The communicative property means that multiplied numbers can be multiplied in any order.

3*2*4 is the same as 2*4*3. The answer will be the same.

So (24 * x) is the same as (x * 24).

Hope this helps! :)

Which of the following is equivalent to 6x 2 + x - 12 ?

bagirrra123 [75]

$6x^2+x-12=6x^2-9x+8x-12=3x(2x-3)+4(2x-3)\\\\=(2x-3)(3x+4)\\\\other\ method:\\\\6x^2+x-12\\a=6;\ b=1;\ c=-12\\\Delta=b^2-4ac\to\Delta=1^2-4\cdot6\cdot(-12)=1+288=289\\\\x_1=\frac{-b-\sqrt\Delta}{2a};\ x_2=\frac{-b+\sqrt\Delta}{2a}\\\\\sqrt\Delta=\sqrt{289}=17$

$x_1=\frac{-1-17}{2\cdot6}=\frac{-18}{12}=-\frac{3}{2};\ x_2=\frac{-1+17}{2\cdot6}=\frac{16}{12}=\frac{4}{3}\\\\6x^2+x-12=6(x+\frac{3}{2})(x-\frac{4}{3})=2\cdot3(x+\frac{3}{2})(x-\frac{4}{3})\\\\=2(x+\frac{3}{2})\cdot3(x-\frac{4}{3})=(2x+3)(3x-4)$

Answer:

The method used is substitution method

x = 2, y = -6

Step-by-step explanation:

Given the simultaneous equation

Y = −3x ..... 1

4x + y = 2 ... 2

Substitute equation 1 into 2

4x + (-3x) = 2

4x - 3x = 2

x = 2

Get y:

y = -3x

y = -3(2)

y = -6

Hence the value of (x, y) is (2, -6)

Domain is the set of x-values that can be inputted into function f(x)

Step-by-step explanation:

According to the graph, we see that the line's x-values span from negative infinity to infinity. Therefore our domain encapsulates all real numbers.
