In geometry, if 2 angles are congruent, then their corresponding sides are also congruent. So you can have 3x-5=2x+9 & solve for x. Then substitute that value into all the other expressions to get the measures of all 3 sides. From there, you can determine the type of triangle

....
Domain is represented by the x-values of each coordinate indicated by the points on the graph.
Domain (-4, -2, 0, 2)
Range is represented by the y-values of each coordinate indicated by the points on the graph.
Range (-2, -1, 1, 3)
Answer:
x = -1 and y = -3
Step-by-step explanation:
The given equations are :
2x+3y= -11 ...(1)
8x -2y= -2 ...(2)
We need to solve the equations.
Multiply equation (1) by 4.
8x+12y= -44 ...(3)
Subtract equation (2) from (3).
8x+12y-(8x -2y) = -44-(-2)
8x+12y-8x +2y = -42
14y = -42
y = -3
Put the value of y in equation (2).
8x -2(-3)= -2
8x+6 = -2
8x = -8
x = -1
So, the values of x and y are -1 and -3 respectively.
