Let f(x)= 3x - 1 and g(x)=x^2 + 1 Find (f o g) 7).
Then (fog)(7) = 1. (Simplify your answer.)

Step-by-step explanation:

I do not fully understand your question yet

assuming this is what you asked

f(x) = 3x-1 and g(x) = x² +1  

f o g(7)  = f( g(7)) = f( 7² +1) = f( 50) = 3*50 -1 = 149

(f o g) (7) = f(g(x))(7) = f( x²+1)(7) = ( 3x²+3-1) (7) = (3x²+2)(7) ...

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:
