Answer:
All real values of x except x = 5
Step-by-step explanation:
The questions asks for the domain of [f/g](x).
That is f(x) / g(x) = [x^2 - 25] / [X-5].
The domain of that functions are all the real except those where the denominator becomes zero.
You find those points by doing X - 5 = 0 => x = 5.
Then, the domain of [f/g](x) is all real numbers except x = 5.

Step-by-step explanation:
Answer:
4 double cheese burgers, 2 plain hamburgers, 3 cheeseburgers
Step-by-step explanation:
You have 13 patties, 9 breads, and 11 cheeses. So 4 double cheeseburgers take 8 patties, 8 cheeses, and 4 bread rolls, leaving you with 5 patties, 5 breads, and 3 cheeses. Then 2 plain hamburgers give you 3 patties, 3 breads, and 3 cheeses. And lastly you can make 3 cheese burgers.
So a system of equations means both x and y values are the same for both equations.
Right now, the lines are both = y so you set them equal to each other
x-2=3x+4
Then solve for x
-6=2x
x=-3
Since you have the x value, you can plug that in to either one of the two equations to get the y value
I'll use y=x-2
y= -3 -2
y= -5
Now check it to see if it satisfies both equations
so now you know they meet at (-3,-5)
The answer is (-3,-5) because the point satisfies both equations.
