Describe the rule for the rotation.

finlep [7]

Answer:

Step-by-step explanation:

If you draw a line from the origin (0,0) to L ( the original point ) and a different line from the origin to the image L' you can see the angle of rotation as being

90 degrees and that the rotation is clockwise.

the rule is (x, y) become ( y, -x)

Find the slope of the line through each pair of points (6, -10) , (-15 , 15)

dem82 [27]

<h3>Answer:</h3>

$\boxed{\boxed{\pink{\bf \leadsto The \ slope \ of \ the \ line \ is \ \dfrac{-25}{21}.}}}$

<h3>Step-by-step explanation:</h3>

Two points are given to us and we need to find the slope of the line . The slope of the line passing through points $\bf (x_1,y_1 ) \ \& \ (x_2,y_2)$ is given by ,

$\qquad\boxed{\red{\bf Slope = tan\theta=\dfrac{y_2-y_1}{x_2-x_1}}}$

Here , the points are ,

( 6 , -10 )
( -15 , 15 )

$\bf\implies Slope = \dfrac{y_2-y_1}{x_2-x_1} \\\\\bf\implies Slope =\dfrac{15-(-10)}{-15-6} \\\\\bf\implies Slope = \dfrac{15+10}{-21}\\\\\bf\implies Slope =\dfrac{-1(25)}{-1(-21)}\\\\ \bf\implies\boxed{\red{\bf Slope =\dfrac{-25}{21}}}$

<h3>★ Hence the slope of the line joining the two points is -25/21 .</h3>

Write the equation in slope-intercept form: 4x -2y =12

DedPeter [7]

$4x - 2y = 12 \\ \: \: \: \: \: \: \frac{ - 2y}{ - 2} = \frac{ - 4x}{ - 2} \: + \frac{12}{ - 2} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: y = 2x - 6$

Therefore, the answer is 1) y = 2x - 6

One serving of oatmeal provides 16% of the fiber you need daily. You must get the remaining 21 grams of fiber from other sources

Marta_Voda [28]

You should consume 25 grams of fiber daily.

The oatmeal represents 16% of the fiber.
The rest of the fiber (21 grams) is 84%.

If 21 grams = 84%, then 1 gram = 4%.
If 1 gram = 4%, then 25 grams = 100%.
