hello :
at the point where a=2 y = 4(2)-5 =3 (commun the curve and the tangent)
so :f(2) = 3
f'(2) =4 (slope of the tangent )
If the expression is 2*x*3, x must be 1/3 in order to cancel out the 3 which would leave the 2.
Consider this option:
11) 360-(95+32)=233; answer D;
14) if 2x+2=x+11, then x=9, and y-2=9+2, y=13; answer A.
