g(2x) is $g(2x)=12x^2-6$

Step-by-step explanation:

We are given $g(x)=3x^2-6$

We need to find g(2x)

Solving:

$g(x)=3x^2-6\\g(2x)=3(2x)^2-6\\g(2x)=3(4x^2)-6\\g(2x)=12x^2-6$

So, g(2x) is $g(2x)=12x^2-6$

Which equations are equivalent to Y=2/3X-4 when written in slope-intercept form? Check all that apply. A =3X-2Y=4. B=2X-3Y=12. C

shusha [124]

The slope-intercept form: y = mx + b.

The standard form: Ax + By = C.

We have:

$y=\dfrac{2}{3}x-4$ multiply both sides by 3

$3y=2x-12$ subtract 2x from both sides

$-2x+3y=-12$ change the signs

$2x-3y=12\to\boxed{B.}$ multiply both sides by (-4)

$-4(2x-3y)=-4(12)\to\boxed{C.}$

<h3>Answer: B and C.</h3>

A. 3x - 2y = 4 - NOT

D. 2(x + 6) = 3y → 2x + 12 = 3y → 2x - 3y = -12 - NOT

E. 2x - 3y = 4 - NOT
