Answer:
Lines that are parallel have the same gradient.
Since the line is y=-5/6x-4,the gradient of the line parallel to this line is also -5/6.
So the equation of the line parallel to y=-5/6x-4 is y-(-2)=-5/6(x-(-6))--->y=-5/6x-7.
Lines that are perpendicular fulfill the requirement: gradient 1×gradient 2=-1 . Then once you find the gradient of the line, you can find the equation of the line.
Answer:
7 acres a day
Step-by-step explanation:
6x7=42, so if they planted 42 trees in 6 days, the 7 is the only number left.
Therefore, (drumroll please)
7!
2x(2x+1)(2x-1)... 2x((4x^2)-2x+2x-1)... 2x((4x^2)-1)... (8x^3)-2x ... so the answer would be the last one
