Answer:
(x + 8)^2 + (y + 13)^2 = 13^2
Step-by-step explanation:
Write out (x - h)^2 + (y - k)^2 = r^2. Recognizing that the center is at
(h, k), with h = -8 and k = -13, and that the radius is 13, we get:
(x + 8)^2 + (y + 13)^2 = 13^2
Step-by-step explanation:
because we can also find out the value of x in second equation like this
3x=21
x=21/3
x=7
Answer:
-5
Step-by-step explanation:
-15/3=-5
The rectangle R’S’T’U’ is a 90° counterclockwise rotation of RSTU so options (A) and (C) will be correct.
<h3>What is a rectangle?</h3>
The rectangle is a geometrical figure in which opposite sides are equal.
The angle between any two consecutive sides will be 90 degrees.
Area of rectangle = length × width.
Perimeter of rectangle = 2( length + width).
Given the rectangle RSTU if we plot it then it becomes a major horizontal rectangle.
If we transpose into R’S’T’U’ then it rotates 90 degrees counterclockwise and becomes a major vertical ractangle.
Hence the rectangle RSTU will rotate 90° counterclockwise to form R’S’T’U’.
