Answer:
C. 5(x-6)=20
Step-by-step explanation:
we can represent the value of x decreased by 6 times 5 as 5(x-6) and then show that that is equal to 20.
It is the same as what you had said and so a rational number is the same thing as a rational number and nothing changes.
Step-by-step explanation:
the x distance from A to B is 3 (from -1 to 2), and the y distance is 15 (from -4 to 11).
the x distance from C to D is also 3 (from 1 to 4), but the y distance is 9 (from 1 to 10).
so, the slopes are different
AB : 15/3 = 5
CD : 9/3 = 3
and the lines are therefore not parallel.
perpendicular slopes are simply inverting y and x in the ratio and flip the sign (from - to + and vice versa). but that is not the case here either (just to start - both slopes are positive).
so, the 2 lines are "neither".
