60 x 13 = 780
780 divided by 15 = 52
so therefore 52/60 = 13/15
The first one is none of above, it is vertical opposite angles.
the second to the left is also none of above, since the 2 lines are not parallel to each other.
the third one in the right is corresponding
the fourth one is alternative exterior
the last one is none of above because again the lines aren't parallel
Answer:
x=-3,x=9
Step-by-step explanation:
x^2-6x-20-7=0
x^2-6x-27=0
x^2-(9-3)x-27=0
x^2-9x+3x-27=0
x(x-9)+3(x-9)=0
(x+3)(x-9)=0
x=-3,x=9
The slope is 5/1. This is because it goes up 5 units and right one unit. This corresponds with the fact that slope is the rise/run on a line.
