To find the equation of a perpendicular line, you first need to find the negative reciprocal of the slope given. The slope is -1/3, so the slope of the perpendicular line will be 3
Now we just need to find the y intercept using the point (3, 2) and you can plug the coordinates in and then solve for b. Let's see what that looks like.
y=3x+b
2=3*(3)+b
2=9+b
-7=b  So now we know the y-intercept and slope. We just put them together now
y=3x-7
 
        
                    
             
        
        
        
X - number of months ( 1, 2 or 3 );
A function is:
f ( x ) = 50 x + 200
A reasonable domain is:
x ∈ { 1, 2, 3 }
The range is:
y ∈{ $250, $300, $350 }
        
                    
             
        
        
        
Answer:
x = 2
Step-by-step explanation:
You are solving for the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. 
PEMDAS is the order of operation, and = 
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction. 
First, subtract 25 from both sides of the equation: 
5x + 25 (-25) = 35 (-25)
5x = 35 - 25
5x = 10
Isolate the variable, x. Divide 5 from both sides: 
(5x)/5 = (10)/5
x = 10/5
x = 2
x = 2 is your answer.

Answer:
2/3 can't be divided because it's in its lowest form so you can reduce it 
 
        
                    
             
        
        
        
2 divides both numbers, so divide both numbers by 2 to get 3 and 7. These are relatively prime, so 2 is the gcd. The lcm is 6*14/2=42.
