<h3>A. Therefore the percentage of decrease he drove this week compared to the last week is 25%</h3><h3>B.Therefore at store A will the cost of blanket be less this week</h3>
Step-by-step explanation:
A.
Christopher drove 360 miles this week . Last week he drove 480 miles .
He drove = (480 -360 ) miles = 120 miles less than this week .
Therefore the percentage of decrease he drove this week compared to the last week is= % =25%.
B.
At store A , a blanket usually costs $50 and blanket the same at store B usually cost$62. This week , the blanket is on sale At store A for 20% off and at store B for 30% off.
At store A ,
This week, the cost of the blanket is = $ = $
= $40
At store B
This week, the cost of the blanket is =$ =$
= $ 43.4
Therefore at store A will the cost of blanket be less this week

The reflection of BC over I is shown below.
<h3>What is reflection?</h3>- A reflection is a mapping from a Euclidean space to itself that is an isometry with a hyperplane as a set of fixed points; this set is known as the reflection's axis (in dimension 2) or plane (in dimension 3).
- A figure's mirror image in the axis or plane of reflection is its image by reflection.
See the attached figure for a better explanation:
1. By the unique line postulate, you can draw only one line segment: BC
- Since only one line can be drawn between two distinct points.
2. Using the definition of reflection, reflect BC over l.
- To find the line segment which reflects BC over l, we will use the definition of reflection.
3. By the definition of reflection, C is the image of itself and A is the image of B.
- Definition of reflection says the figure about a line is transformed to form the mirror image.
- Now, the CD is the perpendicular bisector of AB so A and B are equidistant from D forming a mirror image of each other.
4. Since reflections preserve length, AC = BC
- In Reflection the figure is transformed to form a mirror image.
- Hence the length will be preserved in case of reflection.
Therefore, the reflection of BC over I is shown.

The question you are looking for is here:
C is a point on the perpendicular bisector, l, of AB. Prove: AC = BC Use the drop-down menus to complete the proof. By the unique line postulate, you can draw only one segment, Using the definition of, reflect BC over l. By the definition of reflection, C is the image of itself and is the image of B. Since reflections preserve , AC = BC.
here is the answer its in the picture and it also has the solution in picture 2
