I believe with vertical angles, they are equal to each other.

Therefore,

2y + 5 = 4y

subtract 2y from both sides

5 = 2y

divide 2 from both sides

y = 5/2

2y+5=4y they are vertical angles which are eqaul
y=5/2

A sequence has the recursive definition f(1)= 2/3, f(n)= f(n-1)•

Advocard [28]

Answer:

Explanation:

f(3) = (3 - 1) • 3/2
f(3) = 2 • 3/2
f(3) = 3

f(4) = (4 - 1) • 3/2
f(4) = 3 • 3/2
f(4) = 9/2

f(5) = (5-1) • 3/2
f(5) = 4 • 3/2
f(5) = 6

f(6) = (6-1) • 3/2
f(6) = 5 • 3/2
f(6) = 15/2

f(7) = (7-1) • 3/2
f(7) = 6 • 3/2
f(7) = 9
