This is obviously a decreasing sequence. Thus, the common ratio is the fraction 1/4, not the integer 4. Eliminate C and D. Next, at n=1, the value of the 1st term is 16, which is actually 16(1/4)^(1-1) = 16(1) = 16. Thus, B is correct.
Answer:
D
Step-by-step explanation:
y =94..multiply 5 by94 and get 470
Log_10 100 is the same as 10 to the x power is 100
10^x=100
10^2=100
the answer is 2
Answer:
17a + 16 =
Step-by-step explanation:
Add all a's
then all numbers w/o letters
you cannot add them together bc it would be like adding apples to carrots (thats what my teacher said)
If you're looking for the solution to the system of equations, here's how we solve using substitution
We know that y = x - 1, so we can plug that into the first equation giving
2x - 3(x-1) = -1
Now distribute the 3 giving 2x - 3x + 3 = -1. After combining like terms we get -x + 3 = -1. Now subtract 3 from both sides, -x = -4, and multiply both sides by -1 to make x positive. x = 4
Now we can plug that into the second equation to get y
y = x - 1, and we know that x = 4, so y = 4 - 1, y = 3. The solution is (4, 3)
