Write the range of the function given in the graph in interval notation.<span>However, it is much better to </span>write<span> it in set </span>notation<span> or </span>interval notation<span>. Here's the summary of the domain and </span>range<span> of the </span>given function<span> written in two ways… Because the </span>function<span> involved is a line, I can predict that the </span>range<span> is all y values . It can definitely go as high or as low without any limits.

I need to answer two questions in order to ask a question. sorry that i’m stupid and have no idea how to do this
Multiply the first equation by -2. It turns into 4x+18y=50 and the other one stays -4x-9y=-23. Then you "eliminate" the equations by "adding" them. Set it up like this:
4x+18y=50
+
-4x-9y=-23
4x-4x= 0. 18y-9y= 9y and 50-23= 27
SO: 9y= 27 and y= 3
And then you plug that in to one equation: 4x +18(3)= 50. 4x= 50-(18*3)
4x= -4, so x=-1.
Plug it back in to check!
Hope this helps. Happy solving! :)
Answer:
no, there is not enough information to use AAS congruence theorem to prove the triangles are congruent
