If 2 + 3i is a zero, then 2 - 3i is also a zero

x(x - 2 - 3i)(x - 2 + 3i)
= x(x² - 2x  + 3ix - 2x + 4 - 6i - 3ix + 6i - 9i²
= x(x² - 4x + 4 + 9)
= x(x² - 4x + 13)
= x³ - 4x² + 13x

Alja [10]

Answer:

The inequalities that must be satisfied is

x + y  \leq  32

x(800) + y(250)  \leq 3500

Step-by-step explanation:

Let the number of  Heineken bottles be x

Let the number of  monster drink bottles be y

Her crate cannot hold more than 32, This situation can be represented as

\text{Number of  Heineken bottles  +   number of  monster drink bottles } \leq 32

That is

x + y  \leq  32 ------------------------(1)

Cost of one Heineken bottles = $800

Cost of one  monster drink bottles = $250

then

x \times \text{cost of one Heineken bottle }  + y \times \text{ cost of one monster drink bottle} \leq 3500x

x(800) + y(250)  \leq 3500------------------(2)

dimaraw [331]
-3x+7y=5 (x2) -> -6x+14y=10

-6x+14y=10
-8x+14y=-10

2x=20
x=20/20
x=1

Susbstitute x=1,

-8x+14y=-10
-8(1)+14y=-10
-8+14y=-10
14y=-10+8
14y=-2
y=-2/14
y=-1/7
