Multiply everything in the parenthesis by -4.

-12 + 8x + 2x = 2x - 8

Combine like terms.

-12 + 10x = 2x - 8

Subtract 10x from both sides.

-12 = -8x - 8

Add 8 to both sides.

-4 = -8x

Divide both sides by -8.

x = 0.5

Hope this helps!

A parabolic archway is 12 meters high at the vertex. at a height of 10 meters, the width of the archway is 8 meters. how wide is
Virty [35]
To solve this problem you must apply the proccedure shown below:

 1. You have that the <span>parabola is 12 meters high at the vertex and at a height of 10 meters, the width is 8 meter. 

 2. Therefore, you have:

 x^2=-4a(y^2-k)
 4</span>^2=-4a(10-12)
 16=-40a+48
 16=8a
 a=16/8
 a=2

 y=0
 x^2=-8(0-12)
 x^2=96
 x=√96
 x=9.79x2
 x=19.58

 3. Therefore, as you can see, the answer is: 19.58 meters.<span>

Will Mark brainliest if correct.
Serhud [2]

Answer:

SF = 7/3

Step-by-step explanation:

Like the problem hint says, you want to put the new coordinate over the old one to find the scale factor. We'll use both x and y.

-7/-3 = 7/3

14/6 = 7/3

Therefore, the scale factor is 7/3.

Talja [164]

Answer:

Step-by-step explanation:

The question got caught off. Can't read any of the other examples. I can tell you though that ice melting is a physical change, not a chemical change.
