Answer:
(0, -8), (1, -11), (-1, -5)
Step-by-step explanation:
It is convenient to solve for y and choose values of x.
y = -3x -8 . . . . . subtract 3x from both sides of the equation
Now, any integer value of x you choose will result in an integer value of y. Often, it is convenient to choose values near zero.
x = -1, y = -3(-1) -8 = 3 -8 = -5 . . . . solution: (-1, -5)
x = 0, y = -3(0) -8 = -8 . . . . solution: (0, -8)
x = 1, y = -3(1) -8 = -11 . . . . solution: (1, -11)
Answer: The m ∡KLM is: 130° .

Explanation:
__________________________________________________________
(3x − 4) = (4x − 27) ; (Since these are "bisected, congruent angles", they are equal).
⇒ 3x − 4 = 4x − 27 ;
⇒ Subtract "4x" from EACH SIDE of the equation; and add "4" to EACH SIDE of the equation;
⇒ 3x − 4 − 4x + 4 = 4x − 27 − 4x + 4 ;
to get:
⇒ - 1x = -23 ;
⇒ Divide EACH SIDE of the equation by "-1" ; to isolate "x" on one side of the equation; and to solve for "x" ;
⇒ -1x / -1 = -23 / -1 ; to get:
⇒ x = 23;
___________________________________
To find m ∡KLM :
m ∡ KLM = (3x − 4) + (4x − 27) ;
{Note: Remember: (3x − 4) = (4x − 27) } ;
So, plug in our solved value for "x" ; which is: "x = 23" into one of the expressions for one of the congruent angles.
Let us start with: "(3x − 4)" .
(3x − 4) = 3x − 4 = 3(23) − 4 = 69 − 4 = 65 .
By plugging in our solve value for "x" ; which is: "x = 23" ; into the expression for the other congruent angle, we should get: "65" ;
Let us try:
(4x − 27) = 4x − 27 = 4(23) − 27 = 92 − 27 = 65. Yes!
________________________________________________
So to find m ∡KLM:
(3x − 4) + (4x − 27) = 65 + 65 = 130° .

Alternate method:

At the point which we have:
_______________________________________________
To find m ∡KLM :
m ∡ KLM = (3x − 4) + (4x − 27) ; and at which we have our solved value for "x" ; which is: "x = 23" ;
_______________________________________________
We can simply plug in our known value for "x" ; which is: "23" ; into the following:
m ∡ KLM = (3x − 4) + (4x − 27) = [(3*23) − 4] + [(4*23) − 27] ;
= (69 − 4) + (92 − 7) = 65 + 65 = 130° .
_____________________________________________________________
{Note: Using this method, we determine that each angle is equal; that is, "65° ".}.

H=-6 is the answer after substituting
Answer:
where is the question here n a graph ?????
Answer:
265°
Step-by-step explanation:
I think we have to minus 200 - 115 = 85
then plus them with 85 and 95 so
85 + 85+ 95 = 265°C
i hope this helps a little bit
