Answer:
x=4 x=-1
Step-by-step explanation:
x^2-3x-4=0
x^2-4x+x-4=0
x(x-4) + 1(x-4)=0
x+1=0
x=-1
x-4=0
x=4
Slope formula:
m = y2 - y1 / x2 - x1
Line QR: (2,8) (3,10)
m = 10 - 8 / 3 - 2 = 2 / 1 = 2
Line ST: (0,6) (-2,2)
m = 2 - 6 / -2 - 0 = -4/-2 = 2
<span>c. parallel because the slopes are the same</span>
Answer:
He must start his journey by 11 AM
Step-by-step explanation:
Speed of Toshi while walking up the mountains is 1.5 kilometres per hour
Speed of Toshi while walking down the mountains = 2 * Speed of Toshi while walking up the mountains = 3 kilometres per hour
Time taken to travel 9 Km in the upward direction by Toshi = 9 Km/1.5 kilometres per hour = 6 hours
Time taken to travel 9 Km in the downward direction by Toshi = 9 Km/3 kilometres per hour = 3 hours
He will take total 6 hours + 3 hours = 9 hours to travel 18 Km distance
Thus, He must start his journey by 11 AM
The whole numbers add up to 100. So now we are left with 1/2 or 0.5, 3/5 or .60, and 1/8 or .125. Those add up to 1.225 so the amount of sand in pounds in the wheelbarrow is 101.225. Hope I helped! If you have any questions just leave a comment.
