Answer:
3
Step-by-step explanation:
3(1)² - 5(1) + 1
3x3 = 9
9-5+1
9-6 = 3
$12.98 each. You would do $56.07 - $4.15. Then divide the answer of that by four.
Just place dots where the points are saying, the first number is always x aka the horizontal line ( the one that is going down) and the second number is y aka the vertical line ( the one going up)
First find x and y.
Solve system of equations by elimination.
3x-y=3
+(-x+y=3)
---------------
2x=6
x=3
Now plug in x into one of the equations to find y.
-3+y=3
y=6
xy=3x6=18
