Do you have a picture or anything that you could show us?
If you meant to write y=23x-4 then none of the lines are perpendicular.
I suspect you intended y=2/3x-4, then line D, y=-3/2x-4 is perpendicular.
For any line y=mx+b, you have to "invert" m to get a perpendicular line. Inverting in this case means: flip numerator and denominator and add a minus sign.
So 2/3 becomes -3/2, hence answer D.
The 'inverted' m is called the opposite reciprocal. That's your word of the day.
Answer:
x = 6
Step-by-step explanation:
(segment piece) x (segment piece) = (segment piece) x (segment piece)
2*x = 3*4
2x = 12
Divide each side by 2
2x/2 = 12/2
x = 6

=(</span>2.3 x 3)(10^-3 x 10^8)
= 6.9 x 10^5
hope it helps
