True — provided there is no horizontal force (i.e., neglecting air resistance). For projectile motion with only gravity, ax = 0 so the horizontal component of velocity is constant:

vx(t) = vx0 = v0 cosθ.

If air resistance or another horizontal force acts, the horizontal velocity will change and the statement is not true.
