Answer:
4800
Step-by-step explanation:
A day consist of 24 hours. Half of 24 is 12. 4 x 13 = 12 so 1600 x 3 = 4800.
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
Answer:
y=25x+150 maybe
Step-by-step explanation:
Subtracting is the same as adding, so by subtracting the equations, you get 2x=20, x=10, y: 30-7y=16, 7y=14, y=2, answer:(10,2)
Remember that
try and simpliy each first
4y/14=(2/2)(2y/7)=2y/7
so 2x/7 divided by 2y/7
=
