Answer:

x = 4/5

Step-by-step explanation:

3(x-4)=12x

3x-12=12x

3x+12x-12=12x-12x

15x-12=0

15x-12+12=0+12

15x=12

15x/15=12/15

x = 4/5

hope it's helpful ❤❤❤❤

THANK YOU.

Find the equation of a parabola with a vertical axis and its vertex at the origin and passing through the point (-2, 3).
jonny [76]

Answer:

y=\frac{3}{4}x^2

Step-by-step explanation:

Hi there!

Because we're given the vertex of the parabola, we can determine its equation in vertex form:

y=a(x-h)^2+k where the vertex is (h,k)

Plug in the vertex (0,0)

y=a(x-0)^2+0\\y=a(x)^2\\y=a(x-0)^2+0\\y=ax^2

Now, we must solve for a. Plug in the given point (-2,3) and solve for a:

3=a(-2)^2\\3=4a\\\frac{3}{4} =a

Therefore, the value of a is \frac{3}{4}. Plug this back into y=ax^2:

y=\frac{3}{4}x^2

I hope this helps!

Change the equation to slope intercept form and identity the slope and y-intercept -8x+2y=6
gulaghasi [49]

The answer is:

y=4x+3

The slope is: 4

The y-intercept is: 3

The explanation is shown below:

1. The slope intercept form of the linear equation is:

y=mx+b

Where m is the slope and b is the y-intercept.

2. Therefore, you must solve for <em>y</em>, as following:

-8x+2y=6\\y=\frac{8x+6}{2}\\y=4x+3

m=4\\b=3
