Find the slope of the line first:
5x - 2y = -6,
y = (5/2)x + 3;
Since we need a line that's perpendicular, m = - (2/5).
The only equation that has the slope of this m is 2x + 5y = -10;
Perimeter of square = 4s perimiter of pentagon= 5s, i guess? its a regular one afterall 4s = P 4 (10) = p 40 = P (40 = 5s)/ 5 8 = s
Sorry I dont know how to answer the second one...
Where S is sales price,
S = .75d
You said which expression CANNOT be used, but I assume you mean can. Let me know if you didn’t.
(Smallest to biggest) 0.3, 0.4, 1/2, 60%, 3/4
Turning all number to decimals
.3, .4, .5, .60, .75
Just divide 2,099,451 by 3501. Houston`s area is 599 square miles
