Step-by-step explanation:
Albert: 60% of 30= 18
Anthony: 40% of 30= 12
18 - 12= 6
2x + 3y = 6.....multiply by 3
-3x + 5y = 10...multiply by 2
-----------------
6x + 9y = 18 (result of multiplying by 3)
-6x + 10y = 20 (result of multiplying by 2)
-----------------add
19y = 38
y = 38/19
y = 2
2x + 3y = 6
2x + 3(2) = 6
2x + 6 = 6
2x = 6 - 6
2x = 0
x = 0
solution is : (0,2)

Step-by-step explanation:
The x intercept is when the line goes through the x axis.
1 + i? I think. Because they are both negative because you aren't actually subtracting just adding a negative
X³ - 1 = x³ - 1³ = (x-1)(x²+x+1)
