Y=(3x+7)(8x-5). Find the derivative

lozanna [386]

Answer:

Step-by-step explanation:

use uv rule= uv'+vu'

u=3x+7

u'=3+0=3

v=8x-5

v'=8-0=8

uv= (3x+7)(8)+(8x-5)(3)

=24x+56+24x-15

=48x+41

Debora [2.8K]

Step-by-step explanation:

the second answer.

they are parallel and congruent (same length).

simply because both points were translated by adding the same number of units to x. so, they have the same length, and point in the same direction.

Find the values of x and y.

olchik [2.2K]

Answer:

value of x = 26

value of y = 26 \|2

( 26 root 2 )

Step-by-step explanation:

here's the solution : -

=》

$\sin(45) = \frac{perpendicular}{hypotenuse}$

=》

$\frac{1}{ \sqrt{2} } = \frac{26}{y}$

=》

$y = 26 \sqrt{2}$

and

$\tan(45) = \frac{perpendicular}{base}$

=》

$1 = \frac{26}{x}$

=》

$x = 26$

Eleven more than four times a number equal the number less 7 find the number

bixtya [17]

For this case we have to:

x: Let the variable representing the unknown number

We algebraically rewrite the given expression:

Eleven more than four times a number, is represented as:

$11 + 4x$

The number less 7, is represented as:

$x-7$

Thus, the complete expression is:

$11 + 4x = x-7$

We subtract x from both sides of the equation:

$11 + 4x-x = -7\\11 + 3x = -7$

We subtract 11 from both sides of the equation:

$3x = -7-11$

Equal signs are added and the same sign is placed:

$3x = -18$

We divide by 3 on both sides of the equation:

$x = - \frac {18} {3}\\x = -6$

Answer:

$x = -6$
