Oh, dude, you just want me to solve those two equations for you? Like, fine, I guess. So, the answer is x = -1 and y = 2. But seriously, why are we doing math right now? Can't we just chill and watch some Netflix instead?
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
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.
(i) <- first part 8y+7-7y = 6+4 8y-7y = 6+4-7 y = 3 (ii) <- second part, put the value of 'y' that you found where y is in the question. 8(3) + 7 - 7(3) = 6+4 24 + 7 - 21 = 10 31-21 = 10 10 = 10 both sides equal the same thing therefore this equation is proved.
The given expression can be simplified to: x-5y
(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!!!!
9x plus 8y
2x + 8y --- has a GCF of 2= 2(x + 4y)
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
8y - 38
