y=5-2x
y'(u-v)=du/dx-dv/dx
y'(5-2x)=d/dx(5)-d/dx(2x)
-The derivative of 5 is 0 because it's a constant.
-The derivative of 2x is:
d/dx(cu)=c*du/dx where c is a constant.
d/dx(2x)=2*d/dx(x)
y'(5-2x)=(0)-[2*d/dx(x)]
-The derivative of x is:
d/dx(xn)=nxn-1
d/dx(x)=1*x1-1
d/dx(x)=1*x0
d/dx(x)=1*(1)
d/dx(x)=1
y'(5-2x)=-[2*(1)]
y'(5-2x)=-(2)
y'(5-2x)= -2

How do you find the derivative of y equals sin8x?
Derivative of sin x = cos x, so chain rule to derive 8x = 8 , answer is 8cos8x
Why was the calculus student confused about y equals ex and the derivative of y equals ex?
Because the derivative of e^x is e^x (the original function back again). This is the only function that has this behavior.

Find the derivative of y equals 3cosx?
y=3 cos(x) y' = -3 sin(x)
Find the derivative y equals sq rt 7 plus 99 plus pie?
y is a sum of constants and so is itself a constant. Its derivative is, therefore, zero.
How do you find the derivative of y equals sin8x?
Derivative of sin x = cos x, so chain rule to derive 8x = 8 , answer is 8cos8x
What is the value for x in the following systems of equations x-y equals 5 2x plus y equals 7?
x - y = 52x + y = 7 (use the substitution method)y = x - 52x + y = 7 (substitute x - 5 for y into the second equation)2x + y = 72x + x - 5 = 73x = 12x = 4Thus x = 4 satisfies both the equations of the system.
What is the derivative of 40xy where x equals 2 and y equals 2?
- the derivative with respect to x is 40y - The derivative with respect to Y is 40xSo, since both x and y equal 2, both derivatives yield 40*2 = 80
What is Y double-prime plus y equals 0?
y"+y'=0 is a differential equation and mean the first derivative plus the second derivative =0.Look at e-x the first derivative is -e-xThe second derivative will be e-xThe sum will be 0
