Answer:
B / px= k
Step-by-step explanation:
B = kpx
Divide each side by px
B / px= kpx/px
B / px= k
Answer:
n = -4
Step-by-step explanation:
6n + 9 = -3n - 21 - 6
combine like tmers:
6n + 9 = -3n - 27
add 3n to both sides:
9n + 9 = -27
subtract 9 from both sides:
9n = -36
divide by 9:
n = -4
Answer:
B. 16
Step-by-step explanation:
F(3) means we must plug the number "3" into the equation for each x.
(3)^2 + 3(3) -2
9 + 9 - 2
16
Answer:
93
Step-by-step explanation:
First differences increase by 4 each time. The given numbers are a quadratic sequence that can be described by 2n² -2n +9. The 7th term would be 93.
_____
First differences are ...
13-9 = 4, 21-13 = 8, 33-21 = 12, 49-33 = 16, 69-49 = 20
Second differences are ...
8-4 = 4, 12-8 = 4, 16-12 = 4, 20-16 = 4
When second differences are constant, the sequence can be represented by a second-degree polynomial function. The leading coefficient is half the value of the second differences.
