To simplify the expression (3w + 9x - 15y + 7w + 5x + 7y), first combine like terms. For (w), (3w + 7w = 10w); for (x), (9x + 5x = 14x); and for (y), (-15y + 7y = -8y). Thus, the simplified expression is (10w + 14x - 8y).
This form needed. Y = mX + c2X + 8Y = 408Y = - 2X + 40Y = - 1/4 + 5-----------------------zero out the Y- 1/4X + 5 = 0- 1/4X = - 5X = 20-------------------your X intercept
To simplify the expression (6x - 8y - 5x + 3), combine the like terms. The (6x) and (-5x) combine to give (x). Thus, the simplified expression is (x - 8y + 3).
7x + 8y
To determine slope and Y intercept, solve the equation for y... 5x - 8y + 64 = 0 -8y = -5x - 64 8y = 5x + 64 y = 5/8x + 8 ... now that you have the equation in the form y = mx + b, you can easily see that the slope is 5/8, and the Y intercept is 8.
To simplify the expression (3w + 9x - 15y + 7w + 5x + 7y), first combine like terms. For (w), (3w + 7w = 10w); for (x), (9x + 5x = 14x); and for (y), (-15y + 7y = -8y). Thus, the simplified expression is (10w + 14x - 8y).
(5x -3x) (2y +8y) 2x + 10y
3x - 8y + 2x - 5 - 5y = 5x -13y - 5
8y + 7y = 15ySo [ 8y + 9 + 7y ] = 15y + 9If you want to get fancy and factor that expression, it's 3(5y + 3) .
2x+7y=29 x=37-8y
5x+8y = 40 8y = -5x+40 y = -5/8x+5 in slope intercept form
2x = -7 - 8y
It is 5x + 8y, which cannot be factorised or simplified.
140x / 64y divide 5x/8y = > 40x/64y X 8y/5x Note the change of sign and the inversion of the Right hand fraction. Cancel down by '5x' 8/64y X 8y/1 Cancel down by '8y' 8/8 X 1/1 = 8/8 = 1 The answer!!!!
This form needed. Y = mX + c2X + 8Y = 408Y = - 2X + 40Y = - 1/4 + 5-----------------------zero out the Y- 1/4X + 5 = 0- 1/4X = - 5X = 20-------------------your X intercept
2x + 8y --- has a GCF of 2= 2(x + 4y)
9x plus 8y
