8x51. 8x50=? 8x5=40. 40 x 10 = 400 8x50=400. 8x1=8 400+8=408.
Find how fast it travels in one hour:
460 miles / 2 hours = 230 miles per hour.
A) Multiply the speed per hour by the number of hours:
230 x 8 = 1840 miles in 8 hours.
B) 230 x 20 = 4,600 miles in 20 hours.
C) 460 miles / 2 hours = 230 miles per hour.
X=40 degrees because it s on the circle. arc AD+arc DC=180 arc DC is 100 so AD is 80. That means x must be 40.
<span>perpendicular slope :
m1 * m2 = -1
1/2 * m2 = -1
m2 = -2
y = -2x + b
2 = -4 +b
b = 6
y = -2x + 6
