5y = 15x -45 Divide by 5 y = 15x/5 -45/5 y = 3x -9 y = mx + b m= 3 6 = -9 The slope is 3 The y intercept is -9
14x2 + 15x + 4 = (7x + 4)(2x +1)
If you mean: y = -15x+60 then 15x+y = 60 When y = 0 then x = 4 When x = 0 then y = 60 Coordinates of the line are: (4, 0) and (0, 60)
3x-15x-y= 45 -12x-y=45 -y=12x+45 y=-12x-45 Solution set: straight line, y-intercept=-45 and slope =-12
No. An equation must be equal to something, that's why its called an equation. 15x = 60 is an equation, in which case x equals 4
15x+25y = 315 25y = -15x+315 y = -0.6x+12.6 which is now in slope-intercept form
5y = 15x -45 Divide by 5 y = 15x/5 -45/5 y = 3x -9 y = mx + b m= 3 6 = -9 The slope is 3 The y intercept is -9
4
When X = 4, 15X = 15 * X = 15 * 4 = 60
If you mean: 3y = 15x+6 then y = 5x+2 whereas 5 is the slope and 2 is the y intercept
14x2 + 15x + 4 = (7x + 4)(2x +1)
If you mean: 3y = 15x+6 then y = 5x+2 whereas 5 is the slope and 2 is the y intercept
hmm it would be -15x+12-8 so on this problem you just simplfy it would be -15x+4
15x + 6y = 45 6y = -15x + 45 (move y to left-hand side) y = (-15/6)x + 45/6 (divide by coefficient of y, 6) y = (-5/2)x + 15/2 (reduce fractions) This is your final answer. your slope is -5/2 and your intercept is 15/2.
15x - 15y = -10 :add 15y to both sides ---> 15x = 15y - 10add 10 to both sides ---> 15x + 10 = 15ydivide both sides by 15 ---> x + 10/15 = y ---> x + 2/3 = yThe final equation y = x + 2/3 in the form y = mx + b, with m =1 and b = 2/3.Slope (m) is 1, and y-intercept (b) is 2/3.
OK, SO 15x-3 = 2x+1 15x - 3 + 3 = 2x + 1 + 3 (add three to each side) 15x=2x+4 (simplIfy) 15x-2x=2x-2x+4 (subtract 2x from each side) 13x=4 (simplify) (13x/13)=(4/13) (divide each side by 13) x≈0.30769231
15x - 3xy = 3x(5 - y) 20 - 4y = 4(5 - y) 15x - 3xy + 20 - 4y = (3x + 4)(5 - y)
