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.
Answer:
1 solution
Step-by-step explanation:
Given
- 3n = - 10 - 2n ( add 2n to both sides )
- n = - 10 ( multiply both sides by - 1 )
n = 10
The <em>correct answers</em> are:
40 songs;
48 songs; and
56 songs.
Explanation:
Since each class sings 8 songs per week, to find the number of songs for any given number of weeks, we multiply:
8 songs per week * 5 weeks = 40 songs
8 songs per week * 6 weeks = 48 songs
8 songs per week * 7 weeks = 56 songs
