Answer:
r=-20/31
Step-by-step explanation:
1)divide the numbers
2) subtract 8 from both sides of the equation

Answer: B) 7 units</h3>
===========================================================
Explanation:
The y coordinates of the two points are the same, so we can subtract the x coordinates and apply absolute value
|R - T| = |-6 - 1| = |-7| = 7
Or we can say
|T - R| = |1 - (-6)| = |1 + 6| = |7| = 7
Either way, the two points are 7 units apart.
You could use the distance formula to get the same answer, but that's definitely overkill in my opinion. The trick mentioned above also could work if the x coordinates were the same, but the y coordinates were different. In any other case, you would have to use the distance formula.
Answer:
y = -3/2x + 5/2
Step-by-step explanation:
Point: (5, -5)
Parallel to: y = -3/2x + 2
Slope= -3/2 (parallel lines have the same slope)
y-intercept = -5 - (-3/2)(5) (y - slope times x) =
-5 + 15/2 = 5/2
Im guessing this is a rectangle? If so it would be
16+16+25+25
32+50
82 is the perimeter
The answer will be x= 12.4
