There is no picture showing a graph, I'm very sorry but you have to press the bottom of the screen where it has a paperclip thing and then you have to add a picture from your gallery. I. sorry I couldn't answer you're question but you can redo it with the photo of the graph and I will try to answer it.
Let x and y be the angles X= 3•y-8 X+ y = 180 Substitute first relationship in second 3y-8+y=180 4y=180+8 Y =188/4= 47 degrees X= 180-47=133 degrees The measure of the large angle is 133 degrees
Let’s start with -4(-3x + 11) so, -4•-3x is 12x,because multiplying 2 negatives creates a positive. As for -4•11, it is -44. So, it should be 12x + -44. I hope this helps!
