A because 1×2 is 2 than 2×2 is 4
Answer:
It's the left graph, y = f(x)
Step-by-step explanation:
If you find the x-intercepts, you'd solve (2-3x)/x = 0. This means you'd really solve 2-3x=0, which gives you x=3/2.
So the graph must have an x-intercept at (1.5, 0). Only f(x) has that.
Answer:
Step-by-step explanation:
If angle C is the right angle, then side c is the hypotenuse.
Use Pythagoras' Theorem 
to find the length of side a:
Given:
<u>Tan Trig Ratio</u>
where:
is the angle- O is the side opposite the angle
- A is the side adjacent the angle
Given:
- = A
- O = side opposite angle A = a = 9
- A = side adjacent angle A = b = 2√22
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.
