Answer:
-z/e
Step-by-step explanation:
-x/y = -z/e
I am pretty sure it depends on what your numbers are
Step-by-step explanation:
a) gradient= y2-y1/x2-x1
gradient of AB:
gradient=-4-1/2-3
=-5/-1
=5
gradient of BC:
=-5+4/7-2
=-1/5
b) as the priduct of both gradient is -1 ,both lines are perpendicular.
c) as we have seen lines are perpendicular so it is a right angled triangle.

the idea being, you multiply the "x" by some power of 10 that moves the repeating part to the left of the decimal point and the split it like above.
Answer:
i dunno what that means but i think maybe your keyboard broke so the type of letters is random??
