(-1, 0)
Start by adding -2x to both sides of the second equation. Then substitute that equation into the first.
3x+3(2x+2)=-3
Solve the equation for x.
When you've found the value of x, substitute that value into the equation with the isolated y.
y=2(-1)+2
Answer:
C. an= 9(1/3)n-1
Step-by-step explanation:
The decreasing curve means the base of the exponential factor is less than 1, eliminating choices B and D. The value of the term is 9 at n=1, so eliminating choice A.
The general form of the n-th term is ...
an = a1·r^(n-1) . . . . first term a1, common ratio r
so we expect to see an exponent of (n-1) when a1 is the value for n=1. If you match the pattern above to the answer choices, you see the only decision required is whether r=3 or r=1/3. The decaying curve of the graph shows you that r < 1, so the choice is r=1/3 and the formula is ...
an = 9(1/3)^(n-1) . . . . . . . parentheses are needed on the exponent
