Work Shown:
7y+3c=9y+12-2y+3
7y+3c=(9y-2y)+(12+3)
7y+3c=7y+15
3c=15
c = 15/3
c = 5
The steps above show that the y terms cancel. Solving for c leads to 5. If c is this value, then the original left and right hand sides are identical. Two sides being identical lead to infinitely many solutions. If , then there are no solutions for y.
Answer:
60 feet
Step-by-step explanation:
The height, h (in meters), of the object launched from a platform is represented by the equation
where x is the time (in seconds) passed after the launch.
The time of launch is (0 seconds passed after the launch)
Substitute to find the height:
