Tell me wethr pr of line is parll, perp,nthr,5x+2y=3 and 2x+5y=8?

The answer is neither. If they are parallel they must have the same slope and if they are perpendicular the slopes cannot have the same sign. The slopes of the lines are both negative and unequal.\n\nfind the slopes of both lines.\n\n5x+2y =3\ny = (3-5x)/2 = -5x/2 +3/2\nslope 1 = -5/2\n\n2x+5y =8\ny= (8-2x)/5 = -2x/5 + 8/5\nslope 2 = -2/5

y=5x+2\ny=5(2)+2\ny=10+2\ny=12

1. 285000 X 7.481 = 2132085 gal\n\n2.  I'm almost positive that this one is written incorrectly.\n\n3.  Use FOIL\n5x X 5x = 25x^2\n5x X 3 = 15x\n5x X 3 = 15x\n3 X 3 = 9\n25x^2 + 30x + 9\n\n4. w = 12/5x\nw = 900/y^2

Almost.  You would actually include the endpoints 0 and -3 (so you need to use a bracket instead of parentheses).\nD = [0, infinity)\nR = [-3, infinity)

You need to use the distributive property where:\n8(4w+x-6y)=\n8(4w)+8(x)-8(6y)=       \n32w+8x-48y

nope \n5x+5y\n\nthe 4y and -4y cancel each other out

7(5y+5x) = 105\nopen brackets first\n\n35y+35x=105\n\ndivide everything by 35\n\ny+x=3\n\nmake y the subject\n\ny=3-x

x/y = 3/4\n(x+3)/(y+3) = 4/5\n\nso\n3y = 4x and\n4y + 12 = 5x + 15\n\nso\n12y = 16x and\n12y + 36 = 15x + 45\n\nso\n-36 = x - 45\n\nso\nx = 9\n\nso\n3y = 4(9)\ny = 12\n\nSo the new wages are 12 and 15 per hour.\n\n35(12) = 420\n35(15) = 525

3x - 5y = 7\n5y = 3x - 7\ny = (3/5)x -7/5\nA line parallel to it is y = (3/5)x + b\n(6 , -7) on it, so -7 = (3/5)*6 + b\n-35 = 18 + 5b\n5b = -53 and b = -53/5\nThe wished line is y = (3/5)x - 53/5 or\n5y = 3x -53\n\nTh
