23. not equivalent because the first row 3x-9y=5 then if you multiplied this equation by 2 it will be 2(3x-9y) = 2(5) so 6x-18y= 10 not 6x-9y=10

24.equivalent because the second row 2y-6x=8 multiplied by 2 is 2(2y-6x)= 2(8) so 4y-12x=16

25. equivalent because the first row 5x+3y=19 multiplied by 2 is 2(5x+3y) = 2(19) SO 10X+6Y=38 and the second row 2x+4y=20 multiplied by 5 is 5(2x+4y)= 5(20) so 10x+20y=100

What is limit of (x cubed 3 x squared 4 x minus 12) as x approaches negative 3? –78 –24 30 54

Sergio039 [100]

The limit of the expression as x approaches -3 is -24

<h3>How to determine the limit of the expression?</h3>

The expression is given as:

$x^3 + 3x^2 + 4x - 12$

As x approaches -3.

The limit expression becomes

$\lim_{x \to -3} x^3 + 3x^2 + 4x - 12$

Substitute -3 for x in the expression

$\lim_{x \to -3} (-3)^3 + 3(-3)^2 - 4*3 - 12$

Evaluate the expression

$\lim_{x \to -3} -24$

Hence, the limit of the expression as x approaches -3 is -24
