Height of the Volleyball Serve What does the point (1, 18) represent in the context of the problem?
A) The ball is 1 foot in the air after 18 seconds.
B) The ball is 18 feet in the air after 1 second,
C) It takes 18 seconds for the ball to hit the ground.
D) There are 18 players on the court in the first game.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
