There are three kinds of rock: igneous, sedimentary, and metamorphic.
Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers. Metamorphic rocks result when existing rocks are changed by heat, pressure, or reactive fluids, such as hot, mineral-laden water. Most rocks are made of minerals containing silicon and oxygen, the most abundant elements in the Earth’s crust.
Answer:
h(x) = 2x² -8x -10
Step-by-step explanation:
In the US, a quadratic is in standard form when the terms are listed in order of decreasing degree.
In the UK, a quadratic is in standard form when it is written in vertex form.
__
<h3>US</h3>
The only function with terms in order of decreasing degree is ...
h(x) = 2x² -8x -10
<h3>UK</h3>
All of the functions <em>except the last</em> are written in vertex form:
- f(x) = (x +1)² +0 . . . . . . . . would usually be written f(x) = (x +1)²
- y(x) = -(x -6)² +16
- g(x) = -3(x -3)² +4
__
<em>Additional comment</em>
Since the question asks about <em>one</em> function, we assume it is from the perspective of the US understanding of <em>standard form</em>. The point here is that "standard form" may vary from one tradition to another. (The "standard form" for numerical values varies by tradition, as well.)
Answer:
2x - 3
Step-by-step explanation:
The Distributive Property of Multiplication applies here. Multiply each of the two terms inside parentheses by-1/4: 2x - 3
X=12 because I said so and I’m smart
