x+10      x ≠ 60
Step-by-step explanation:
 (x^2−50x−600)
----------------------
    (x−60) 
Factor the numerator
(x-60)(x+10)
-------------------
(x-60)
Cancel the like terms

Answer:
y= 3x
Step-by-step explanation:
The slope is just read. It is 3. It is the value of m in the general equation.
y = mx + b
y = 3x + b
To find b, use (-1,-3)
x = -1
y = -3                  Substitute into the general equation
-3 = 3(-1) + b       Simplify the right side
-3 = -3 + b          Subtract -3 from both sides 
b = 0
Answer: y = 3x
 
        
             
        
        
        
Answer:
a=3
Step-by-step explanation:
The formula for direct proportion is 
f = ka
Let f= 42 and a = 7
42 = k*7
Divide each side by 7
42/7 = k7/7
6 =k
f = 6a
Let f = 18
18 = 6a
Divide each side by 6
18/6 = 6a/6
3 =a
