Answer:
D
Step-by-step explanation:
Answer:
(h, k) will be the coordinates of the center in equation of the circle
1. The counterclockwise rotation by 90° about the origin has rule:
(x,y)→(-y,x).
Then
(-3,-1)→(1,-3).
2. Translation 4 units up has rule:
(x,y)→(x,y+4).
Then
(1,-3)→(1,1).
Answer: after composition of transformations the image point has coordinates (1,1).
Just compare fractions.
$5.25/x = 8.5/100
Then multiple both sides by 100 and both sides by x;
525 = 8.5x
Divide both sides by 8.5
x ≈ $61.77
The measure of one side of a square is (s + 3) inches long. The pair of expressions which both represents the perimeter of this square is:
d) 4( s + 3 ) and (s + 3) + (s + 3) + (s + 3) + (s + 3)
