3x+4y=-14
is the same as y = -3/4 x - 14/4 slope, m = -3/4
perpindicular slope = - 1/m = 4/3
point slope form of new line thru 5,7
y-7 = 4/3 (x-5) re-arrange
y = 4/3 x - 20/3 + 7
take it from here......
Triangle side rule any two sides summed must be greater than third side
soooo longest side cannot be greater than or equal to 1/2 of the perimeter, because the other two sides will not add up to be greater than...

Missing important numbers !
f(x) = y = 12.5 x
Rate of change = slope = -3
or the derivative of -3x is -3
or take two points say 2 and 4
-3(2) = -6 -3(4) = -12 r.o.c = (-12 - - 6) /2 = - 3
There are two unit rates available pages per day 99/3 = 33 pages/day which I expect is what you want
but there is also days per page 3 days/99 pages = 1/33 days /page
5 digits can make 10 000 plates (00000 - 99999)
multiplied by one of four letters = 40 000 plates
1/3 of the way from 0 to 9 is 3 = x
1/3 of the way from0 to 6 is 2 = y sum = 5
Wording of the question is a bit unclear:
If 'width ' is the height of the screen
then 'length' would be 42 sin 28 this is the measure across the bottom of the screen
If 'width' and 'length' are the same thing then the measure across the bottom of the screen would be 42 cos 28
10000 = d ( 1+ .04/2)21*2 Solve for d = the deposit to make
