X+y=8
multiply the first equation by 3 to get rid of x
3x+3y=24
3x+2y=14
subtract equation 1 from 2
y=10
substitute to find the value of x
x+10=8
x=-2
Hello,
1) Verify if it is a 2 degree.
2) y=ax²+bx+c
Calulate a,b,c by Gauss's methode
a=3, b=0,c=-1
y=3x²-1

Answer:
The price for one cone before tax is $2.26.
Step-by-step explanation:
The tax for each cone is $.17
Ronnie buys six cones. The total tax for the cones is 6 X $.17 = $1.02
Next, we subtract the total taxes from the total price $14.58 - $1.02 = $13.56
So Ronnie owed $13.56 for the six cones BEFORE taxes. We takes this amount and divide it by six to get the cost for one cone.
$13.56 / 6 = $2.26 per cone.
Check our work
Purchase one cone for $2.26 plus $.17 cents tax = $2.43 total cost per cone.
6 cones at $2.43 each would be 6 X $2.43 = $14.58.
This matches the total bill from the story problem.
