Answer : 7 or 7/1
step by step explanation:
Answer:
Because 20 has to be doubled to become 40. While 40 is twice as much as 20 so you just divide 40 by 20 to get 50%.
Explanation:
20 x 20 = 40 = 100%
40 / 20 = 50%
Answer:
The coordinates of point Q' are: Q'(-3, 5)
Step-by-step explanation:
When a point P(x, y) is rotated 90° counterclockwise around the origin, we flip x and y and reverse the sign of y.
Thus,
The rule to rotate a point P(x, y) after a rotation 90° counterclockwise around the origin is:
P(x, y) → P'(-y, x)
In our case, rectangle PQRS is rotated 90° counterclockwise about the origin.
The rectangle has the coordinates:
We need to determine the coordinates of the point Q’.
Using the rule to rotate a point P(x, y) after a rotation 90° counterclockwise around the origin is:
P(x, y) → P'(-y, x)
Thus, coordinates of the point Q’ will be:
Q(5, 3) → Q'(-3, 5)
Therefore, the coordinates of point Q' are: Q'(-3, 5)
