Answer:
(x - 5) (x (4 x - 3) + 8)
Step-by-step explanation:
4 x^3 - 23 x^2 + 23 x - 40
x (x (4 x - 23) + 23) - 40
(x - 5) (x (4 x - 3) + 8)
Answer:
min = -9
max =3
Step-by-step explanation:
C = x-3y
x ≥0
x≤3
y≥0
y≤3
The minimum will be be when x is smallest and y is at its max
x =0 and y = 3
C = 0 - 3(3)
C = 0-9 = -9
The minimum is -9
The maximum occurs when x is largest and y is smallest
x =3 and y = 0
C = 3 - 3(0)
C = 3-0 = 3
The max is 3
