Use the chain rule to find dz/dt. z = xy9 − x2y, x = t2 + 1, y = t2 − 1

The value of dz/dt using the chain rule is

According to chain rule:

Given the following expressions

z = xy⁹ − x²y,

x = t² + 1

y = t² − 1

Get the differentials in the equation

Substitute the differentials into the formula

Hence the value of dz/dt using the chain rule is

the correct answer is 45x

9×5=45 then add the x

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17
