Solve for x:
x + 5 = -3x + 25

The table below shows the height of a ball  x  seconds after being kicked.  what values, rounded to the nearest whole number, complete the quadratic regression equation that models the data? f(x)  =  x2  +  x  +  0based on the regression equation and rounded to the nearest whole number, what is the estimated height after 0.25 seconds?   feet

If f(x) =3x-2 and g(x) =2x+1 fins (f+ g) (x)

If f(x) = x+8 and g(x) = 4x- 3, find (f+g)(x)
