Answer:
y = 1/4x -3
Step-by-step explanation:
The inverse relation can be found by interchanging y and x, then solving for y.
x = 4y +12
x = 4(y +3) . . . . factor out 4
x/4 = y + 3
x/4 -3 = y
y = (1/4)x -3 . . . . the inverse relation
You would the amount times by

Answer:
True
Step-by-step explanation:
The n th term rule for an arithmetic sequence is
= a + (n - 1)d
where a is the first term and d the common difference
here d = 9 - 7 = 2 and a = 7, thus
= 7 + 2(n - 1)
