Complete the table for the given rule. Rule: y=X/4(fraction)

Lady_Fox [76]

Answer:

$\large\huge\boxed{\begin{array}{c|c}x&y\\\\4&1\\\\2&\frac{1}{2}\\\\9&\frac{9}{2}\end{array}}$

Step-by-step explanation:

$y=\dfrac{x}{4}$

Put the values of x from the table to the equation:

$x=4\to y=\dfrac{4}{4}=1\\\\x=2\to y=\dfrac{2}{4}=\dfrac{2:2}{4:2}=\dfrac{1}{2}\\\\x=9\to y=\dfrac{9}{4}$

From the comment.

Convert the equation:

$y=\dfrac{x}{4}$ <em>multiply both sides by 4</em>

$4y=x\to x=4y$

Put the values of y from the table to the equation:

$y=4\to x=(4)(4)=16\\\\y=2\to x=(4)(2)=8\\\\y=9\to x=(4)(9)=36$

$\large\huge\boxed{\begin{array}{c|c}x&y\\\\16&4\\\\8&2\\\\36&9\end{array}}$

If y= -3x7+2x3+ x, the derivative of y with respect to x is

larisa [96]

Answer:

$\frac{dy}{dx}$ = - 21 $x^{6}$ + 6x² + 1

Step-by-step explanation:

Differentiate each term using the power rule

$\frac{d}{dx}$ (a $x^{n}$ ) = na $x^{n-1}$

Given

y = - 3 $x^{7}$ + 2x³ + x , then

$\frac{dy}{dx}$ = (7 × - 3 ) $x^{6}$ + (3 × 2)x² + (1 × 1 ) $x^{0}$

= - 21 $x^{6}$ + 6x² + 1
