For each equation, decide if it is always true or never true. x - 13 = x + 1

x - 3 = 2x - 3 - x

2(x + 3) = 5x + 6 - 3x

3(x - 5) = 2(x - 5) + x

(if f(x)=4x^2 and g(x)=x+1, find (f o g)(x)

Point a is located at (0, 4), and point c is located at (−3, 5). find the x value for the point b that is located one fourth the distance from point a to point c. −0.25 −0.5 −0.75 −1
