Answer:
an=9+(n−1)3, an=3n+6
Step-by-step explanation:
Arithmetic Sequence:
d=3
This is the formula of an arithmetic sequence.
an=a1+d(n−1)
Step 1: Substitute in the values of
a1=9 and d=3.
an=9+(3)(n−1)
Step 2: Simplify each term.
an=9+3n−3
Step 3: Subtract 3 from 9.
an=3n+6
Answer:
The x-intercepts: (-0.5, 0) and (2, 0)
The y-intercept: (0, -2)
15 1/3 * 12=184 because 15 *12 *1/3
(2,60)(4,120)
slope = (120 - 60) / (4 - 2) = 60/2 = 30 <===
