Identify the slope of the equation, substitute by distribution I think, substitution for given point coordinates the y-intercept and combined like terms. And rewrite the equation in y-intersect form. I think this is write, have a great day!
        
             
        
        
        
Answer:
B
Step-by-step explanation:
A. (1.5)2 = 3 which is rational.
B. Root of 41 cannot be expressed as a fraction of p/q, where p and q are integers and q not equal to 0.
C. Root of 49 = 7 which is rational.
D. 15(2) = 30 which is rational
 
        
             
        
        
        
F(x)=x^2+2x+1 & g(x)=3(x+1)^2 
now, f(x)+g(x) 
=x^2+2x+1+3(x+1)^2 
=x^2+2x+1+3(x^2+2x+1) 
=x^2+2x+1+3x^2+6x+3 
=4x^2+8x+4<===answer(c) 
next: 
f(x)=x^2-1 & g(x)=x+3 
now, f(g(x))=(x+3)^ -1 
=x^2+6x+9-1 
=x^2+6x+8<====answer(b) 
i solve two of ur problems. 
now try the 3rd one that is similar to no. 1 
and try the last two urself.
        
             
        
        
        
-2x + 5 = 1/3x - 22
-7/3x = -27
-7x = -81
x = 81/7 or 11.57
They will intersect when x = 81/7 or 11.57
        
             
        
        
        
The factored expression would look like this : 3(x+8)(x-8)
