Answer:
the false statement would be option b) (-333) < (-777).
Step-by-step explanation:
in negative numbers, the smallest negative number would be considered larger when compared to a large negative number. additionally, when you plot these numbers on a number line, it is evident that -333 would be closest to 0, and -777 would be the farthest. thus, -333 is larger than -777.

Answer:
Since speed is given in terms of "hours" we must convert 9 minutes to hours:
9 minutes = 9/60 hours = 3/20 hours
.
Let x = time (hours) it takes car to pass the truck
then
60(x + 3/20) = 69x
multiplying both sides by 20:
60(20x + 3) = 1380x
1200x + 180 = 1380x
180 = 180x
1 hour = x
Step-by-step explanation:
If ( x - 1 ) * ( x + 3 ) = 0 => x = 1 or x = -3;
But, (x-1)(x+3)=1 => x^2 + 3x -x - 3 = 1 => x^2 + 2x - 4 = 0;the discriminant is 2^2 - 4 * 1 * ( -4 ) = 20 => the solutions are x1 =
( - 2 +

) / 2 ; x2 = - 2 -

) / 2;
