Answer:
1) first two (A & B)
2. -1,533
Step-by-step explanation:
Sum to infinity is finite when
-1 < r < 1
Option 1: r = -¼
Option 2: r = 27/81 = ⅓
Option 3: r = 3/2
Option 4: r = 17.75/7.1 = 2.5
a = -3
r = -6/-3 = 2
S9 = -3 × (2⁹ - 1)/(2 - 1)
= -1533
0.7(6)^-x = 0.7 * 1 /6^x)
the graphs would be a reflection of each other in the y axis
3z-4=6z-17
-3z-4=-17 (subtracted the 6z from both sides)
-3z=-13 (added the 4 to both sides)
z=
(divided both sides by -3z)
z=
half the perimeter is 32/2 = 16 meters
area = l x w
10+6 = 16
10*6 = 60
length = 10 meters, width = 6 meters
False.
Integers can be expressed as a fraction.
Example: 5=5/1
