Answer:

x=10, y=20

Step-by-step explanation:

okay so to find x, or the way I did it, we just have to look at the top, we know one line is 180 degrees, and we see three angles, 7x,90, and 20

so 90+20+7x=180

and:110+7x=180

therefore: 7x=70

and finally: x=10

To find y also isn't had if we just look at the blue and green lines we see they are intersecting and opposite angles in intersecting lines are congruent meaning they are the same. So we now know that:

5x+2y=90

and we know x=10

so 5x=50

meaning that: 50+2y=90

therefore: 2y=40

and in conclusion y=20

$28-9x=-12-11x \\\\ -9x+11x=-12-28 \\\\ 2x=-40 \\\\ \boxed{x=-\frac{40}{2}=-20}$

Answer: hello your question is incomplete attached below is the complete question

Answer : g(x), j(x), k(x), f(x), m(x), h(x)

Step-by-step explanation:

The Arrangement of the functions in ascending order ( i.e. starting from the least to the Highest ) is based on the definition of the denominator for all the real values of x and the continuation of the function on the set of real numbers.

when resolving the given functions input the value of x = 5 into the given function to determine the above conditions

g(x) ; has its denominator defined for all real values of x , hence the function g(x) is continuous on the set of real numbers
