2x-3y <= 12

Subtract 2x from both sides:

-3y <= 12 - 2x

Divide all terms by -3 ( when you divide an inequality by a negative value you must also reverse the inequality sign)

y >= -4 +2/3x or can be written as y >=2/3x -4

Answer:

2x - y \leqslant 12 \\  -3 y \leqslant  - 2x  + 12 \\ 3y \geqslant 2x - 12 \\ y \geqslant  \frac{2}{3} x - 4

Which board geometrically represents 4x2 – 1 using algebra tiles? An algebra tile configuration showing only the product spot, w
NemiM [27]

An algebra tile configuration shows only the product spot, which has 9 tiles in 3 columns with 3 rows. First row: 2 + x squared, 1 + x. Second row: 2 + x squared, 1 + x. Third row: 2 negative x, 1 negative.

The correct option is B.

Given

Equation; \rm 4x^2 - 1

<h3>Quadratic equation</h3>

It is a polynomial that is equal to zero.

Polynomial of variable power 2, 1, and 0 terms are there.

Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.

4x² -1 = 0 is a quadratic equation.

An algebra tile configuration showing only the product spot, which has 9 tiles in 3 columns with 3 rows. First row: 2 + x squared, 1 + x. Second row: 2 + x squared, 1 + x. Third row: 2 negative x, 1 negative.

Then,

The factors of the polynomial is;

\rm 4x^2 - 1=0\\\\ 4x^2-2x+2x-1=0\\\\ 2x(2x-1)+1(2x-1)=0\\\\(2x-1)(2x+1)=0

Hence, an algebra tile configuration shows only the product spot, which has 9 tiles in 3 columns with 3 rows. First row: 2 + x squared, 1 + x. Second row: 2 + x squared, 1 + x. Third row: 2 negative x, 1 negative.

More about the quadratic equation link is given below.
