Yes, because AB and CD are parallel and GH is perpendicular to CD, AB is perpendicular to GH. So you are right.
-2n(5 + n - 8 - 3n) = -2n(-3 - 2n) = 6n + 4n²
n = 3, subtitute
6 · 3 + 4 · 3² = 18 + 4 · 9 = 18 + 36 = 54
Answer:
1/3
Step-by-step explanation:
Y/x=k that is the equation for constant of proportionality
2/6=k
1/3=k
Answer:
Andre has the correct answer. When simplified his answer is equivalent to the original equation.
Let x be the time in hours it takes to go 80 miles. Set v(t) = 80.
∫v(t)dt = 80 from 0 to x
Then 80x - 80(0) = 80
80x = 80
x = 1 hour
