Triangle JKL is transformed using the rule . Point K of the pre-image is at (4, 7). What are the coordinates of point K" on the

Zanzabum

Answer:

Option C.

Step-by-step explanation:

Consider the complete question is "Triangle JKL is transformed using the rule $R(O,90^\circ)\circ r_{y=-x}(x,y)$ . Point K of the pre-image is at (4, 7). What are the coordinates of point K'' on the final image?".

According to $r_{y=-x}(x,y)$ , we get

$(x,y)\rightarrow (-y,-x)$

According to $R(O,90^\circ)$ , we get

$(x,y)\rightarrow (-y,x)$

The rule $R(O,90^\circ)\circ r_{y=-x}(x,y)$ means first reflection and then rotation.

We need to find the image of K(4,7).

After reflection, we get

$K(4,7)\rightarrow K'(-7,-4)$

After rotation, we get

$K'(-7,-4)\rightarrow K''(4,-7)$

Therefore, the correct option is C.

Find the product. (–5k + 5)(–5k2 + 2k – 8)

boyakko [2]

Answer:

25 K³ - 35k²+ 50 K - 40

===========================================

Step-by-step explanation:

Given that :

(-5k + 5)(-5k² + 2k - 8)

= -5K (-5k² + 2k - 8) + 5 (-5k² + 2k - 8)

= 25 K³ - 10k² + 40 K - 25 K² + 10 K - 40

= 25 K³ - 35k²+ 50 K - 40

<u>So, the product = 25 K³ - 35k²+ 50 K - 40</u>
