Answer:
A relation has an input value which corresponds to an output value. When each input value has one and only one output value, that relation is a function. Functions can be written as ordered pairs, tables, or graphs. The set of input values is called the domain, and the set of output values is called the range.

Answer:
C
Step-by-step explanation:
The x's can not completely cancel each other out so they are still included but you have to divide the numbers, exponents and whole numbers.
Answer:
C
Step-by-step explanation:
16 : 12
x : 6
- multiply 16*6 and divide by the number multiplying with the unknown (12)
(16*6)/12 = 8
- area of triangle is 1/2 h*b
so 1/2 * (16*8) = 64
C
By subtracting 18 to both sides you are separating the 3x because you are not ready to isolate the variable (x) in step 1
