Answer:
None.
Step-by-step explanation:
4(x-1)-x = 3(x+5)-11
4x-4-x=3x+15-11
we combine like terms.
4x-x-4=3x+14
3x-4=3x+14
we then isolate the variables.
3x-4=3x+14
+4 +4
3x=3x+18
-3x -3x
0≠18

<h2>Evaluating Composite Functions</h2><h3>
Answer:</h3>
<h3>
Step-by-step explanation:</h3>
We can write how will be defined but that's too much work and it's only useful when we are evaluating with many inputs.
First let's solve for first. As you read through this answer, you'll get the idea of what I'm doing.
Given:
Solving for :
Now we can solve for , since , .

Description
DescriptionIn mathematics, a zero of a real-, complex-, or generally vector-valued function, is a member of the domain of such that vanishes at; that is, the function attains the value of 0 at, or equivalently, is the solution to the equation. A "zero" of a function is thus an input value that produces an output of
Replace the x with 9, and the y with 1.
(x · y²)/-5 becomes (9 · 1²)/-5
1² is just 1, so you're doing 9 × 1 (which is = 9) over -5.
Therefore, your final answer is -9/5.
