Answer:
A function is a relationship between two variables, such that one variable is determined by the other variable.
A function can be represented verbally. For example, the circumference of a square is four times one of its sides.
A function can be represented algebraically. For example, 3x+6 3 x + 6 .
A function can be represented numerically.
A function can be represented graphically.

Answer: 125 000
Step-by-step explanation:
50^3 is equal to 50 * 50 * 50
or 50 times itself 3 times
which equals 50 * 50 * 50 = 125000
 
        
                    
             
        
        
        
Answer:
x=30
y=17
Step-by-step explanation:
We know that 6x+9 = 129  since they are vertical angles
6x+9 = 129
Subtract 9 from each side
6x+9 -9 =129-9
6x = 120
Divide by 6
6x/6 =120/6
x = 20
3y+129 =180  since they make a straight line and straight line are equal to 180 degrees
3y+129 =180
Subtract 129 from each side 
3y+129-129=180-129
3y = 51
Divide by 3
3y/3 = 51/3
y = 17
