This is called the slope-intercept form because "m" is the slope and "b" gives the y-intercept.

Answer:
x = 3
Step-by-step explanation:
subtract 7 from both sides, then subtract 4x from both sides after
6x +7 = 4x + 13
-7 -7
6x = 4x +6
-4x -4x
2x = 6
divide both sides by 2x
answer x =3
Dividing b 8 is same as mutiiplying by 1/8
144=80+64
1/8(80+64)=1/8(80)+1/8(64)=10+8=18
Answer:
3 letters can be arranged in 26*25*24 = 15600 ways
3 digits can be arranged in 10 * 9 * 8 = 720 ways
So the total number is 15600 * 720 = 11,232,000
So I agree with the number that you obtained
Answer:
Perpendicular: 4, Parallel: -1/4
Step-by-step explanation:
The slope of a line perpendicular to the given line is the opposite inverse of the slope to the line.
First write the equation of the line in slope-intercept form
-x-4y=7
-4y=x+7
y=-(1/4)x-7/4;
The slope to the line is -1/4; Now find the slope of the perpendicular line;
-(-1/4)^-1 = 4
4
The slope of a line parallel to a line is the same as the given slope;
when we calculated the given slope, it was -1/4
The slope of the line parallel to this line is also -1/4
-1/4
