when you solve a system of equations by the substitution method, how do you determine whether the system of equations is dependent?
Well, we know x=3 and y=8 and dx/dt=4. We need to find z (the distance from the particle to the origin) dy/dt, and finally our answer dz/dt. First solve for dy/dt y=2(3x+7)^(1/2) dy/dt=[2(1/2)(3x+7)^(-1/2)](3dx/dt) dy/dt=[(3x+7)^(-1/2)]3dx/dt dy/dt=[(3(3)+7)^(-1/2)](3(4)) dy/...
