Answer:
Tags not given out=(k/5)-40
Step-by-step explanation:
k is tag
Tags k given to student are half = k/2
Tags given to parents are= 100
Total tags given to students and parents are=(k/2)+100
So remaining tags are=k-(k/2+100)
=(k-200)/2
tags given to judges and teacher are 3/5 of remaining tags =(3/5)*((k-200)/2)
So tags not given out are =(2/5)*((k-200)/2)
=(k/5)-40 Answer

The y-coordinate of the solution is 11.
Both equations have y isolated. We will use substitution for this system:
5x-9=x²-3x+7
We want to gather all of the variables on one side, so we will subtract 5x from each side:
5x-9-5x=x²-3x+7-5x
-9=x²-8x+7
We want the equation to be equal to 0 to solve it, so we will add 9 to both sides:
-9+9=x²-8x+7+9
0=x²-8x+16
This is easy to factor; factors of 16 that sum to -8 are -4 and -4:
0=(x-4)(x-4)
Since these are the same factor, we solve it to get our answer:
x-4=0
x-4+4=0+4
x=4
Substitute this into the first, linear, equation:
y=5(4)-9=20-9=11
