Answer:
(-7, -3)
Step-by-step explanation:
So the formula is (x, y) --> (-y, x) for a 90 degrees counterclockwise rotation.
To apply this formula to (-3,7), first identify which is the x-coordinate and which is the y-coordinate.
x-coordinate is -3 & y-coordinate is 7
Then you literally just substitute it into the formula like so:
(-y, x) -->(-(7), (-3)) --> (-7, -3)
Try to put parantheses around the coordinate when substituting to prevent confusion & incorrect negative signs.

X= number of belts
multiply $14.76 times number of belts sold, add $50 and set this equal to $475.00.
$14.76x + $50= $475.00
subtract 50 from both sides
14.76x= 425.00
divide both sides by 14.76
x= 28.794 belts
* since we cannot sell partial belts, round up to the next whole number
ANSWER: The store must sell a minimum of 29 belts.
Hope this helps! :)
Answer:
6cm
Step-by-step explanation:
Area of the trapezoid = Area of the square + Area of the triangle
Area of the square= Area of the trapezoid - Area of the triangle
Area of the square= 60 - 24
Area of the square= = 36 square metres
Since Area of the square= L²
L is the length of the side of the square
L² = 36
L = √36
L = 6cm
Hence the required length is 6cm
well if
120-74=46
then 46 is the correct answer.
74+46= 120
