Same triangles: proportional side are corresponding, congruence angles are respective.
Calculating the length of leg XY:

The number of intersections is the number of solutions
we can see they are paralell so they will never intersect
0
C is the answer
Answer: y=-5/4x+7
Step-by-step explanation: You can see, by looking at the graph, that the slope will be negative, so you can eliminate the options with a positive slope. You can take the first point (0,7) and the second point (4,2) and calculate the slope (the change in y divided by the change in x). 7-2 is five, so that gives us our numerator of the slope. 0-4 is -4, so that gives us our denominator. That gives us a slope of -5/4, so the only answer with that slope is the third option, y=-5/4+7. I hope this helps!
Answer: Just do 2355
Step-by-step explanation: its that
b^2-4ac<0 b^2-144<0 (b-12)(b+12)<0
-12<b<12
