Answer:
- reflection over y = 2.5
- translation left 1
Step-by-step explanation:
The orientation of the triangle is reversed, so a reflection is required. Horizontal lines remain horizontal, but up/down are reversed, so the reflection is across a horizontal line. The horizontal line that is halfway between each point and its image is the line y = 2.5.
The x-coordinates of the image points are 1 less than the x-coordinates of the original, so a left shift of 1 unit is involved.
The two transformations to get from A to B could be (in any order) ...
- reflection over the line y = 2.5
- translation left 1 unit
__
The transformation can be summarized by ...
(x, y) ⇒ (x -1, 5 -y)
Answer:
50 products.
Step-by-step explanation:
He wants to gain 5000 - 500 = $4500 from his sales.
He has to sell 4500 / 90 = 50 products.

Answer:
n = 150
Step-by-step explanation:
If n is the number of T-shirt sell each month, then the revenue function of Sophia's store is r = 21n .......... (1)
and the cost function of her store is C = 16n + 750 ........ (2)
Now, at break-even point, the revenue of a business is equal to its cost.
Therefore, r = C
{From equations (1) and (2)}
⇒ 21n = 16n + 750
⇒ 5n = 750
⇒ n = 150
So, the break-even point of the store will occur when the number of T-shirt production is 150. (Answer)
