Answer:
<u>-53</u>, f(n) = -6(n-1) + 13
Step-by-step explanation:
given the equation to this linear/arithmetic sequence for the nth term: f(n) = -6(n-1) + 13
f(12) = -6(12-1) + 13
f(12) = -6(11) + 13
f(12) = -66 + 13
f(12) = -53
*substitute and simplify*
______________
f(n) = f(1) + d(n-1)
given f(1) = 13, f(2) = 7, and f(3) = 1
7-13 = 1-7 = <u>-6</u> = d
= f(1) + d(n-1)
f(1) = <u>13</u> so
the equation must be f(n) = <u>13</u> <u>-</u><u> </u><u>6</u>(n-1) or -6(n-1) + 13
Answer:
No, it is not.
Step-by-step explanation:
1/5 is equal to 0.2
5/1 is equal to 5 because there are 5 ones.
Answer:
54
Step-by-step explanation:
8*7-12/6=56-2=54
The answer to the first question is D.)
The 6 in front of the parentheses modifies both 'x' and 3
The answer to the second question is D.)
When you plug 4 into the equation, you get 14
3(4) + 2 = 14
12 + 2 = 14
14=14
Hope this helps!
