Answer:2x with and exponent of 3 -9x with and exponent of 2 +7x +6
Step-by-step explanation:
Step-by-step explanation:
The point A(2, 4) is
rotated 270 ccw, so the A' should be on the 4th quadrant
=> A' (4, -2)
Answer:
The formula is ⇒ 
Step-by-step explanation:
∵ The sequence is -1/2 , -3/10 , -9/50 , -27/250
∵ (-3/10) ÷ (-1/2) = 3/5
∵ (-9/50) ÷ (-3/10) = 3/5
∴ It is a geometric sequence
∴ The formula is Tn = ar^(n - 1)
Where a is the first term , r is the constant ratio between each two consecutive terms and n is the position of the number
∴ Tn = -1/2 ( 3/5)^(n - 1)
∴
