Answer:
x = -1/4, y = 5/4.
Step-by-step explanation:
Because of the absolute value equation y = |x - 1| the value of y must be positive.
Solving x - 1 = 3x + 2 :
2x = -3
x = -3/2 and y = -5/2 so x= -3/2 is not a solution.
x - 1 xcan also be negative so we have the equation
- (x - 1) = 3x + 2
1 - x = 3x + 2
-1 = 4x
x = -1/4
y = 1 - - 1/4 = 5/4.
The vertices are the intersections between the lines.
1) line x + y = 5 and y = 3:
y = 3 => x + 3 = 5 => x = 5 - 3 => x = 2
=> vertix = (2,3)
2) line x + y = 5 and y = 0
=> y = 0 => x + 0 = 5 => x = 5
=> vertix = (5,0)
3) line x + y = 5 and x = 0
=> 0 + y = 5 => y = 5
=> (0,5) ------> this is not a vertix because it is above the line y = 3
4) line y = 3 and x-axis
=> vertix = (0,3)
5) x-axis and y-axis => origin => vertix = (0,0)
So, there are four vertices: (0,0), (5,0), (2,3) and (0,3)

Answer:
Deon
Step-by-step explanation:
Gerain has 2 parts almonds in 5 parts total, i.e., 2/5 = 0.40
Deon has 3 parts almonds in 7 parts total, i.e., 3/7 ≈ 0.43
So Deon's concentration is higher
