Write your answer as a decimal rounded to the nearest thousandth.

x = 1.55

y = 1.86

Step-by-step explanation:

Determinant of the original matrices;

Do = -3(4) -9(6)

Do = -12 - 54

Do = -66

For Dx

Replace the answer in the first column and fine the determinant

Dy = 17(-3) - 8(9)

Dy = -51-72

Dy = -123

y = Dy/Do

y = -123/-66

y = 1.86

Get Dx

Dx = 4 (-8) - 17(6)

Dx = -32-102

Dx = -134

x = Dx/Do

x = -132/-66

x = 1.55

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
