Answer:
4th term = -5.
Step-by-step explanation:
a1 = 2
an = 2an-1 - 3
So a2 = 2*2 - 3 = 1
and a3 = 2*1 - 3 = -1
and a4 = 2*-1 - 3 = -5.
Answer:
option D is the correct answer

For the first question, the answer is A. You take 90 and multiply it by 3, then you get the time that it takes for one worker to mow the large park.
For the second question, you take 50 = k/0.25. To find k, you would want to multiply both sides with 0.25 to cancel the 0.25 on k's side. 50 times 0.25 is 12.5. I think C is your answer although I'm not really confident.
Answer:
y =
Step-by-step explanation:
Since y is inversely proportional to x the equation relating them is
y = ← k is the constant of proportionality
To find k use the condition when y = 7, x = 9
k = yx = 7 × 9 = 63
y = ← equation connecting x and y
