Answer:
The sequence of transformations will map figure K onto figure K′
is the first sequence <u>option (1)</u>
======================================================
Step-by-step explanation:
See the attached figure
as shown in the figure the K' is the image of K by reflection over x-axis
<u>But </u> We need to know which sequence of transformations will give the same result.
So, we will test the options by any point from K and its image from K'
i.e: we will test the options using the points (6,5) , (6,-5)
(6,5) ⇒ (6,-5)
<u>option (1):</u>
Reflection across x = 4, 180° rotation about the origin, and a translation of (x + 8, y)
(6,5) ⇒ (2,5) ⇒(-2,-5) ⇒ (6,-5)
<u>option (2):</u>
Reflection across x = 4, 180° rotation about the origin, and a translation of (x − 8, y)
(6,5) ⇒ (2,5) ⇒(-2,-5) ⇒ (-10,-5)
<u>option (3):</u>
Reflection across y = 4, 180° rotation about the origin, and a translation of (x + 8, y)
(6,5) ⇒ (6,3) ⇒ (-6,-3) ⇒ (2,-3)
<u>option (4):</u>
Reflection across y = 4, 180° rotation about the origin, and a translation of (x − 8, y)
(6,5) ⇒ (6,3) ⇒ (-6,-3) ⇒ (-14,-3)
As shown: The sequence of transformations will map figure K onto figure K′
is the first sequence <u>option (1)</u>
<em>Question Continuation:</em>
<em>Glenn bought 3 pounds of tomatoes. He used 5/8 of them to make sauce. </em>
<em>Make an equation that shows the number of pounds of tomatoes Glenn used for the sauce.</em>
<em></em>
Answer:
Step-by-step explanation:
Given
Weight of Tomato = 3 lb
Used Proportion = 5/8
Required
Determine the portion used
To solve this we simply multiply the used proportion by the weight of the tomato bought
Represent the used portion with y.
So:
