Answer:

r = -9.5

Step-by-step explanation:

1/4 = 1/2(r + 10)

1/4 = 1/2r + 5

-5               -5

1/2r = -4 3/4

1/2 x 2/1 = -4.75 x 2/1 or (2)

r = -9.5

To check work:

1/4 = 1/2(-9.5 + 10)

1/4 = -4.75 +5

1/4 = 1/4

OLEGan [10]

The comparison of shoes placed on the floor by Helena next to each other change from reflection to translation.

<h3>What do you mean by reflection?</h3>

The reflection of a plane or shape is flipping the original figure with respect to a reference line.

The rule of reflection are given below,

  • Reflection about x-axis (x,y)-->(x,-y)
  • Reflection about y-axis (x,y)-->(-x,y)

Before training for the obstacle course, Helena bought a new pair of athletic shoes.  

  • She placed the shoes on the floor next to each other and noticed that the right shoe looked just like a reflection of the left shoe.
  • This is because, the separating line works as the symmetry line between both the shoes.

Now she had accidentally purchased two left shoes. Now, if she puts a left shoe to another left shoe, then it looks like the translated image of the first shoe.

Hence, the comparison of shoes placed on the floor by Helena next to each other change from reflection to translation.

olganol [36]

Answer:

Myrna earned $674 for that week.

Myrna earns 2% commission IF the weekly sales is over $12,500. Since $21,200 is over $12,500. We can imply the 2% commission into Myrna's weekly pay.

Step-by-step explanation:

1) Multiply last weeks sells by .02

$21,200 * .02 = $424

2) Add $424 to Myrna's $250

$424 + $250 = 674
