Pretty sure its C. equal to
Step-by-step explanation:
In physics, potential energy is changed into kinetic energy while an object moves. this energy isn't lost, but simply changed into kinetic energy.
So, if the question is referring to the puck being in mid-air after the drop, then its definitely C.
Answer:
(-3, -7)
Step-by-step explanation:
y = 4x + 5
y = x - 4
add 4 to both sides of the second equation to get y + 4 = x
plug that back into the equation to get y = 4(y + 4) +5
distribute to get y = 4y + 16 + 5
combine like terms y = 4y + 21
subtract 4y on both sides to get -3y = 21
divide both sides by -3 to get y = -7
plug -7 into the second equation to get -7 = x - 4
add 4 on both sides to get -3 = x
therefore (-3, -7)
