Find the orthogonal trajectories of the family of curvesx- ky2, where k is an arbitrary constant.

15 there is a line that includes the point 0,10 and has a slope of 7/4. what is it’s equation in slope intercept form

If set d is not the empty set but is a subset of set e, then which of the following is true? d ∩ e = d d ∩ e = e d ∩ e = ∅

Will give brainliest b. describe the function over each part of its domain. state whether it is constant, increasing, or decreasing, and state the slope over each part.
