Answer: your picture isn't popping up on my screen so when it pops up ill be more than welcomed to help .
Step-by-step explanation:
The way you worded the question kind of confuses me but i'll try to answer.
Think of recursion like climbing a ladder; in this type of sequence you start out somewhere, usually n. So in f(n-1)+1, you take n (where you started) and "step down" once, and then step up once (which brings you back where you were). Remember PEMDAS when doing these.
Answer:
x=-6,x=3
Step-by-step explanation:
x^2-x-18=-4x
Adding both sides by 4x
x^2+3x-18=0
Factoring
(x+6)(x-3)=0
x=-6,x=3
So, this is how we do it O w O<span><span>x = <span>−1</span></span>;<span>y = <span><span>3x</span>+1</span></span></span>Step: Solve <span>x = <span>−1 </span></span>for x:Step: Substitute <span>−1 </span>for x in <span><span>y = <span><span>3x</span>+1</span></span>:</span><span>y = <span><span>3x</span>+1</span></span><span>y = <span><span><span>(3)</span><span>(<span>−1</span>)</span></span>+1</span></span><span>y = <span>−2</span></span>(Simplify both sides of the equation)Answer:<span><span>x=<span>−<span><span>1<span> and </span></span>y</span></span></span>=<span>−<span>2
Hope I helped! :3</span></span></span>
