92
- x = 149
Correct choice is B
