Answer:
1/6
Step-by-step explanation:
Okay, we can use the functions in parts 3 and 4 since we want to calculate how many points will be deducted for 3 falls and how many points are earned for 4 seconds on the rail trick.
Part 3 function:
He fell 3 times, so plug this in for 'x':
Multiply:
So he will receive a 4.8 point deduction for falling 3 times.
Part 4 function:
Where 'x' is the seconds he does the trick. He did it for 4 seconds, so let's plug that in for 'x':
Multiply:
Add:
So he will receive 38 points for the 4-second rail trick.
First you need to combine like terms
13x+8-15x=6+x+11
-2x+8=x+17
-x -8 -x -8
-3x=9
--- ----
-3 -3
x=-3
