It's not clear what you're supposed to do, but I would guess that you're asked to find a certain term in the sequence.
Given
you can do that by solving for
explicitly.
So the explicit formula for the
th term is
Answer:
Move all terms that don't have "y
" in it to the right side and solve.
y

Answer:
y = /1/4x/
Hope that this helped! Good luck!
Answer:
8a + 2b + c
Step-by-step explanation:
For subtracting polynomials we just need to operate subtracting the terms with same unknown. In our case we sum/subtract the terms that include a between them, the terms that have b between them and the therms with c between them. So we have:
(13a−4b+8c) - (5a−6b+7c) =?
13a−4b+8c - 5a+6b-7c = ?
Lets operate putting together terms with same unknown:
(13a - 5a) + (-4b +6b) + (8c-7c) =
8a + 2b + c
So, if we subtract 5a−6b+7c from 13a−4b+8c we get 8a + 2b + c
I hope it is clear!
Answer:
B(4, -5)
Step-by-step explanation:
A(-8, 7)
M(-2, 1)
B(x, y)
x-coordinate:
(-8 + x)/2 = -2
-8 + x = -4
x = 4
y-coordinate:
(7 + y)/2 = 1
7 + y = 2
y = -5
B(4, -5)
