Answer:
- D. y + 10 = 1/8* (x + 32)
Step-by-step explanation:
Use the given points to work out the equation of the line.
<u>Find the slope:</u>
- m = (- 10 - (-4)) / (- 32 - 16) = - 6 / - 48 = 1/8
<u>Use (-32, - 10) and point- slope form:</u>
- y - (- 10) = 1/8*(x - (-32))
- y + 10 = 1/8* (x + 32)
Correct choice is D
Let J = rate of jet in still airLet W = rate of wind Distance formula: d = rt / r = d/t Flying against the wind the jet flies at a rate of J - W = 1860 miles/3 hours = 620 miles per hourFlying with the wind the jet flies at a rate of J+W = 9180 miles/9 hours = 1020 miles per hour The average of these 2 rate is the speed of the jet in still air J = (620+1020)/2 = 820 miles per hour J - W = 620
820 - W = 620
W = 820 - 620 = 200 miles per hour The jet in still air flies at a rate of 820 mph(miles per hour)The wind speed is 200 mph(miles per hour)
