Answer:
the slope of line j is -1/8, the slope of lines m and n are both 8.
Explanation step by step:
Suppose j is the slope of line j, m the slope of line m and n the slope of line n. Since:
1. line j is perpendicular of line m, so j*m= -1
2. J is perpendicular of line n, so j*n=-1
3. m and n and parallel so m=n
As we want to know the slope of j we clear the equations presented to us in order to find it.
(1) m* n* j = -8, since n=m we have
* j = -8.
we clear j; 
replacing in the equation n*j = -1 we get
n*(-8/n^2) = -1. Thus n = 8. Since j = -1/n = -1/8.
Answer:
2x² +7x - 4
Step-by-step explanation:
(2x-1)(x+4)
2x² + 8x - x - 4
simplify:
2x² +7x - 4
20% in fraction form is....
1) 20 is the percent
2)to put it in a fraction form.......
3) you need to divide it by 100.
4) 20 /100 equals 0.2
5) 0.2 says it's out of 2/10
6) if you want to simplify you can so go ahead: 2/10 >>> (turns into) 1/5
7) 1/5 is your answer...
8) PLEASE GIVE THIS A THANKS AND THE BRAINIEST ANSWER/CROWN...IF NOT...WELL PLEASE DO :) :) :) :) :D :D :D ;D:D
