The graph shows the solution to which system of equations?
Sedaia [141]
So let's start by guesstimating the slopes:
the green line has a slope close to -x, but more negative than that, possibly -2; the pink line has a slope close to +x, but higher towards +2.

Next let's look at the solution: the two lines intersect at the point (1, -1).
**you could just simple plug that x (1) into all the equations, but let's rule out answers anyway. ;)

A) is incorrect because the slopes of -1 and +1 are off from out predicted -2 and +2
B) is incorrect because of a similar reason, the slopes of +3 and +1 don't make any sense
C) Ooh, we do have a +2 and -2 for the slopes, and... violà! plug in 1 for the x's and we get -1 for the y in both equations
D) slopes are closer than in A and B, but plugging in 1 doesn't get us -1

So the correct answer is:
C) y = 2x - 3 and y = −2x + 1

A tennis ball is hit into the air with a racket when is the balls kinetic energy he greatest ignore the air resistance
Veronika [31]

Kinetic energy is the energy of an object in motion.

The tennis ball would create kinetic energy as it was both traveling up to it's maximum height and as it was falling back down to the ground.

Because of gravity, the kinetic force would be greater as it was falling back to the ground though.

The answer would be B) just before it reaches the ground.
