lets solve by substitution make x+y=1 into y= form -x both sides y=-x+1 5x+y=-6 plug in 5x+(-x+1)=-6 5x-x+1=-6 4x+1=-6 -1 both sides 4x=-7 ÷4 both sides x=-7/4 solve for y x+y=1 -7/4+y=1 +7/4 both sides y=11/4
check if it's correct on the second equation 5 (-7/4)+(11/4)=-6 -35/4+11/4=-6 -24/4=-6 -6=-6 answers are true
the farther you get from Earth, the less the gravitational force i, so if your in space,<em><u> </u></em><em><u>you will have more weight next to earth than you will next to the moon</u></em><em><u>.</u></em>
You start by subtracting: 16000-1200= 14800 Then you divide 14800 by how many feet the plane rises per minute 14800/945=16 minutes The answer is 16 minutes
