Answer:
x= 3/2
Step-by-step explanation:
4x+17-17 = 23-17
4x = 6
4x/4 6/4
4x/4 = 6/4
x = 6/4 (Simplify)
x = 3/2
Answer:

Determine the inverse function
Replace f(x) with y
Swap the positions of x and y
Multiply both sides by -2
Square both sides
Make y the subject
The inverse has been solved. So, we need to replace y with f'(x)
Next, is to determine the interval
Change inequality to
Hence, the inverse function is:
for
Answer:
30 Chairs
Step-by-step explanation:
I will solve this problem using algebra and try to explain in detail.
We can form two equations with the information given to us.
Firstly, 5 times a length of chairs (I will call this unknown length of chairs x), plus 5 left over chairs, equals the total number of chairs (I will call the total number of chairs y).
5x + 5 = y
Secondly, 3 times a length of chairs (I will call this unknown length of chairs x), plus 15 left over chairs, equals the total number of chairs (I will call the total number of chairs y).
3x + 15 = y
Since both equations are equal to y, they are equal to each other
5x + 5 = 3x + 15
Take 5 away from both sides of the equals, and take away 3x from both sides of the equals
5x - 3x = 15 - 5
2x = 10
Divide both sides by 2
x = 5 chairs
Put this back into either the first equation or the second to solve for y
3 (5) + 15 = y
15 + 15 = y
y = 30 chairs
Your answer is 60...
