Answer:
still air = 815, wind = 40
Step-by-step explanation:
x+y=against
x-y=with
8(x+y)=6200
8(x-y)=6840
Divide 8.
x-y=775
x+y=855
Subtract. 2 from 1
2y=80
y=40
x=815
Hope this helps plz hit the crown :D
Answer:
p(x)= (x+1)(x+2)(x-3)(x-1)
then,multiplying two two terms
(x^2 +2x+x+2)(x^2-x-3x+3)
(x^2+3x+2)(x^2-4x+3)
x^4- 4x^3+3x^2 +3x^3-12x^2+9x+2x^2-8x+6)
x^4-x^3-7x^2+x+6
Y = mx + b, m = slope and b = y-intercept
Thus the answer is y = -3x + 7
