Answer:

(1,3)

Step-by-step explanation:

Rotating clockwise means that you're rotating by a negative angle measure. The rule for rotating -90 degrees is (x,y)->(y,-x). X is (-3,1) so X' should be (1,3) since you negate -3 to get 3 and switch the x and y coordinates.

A boy bought an article for £9. He spent £4

Marina86 [1]

Answer:

Profit % = 39%

Step-by-step explanation:

Cost price of the article = 9

Price for repairing = 4

Therefore, Total cost of the article = 9 + 4 = 13

Selling price of the article = 18

Profit = 18 - 13 = 5

Hence,

$Profit \% = \frac{Profit}{Cost \ price} \times 100\\\\$

$= \frac{5}{13} \times 100\\\\=38.46 \%\\\\=38.5 \%$

Profit percent (to the nearest %) = 39%
