Subtract 4Q from both sides combine 5 Q and minus 4q to get Q add 3p to both sides subtract 4 from both sides subtract 4 from -2 to get to -6
Nope. its y=3x-1. the y intercept is -1, so we put that at the end. And if we take 2 points on the line and use y/x, we get 3/1 or 3, and this is our slope. Also the line is going up so its not negative
Answer:
slope = -4/5 and y-intercept = -9/5
Step-by-step explanation:
make y the subject of the formula
I think it's 5x(x^3+4x^2-21x)
Answer:
tn = 243·(1/3)^(n-1)
Step-by-step explanation:
The recursive formula tells you the first term (243) and the common ratio (1/3). You can put these numbers into the general formula for the n-th term of a geometric sequence:
an = a1·r^(n-1) . . . . . where a1 is the first term and r is the common ratio
You want the n-th term of your sequence to be called tn, so ...
tn = 243·(1/3)^(n-1)
