3.5 + 3.5 +9+9 = 25. ;) i gotchu again.
City A and City B are about 76.5 miles apart because 51*1.5 = 76.5
You are given triangle RST with vertices R(-3,-1), S(-1,-1) and T(-4,-5).
1. Apply the rotation of 90° counterclockwise about the origin that has a rule:
(x,y)→(-y,x).
Then
- R(-3,-1)→R''(1,-3),
- S(-1,-1)→S''(1,-1),
- T(-4,-5)→T''(5,-4).
2. Second transformation is translation 1 unite up with a rule:
(x,y)→(x,y+1).
So
- R''(1,-3)→R'(1,-2);
- S''(1,-1)→S'(1,0);
- T''(5,-4)→T'(5,-3).
As you can see these points are exactly those from the task condition.
Answer: 1st transfomation is rotation of 90° counterclockwise about the origin and 2nd transformation is translation 1 unite up
Answer:
Step-by-step explanation:
Remark
Since the chords of the circle are equal and non intersecting, The 2 bisecting perpendiculars are going to be equal.
Equation
5x = 7x - 8 Subtract 7x from both sides
5x - 7x = - 8
-2x = - 8 Divide by - 2
x = - 8/-2
x = 5
