Answer:
C
Step-by-step explanation:
9514 1404 393
Answer:
26,244
Step-by-step explanation:
The sequence is geometric with a common ratio of -3. The general term is ...
an = (a1)r^(n-1)
The first term is 4, so we have ...
an = 4·(-3)^(n-1)
For n=9, we find the 9th term to be ...
a9 = 4·(-3)^(9-1) = 4·3^8
a9 = 26,244

<em>Additional comment</em>
When -3 is raised to an even power, the sign of the product is positive, the same as 3 raised to that power.
Answer: y = ½x - 2
Step-by-step explanation:
<u>Slope-intercept form: y = mx + b</u>
- m = slope =
- b = y-intercept ⇒ Substitute in a given point to the function to find b
y = ½x + b
2 = ½(8) + b
2 = 8/2 + b
2 = 4 + b
2 - 4 = b
b = -2
<u>y = ½x - 2</u>
