Answer:
points 4 , 1 ,25 , opposite of 3 , -1/2To Find
Step-by-step explanation:
Answer:
-1
Step-by-step explanation:
y-5 =-x
change it to y=mx+b form
y= -x+5 (m is slope = -1)
-1 is your slope
The rotations that will carry the equilateral triangle in discuss onto itself are;
- 90° counterclockwise rotation about its center P.
- 270° counterclockwise rotation about its center P.
<h3>Which rotations will carry this equilateral triangle onto itself?</h3>
It follows from the task content that the rotation which produces the desired output in which case, the rotation maps exactly unto the equilateral triangle is required.
On this note, when the rotation is 90° and 270° about the center P in which case, the rotation can be clockwise or anticlockwise, the desired result is obtained.

Answer:
a =
, r = 
Step-by-step explanation:
The sum to infinity of a geometric progression is
; | r | < 1
Thus for first progression
= 6 ( multiply both sides by (1 - r) )
a = 6(1 - r) → (1)
Second progression
= 7 ← multiply both sides by (1 - r² )
2a = 7(1 - r² ) = 7(1 - r)(1 + r) ← difference of squares
2a = 7(1 - r)(1 + r) → (2)
Substitute a = 6(1 - r) into (2)
2(6(1 - r) = 7(1 - r)(1 + r)
12(1 - r) = 7(1 - r)(1 + r) ← divide both sides by (1 - r)
12 = 7(1 + r) = 7 + 7r ( subtract 7 from both sides )
5 = 7r ( divide both sides by 7 )
r = 
Substitute this value into (1)
a = 6(1 -
) = 6 ×
