Answer:
There is a solution. Here's how:
Step-by-step explanation:
So, you work out the problem, and you lay it out here:
5-4+7+1=5-4+7x+1.
First, you start by subtracting 5 from both sides, which cancels both of the 5s. Here's your equation now:
-4+7+1=-4+7x+1
Next, you add 4 to both sides, which makes you identify the identity.
Here's your equation now:
7+1=7x+1
Now, you subtract 1 from both sides.
Here's your equation now:
7=7x
Finally, divide both sides by 7, while identifying the identity.
x=1.
Let n represent the number. You require
7n - 2n = 55
5n = 55 . . . . . . collect terms
n = 11 . . . . . . . divide by 5
The number is 11.
Answer: B = 1
Step-by-step explanation: The first step is to add 6 to both sides of the equation to get -2b = -2
You then divide both sides by negative 2 so you can get a positive
dividing both sides by negative 2 will leave you with 1b = 1
so
b = 1
Answer:
yes
Step-by-step explanation:
Answer:
The option is: <em>all real values except x = 7 and the x for which f(x) = -3</em>
Step-by-step explanation:
As the domain of f(x) is the set of all real values except 7. So it can be written as follows:
Domain of f(x) = { x ∈ R | x ≠ 7}
As the domain of g(x) is the set of all real values except -3. So it can be written as follows:
Domain of g(x) = { x ∈ R | x ≠ -3}
It is a common rule that the domain of a composite function (gºf)(x) will be the set of those input x in the domain of f for which f(x) is in the domain of g.
So, the option is: <em>all real values except x = 7 and the x for which f(x) = -3</em>
