Both x and y denote functions of t that are related by the given equation. Use this equation and the given derivative information to find the specified derivative. Equation: x+7y=7

(a)Given that dx/dt=5, find dy/dt when x=6.

(b)Given that dy/dt=10, find dx/dt when x=7.

What’s the domain of this function? fastttt

What is the value of x in the this question ?

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.
