First you distribute-3 to -4y and 3 leaving you with 12y+(-9)+7y. Now combine like terms, so your answer is 19y-9
In order to get g(x) you would multiply the equation of f(x) by -1/2.
4x(-1/2)=-2x and -2(-1/2)=1.
Answer:
(c) an = 4·(1/3)^(n-1)
Step-by-step explanation:
The explicit rule for a geometric sequence with first term a1 and common ratio r is ...
an = a1·r^(n-1)
The factor in the recursive rule tells you the common ratio is 1/3, so the explicit rule is ...
an = 4·(1/3)^(n-1) . . . . . . matches choice C
The last row is found by adding the first 2 rows and subtracting the third row for each colum.
last number = 7 + 6 = 13-8 =5
answer: 5
