A straight has slope equals to 12 and y-intercept equals to -5. What's the equation for this straight line?

Rama09 [41]

Answer:

$\large{ \tt{❃ \: EXPLANATION}} :$

We're provided : Slope of straight line ( m ) = 12 & y - intercept ( c ) = - 5 and We're asked to find out the equation for this straight line.

You'll have to know : Equation of straight line in slope intercept form : y = mx + c where m is the slope & c is the y-intercept.

$\large{ \tt{❁ \: LET'S \: START}} :$

Using Slope - intercept form of equation of straight line :

$\boxed{ \large{ \tt{❈ \: y = mx + c}}}$

- Plug the values :

$\large{ \tt{↬y = 12x + ( - 5)}}$

$\large{ \tt{↬ \: y = 12x - 5}}$

$↬\large{\tt{12x - 5 = y}}$

$↬ \large{ \boxed{ \bold{ \tt{12x - y - 5 = 0}}}}$

Hence , 12x - y - 5 = 0 is the required equation.

Dy/dxif y = 4x3 + 3x2 + 2

DIA [1.3K]

The function is

$\displaystyle{ y=4x^3+3x^2+2$ .

We recall that the derivative of each monomial $ax^b$ is $a\cdot b\cdot x^{b-1}$ , and the derivative of a constant (function) is 0.

According to this:

$\frac{d}{dx}(4x^3+3x^2+2)=4\cdot 3\cdot x^2 + 3\cdot 2\cdot x+0 =12x^2+6x$ .

Answer: $12x^2+6x$
