X+y = 20
x-y = 4
Solve: Add them two first -> 2x = 24 ->x = 12
So y = 8
A. f(b) = 3+b
b. f(x) = (x+3)²
c. f(x) = (x+3)/(12-x)
d. f(x) = x⁵-4x+6
e. f(x) = -45
f. f(x) = x
the apple tree is 20 and the oak tree is 40

Answer:
9th term geometric sequence (a9) = 1 / 256
Step-by-step explanation:
Given:
Geometric sequence 1,1/2,1/2²
First term (a) = 1
Common ratio (r) = A2 / A1 = (1/2) / 1 = 1/2
Number of term (n) = 9
Find:
9th term geometric sequence (a9)
Computation:
a9 = ar⁹⁻¹
a9 = (1)(1/2)⁸
a9 = (1/2)⁸
a9 = 1/256
9th term geometric sequence (a9) = 1 / 256
Answer:
Obtuse angle
Step-by-step explanation:
Acute angles are less than 90 degrees
Right angles equal 90 degrees
Obtuse angles are greater than 90 degrees and less than 180
