5x + 4 - 3x + 5 + 2x - 9 = 4x
25x2 + 40x + 16 = 25x2 + 20x + 20x + 16 = 5x(5x + 4) + 4(5x + 4) = (5x + 4)(5x + 4) or (5x + 4)2
5x = 5 times 9, 2y = 2 times 4 so 45 - 8 ie 37
5x² - 18x + 9 = (5x² - 15x) - (3x - 9) = 5x(x - 3) - 3(x - 3) = (5x - 3)(x - 3).
5x - 9 = 4x 5x - 4x - 9 = 4x - 4x x - 9 = 0 x - 9 + 9 = 0 + 9 x = 9
4(5x + 3) - 9 = 20x + 3
if you mean 5x-4-3x=9 then x= 6.5
(5x+4)(9x+9) FOIL First (5x*9x=45x**2) Outside (5x*9=45x) Inside (4*9x=36x) Last (4*9=36) 45x**2+45x+36x+36 45x**2+81x+36 9(5x**2+9x+4x)
5x + 4 = 10x - 5 10x - 5x = 4 + 5 5x = 9 x = 1.8
9
y - 9 = -5(x - 4) y - 9 = -5x + 20 y = -5x +20 +9 y = -5x +29
5x + 9 = 4Subtract 9 from each side:5x = -5Divide each side by 5:x = -1
5x + 4 - 3x + 5 + 2x - 9 = 4x
9
5x-9Substitute 4 in for x5(4)-9=Solve.9-9=0the answer is zero.The answer is not zero you added when you were supposed to multiply so the real answer is 11.
-4
To answer this question we need to first get the slope of the line 5x-4y=9 by rearranging it in the form of y=mx+b: 5x-4y=9 4y=5x-9 y=(5/4)x-9/4 Since the slope of parallel lines are negative reciprocals of each other, the negative reciprocal of 5/4 is -4/5, therefore the slope of a line parallel to the line 5x-4y=9 is -4/5
