This works because of the addition property of equality
a=16--->a+3=16+3
reverse engineering
a+3=16+3--->a=16
now given that 5x-4y=-30
and given also the equation 3x+4y=38
by the addition property
3x+4y+(-30)=38+(-30)
since -30=5x-4y by substituting
3x+4y+(5x-4y)=38-30
which yields
8x=8
the addition property of equality which is B.

Help, this is a khan question so you may have done it before
Readme [11.4K]

Answer:

Eric, 9.8 meters.

Step-by-step explanation:

Use the distance formula with the given coordinate and each of the other coordinate.

\sqrt{(10-3)^{2}+(8-2)^{2} } Brooke

\sqrt{(-6-3)^{2}+(6-2)^{2} } Eric

\sqrt{(8-3)^{2}+(-6-2)^{2} } Cam

You'll see that Eric kicked the furthest distance with a distance of 9.8 meters.

Brooke kicked 9.2 meters and Cam kicked 9.4 meters. What does the distance formula really mean? When you solve for the distance between two points, you're really just creating a triangle between those two points, and you're actually looking for the hypotenuse. The slope that intersects your two points is the hypotenuse of the triangle you created.
