Evaluate dydx at x=2 for the function below.<br><br> y=6u^3+5u+2, where u=−3x^2−4x+9

bekas [8.4K]

Step-by-step explanation:

$y = 6u {}^{3} + 5u + 2$

$y = 6( - 3 {x}^{2} - 4x + 9) {}^{3} + 5( - 3 {x}^{2} - 4x + 9) + 2$

Use the chain rule.

$\frac{dy}{dx} = 6(3)( - 3 {x}^{2} - 4x + 9) {}^{2} ( - 6x - 4) + 5( - 6x - 4)$

$18( - 3 {x}^{2} - 4x + 9) {}^{2} ( - 6x - 4) + 5( - 6x - 4)$

Factor out -6x-4,

$( - 6x - 4)(18( - 3 {x}^{2} - 4x + 9) {}^{2} + 5)$

Know plug in x=-2 to evaluate the derivative

$( - 6(2) - 4)(18( - 3(2) {}^{2} - 4(2) + 9) {}^{2} + 5)$

$( - 16)(18(( - 12) - 8 + 9)) {}^{2} + 5)$

$- 16(18( - 11) {}^{2} + 5)$

$- 16(2183)$

$- 34928$

Solve the inequality 2(x-6)<1/2 (12x-8) neeed help

Rudiy27

Hi there...

2( x - 6) < 1/2(12x - 8)
2x - 12 < (12x- 8)/2
2x - 12 < 6x - 4
2x - 6x < -4 + 12
-4x < 8
Divide both sides by -4
-4x/-4 < 8/-4
x > - 2

How can you determine if you divided the numbers correctly

Fittoniya [83]

Multiply them back into each other... You would multiply your answer with the number you divided by (the number ouside the table if you used the table... ) and you should get the larger number you divided.
