Answer:
This is an equation for a parabola. All parabolas are functions.
answer: function
Step-by-step explanation:
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.
Answer: OPTION A
Step-by-step explanation:
We need to remember that Product of powers property, which states that:

Let's check the options:
A. For
you can apply the property mentioned before. Then:

(It is the equivalent expression)
B. Add the exponents:

(It is not the equivalent expression)
C. For
you can apply the property mentioned before. Then:

(It is not the equivalent expression)
D. We know that
and we maje the addition indicated in this option, we get:

(It is not the equivalent expression)
The value of x can be found using the sine function.
sin 30 = x/8
8 (sin 30) = x
4 = x
-4x-24=8
So you move the -24 to the other side.
-4x=32
Divide both sides by -4.
x=-8
