Substitute the value of y in the equation as -1,
(-1)^2-31(-1)-17 = 1+31-17 = 15
It is multiplied by to because the raidouis is double.
Basically you do 25.50 time .15 (15% is equal to .15) and you get 3.825 or $3.83
hope this helped
Answer:
See below
Step-by-step explanation:
1) x = 4
2) x = 12
3) x = 45
4) x= 5.56
5) x = 35/18
6) x = 3/2
7) x = 19/3
8) x = 3/35
9) x = 47/5
10) x+4 = 17/2 so x = 9/2
