Hello,
<u>What is the explicit formula for this sequence? -7, -3, 1, 5, ... ?</u>
Aₙ₊₁ = Aₙ + 4 and A₀ = -7
⇒ Aₙ = A₀ + nr = -7 + 4n
Answer:
y=-2.4y
Step-by-step explanation:
First you want to restate the problem.
-3(y+3)=2y+3
Now distribute the negative.
-3y-9=2y+3
Add 3y to both sides.
-9=5y+3
Subtract 3 from both sides.
-12=5y
And solve.
-2.4=y
So see if u can factor out the trinomial.
it's factorable.
(x+3)(×-2)
so divide that factors by (×-2)
(×-2)(×+3)
---------
(×-2)
the (×-2) cancel out, leaving x+3
1000 because it takes 5 1,000's to make 5,000
The answers for that question and probably many more are on this paper
