Step-by-step explanation:
Answer:
<em>2(x - 1) - 1 = 3(x + 1) - 6 - x</em>
<em>There are infinitely many solutions.</em>
Step-by-step explanation:
<u>Equations</u>
Suppose Nicky was trying to solve the equation
2(x - 1) - 1 = 3(x + 1) - 6 - x
Operating:
2x - 2 - 1 = 3x + 3 - 6 - x
2x - 3 = 2x - 3
Subtracting 2x:
-3 = -3
This equation is true regardless of the value of x, thus x can have any value. There are infinitely many solutions.
The same result could have come with these equations:
4x - 3 = -3 + 4x
4(x - 1) + 1 = 4(x + 1) - 7
For q(x) = -2x - 2 and r(x) = x^2 + 2
Find the value of q(r(3)).
This is a problem that asks for you to find a function of a function. First things first, you must understand that it is asking you to plug r(3) into q(x) as the value of x.
Let's start by plugging 3 into r(x). Doing so, you'd get
r(3) = 3^2 + 2
Solve it.
r(3) = 9 + 2
r(3) = 11
You can see now that q(r(3)) is really q(11). Plug it in.
q(r(3)) = -2(11) - 2
Solve it.
q(r(3)) = -22 - 2
q(r(3)) = -24
