Which shows the image of ΔRST after the rotation (x, y) → (y, –x)? On a coordinate plane, a triangle has points R (negative 2, 1

), S (1, 3), T (negative 1, 8). On a coordinate plane, a triangle has points R prime (1, 2), S prime (3, negative 1), T prime (7, 1). On a coordinate plane, a triangle has points R prime (1, negative 2), S prime (3, 1), T prime (7, negative 1). On a coordinate plane, a triangle has points R prime (negative 1, negative 2), S prime (negative 3, 1), T prime (negative 7, negative 1).

Answer:

  On a coordinate plane, a triangle has points R prime (1, 2), S prime (3, negative 1), T prime (7, 1)

Step-by-step explanation:

We assume that the coordinates of the vertices of the given triangle are supposed to be ...

  R(-2, 1), S(1, 3), T(-1, 7)

Then the given transformation (x, y) ⇒ (y, -x) will transform these to ...

  R'(1, 2), S'(3, -1), T'(7, 1) . . . . . (matches the first choice)

A furniture store pays a wholesale price for a mattress. Then, the store marks up the retail price to 150% of the wholesale pric
slega [8]
Part A:

Given that <span>the mattress is sold for 50% off of the retail price, let the retail price of the mattress be x, then

50% of x = 1200
⇒ 0.5x = 1200
⇒ x = 1200 / 0.5 = 2400

Therefore, </span><span>the retail price of the mattress, before the discount is $2,400.



Part B:

Given that </span><span>the store marks up the retail price to 150% of the wholesale price. Let the whole sale price be p, then

(100% + 150%) of p = 2400
250% of p = 2400
2.5p = 2400
p = 2400 / 2.5 = 960.

Therefore, </span><span>the wholesale price, before the markup was $960</span>
