2x-3y = 4 -3y = -2x+4 y = 2/3x-4/3 So the slope is 2/3 and the intercept is -4/3
4(2x + 3y)(2x + 3y)
-4(7x-3y-z)-(-6)(9x-z+2)
Yes.
answer is y=(4/3)-(2x/3)
2x/3y
2x + 3y = 29x= 4 find x 29x= 4 x = (4/29) sub x into the first part of the sum 2x + 3y = 4 2*(4/29) + 3y = 4 note * means multiply (8/29) + 3y = 4 3y = 4 - (8/29) 3y = (108/29) note 4* 29 minus 8 = 108 y = (36/29) there is probably a quicker way to do this.
2x - 3y = 4This can't be solved, although you can express each variable in terms of the other.x = (4-3y)/2y = (2x-4)/3
2x-3y = 4 -3y = -2x+4 y = 2/3x-4/3 So the slope is 2/3 and the intercept is -4/3
4(2x + 3y)(2x + 3y)
If 2x + 3y = 4, y= (4 - 2x)/3. In function notation, f(x) = (4 - 2x)/3.
1) 2x + 1 = 3y 2) 4 = 3y - 10 this can be re-written as 3y = 4 + 10 Therefore 2x + 1 = 4 + 10 2x = 13 x = 6.5 Sustitute x = 6.5 in equation 1) above 2x + 1 = 3y 2 (6.5) + 1 = 3y therefore 3y = 13 +1 3y = 14 y = 14/3 Now substitute y = 14/3 in equation 2) above and watch what happens! 4 = 3(14/3) -10 4 = 4 Therefore the answer is correct!
-4(7x-3y-z)-(-6)(9x-z+2)
x + y = 1 x + y = 2 x + 2y = 2 x + 3y = 3 2x + 3y = 4 2x + 5y = 5 x - 2y = 2 x - 3y = 3 2x - 3y = 4 a + b + 2c + 3d +e -6f + 2x - 5y = 5
Yes.
2x + 3y = 12 y = -2/3 y + 4 slope is -2/3
If 2x-y = 4 then 6x -3 years =?
