Since we know that the 38 is being bisected (which we can tell by the fact that the line hits it perpendicularly), we know that from the intersection to the edge of the circle is 19. From this we can create a right triangle in which the legs are 10 and 19 and the hypotenuse is a radius of the circle. Since x is also a radius of the circle, all we have to do is use that information to find the hypotenuse using the Pythagorean Theorem and we have x. 

Pythagorean Theorem
a^{2} + b^{2} = c^{2}
10^{2} + 19^{2} = x^{2}
100 + 361 = x^{2}
461 = x^{2}
x = \sqrt{461} or about 21.47

Graph the relation and its inverse. Use open circles to graph the points of the inverse. x –3 4 6 9 y 5 6 –9 –10
Tema [17]

Answer:

See attached picture.

Step-by-step explanation:

Graph the function as (x,y) points.

(-3,5)

(4,6)

(6,-9)

(9,-10)

These are graphed in black on the picture.

To graph the inverse, switch the points from (x,y) to (y,x).

(5,-3)

(6,4)

(-9,6)

(-10,9)

These are graphed in red on the picture.

Solve the system of linear equations by elimination.<br><br> −2x−5y=9<br> 3x+11y=4
goldenfox [79]

Answer:

x=-17, y=5. (-17, 5).

Step-by-step explanation:

-2x-5y=9

3x+11y=4

---------------

3(-2x-5y)=3(9)

2(3x+11y)=2(4)

---------------------

-6x-15y=27

6x+22y=8

-----------------

7y=35

y=35/7

y=5

3x+11(5)=4

3x+55=4

3x=4-55

3x=-51

x=-51/3

x=-17

Does anyone know how to do these? I don't understand it at all and need help! It is solving systems of equations by graphing
alexira [117]

Step-by-step explanation: graph both equations where they intersect is the answer write it like this (x,y) the x and the y should be replaced with the numbers you'll get when they intersect. So if they intersected the point where they did if the y is 1 and x is 2 then the answer is (2,1). If they don't intersect at all and are parallel then it is no solution. If your only graphing one line which you aren't in this case but if you were it would be infinitely many.
