What is the meaning substitution in maths?
now think that:-x=10y=5when you are asked to slove an equation say.....2x+4y=?.then we change the value of x and y into digits so we can work the problem out.now since x=10.then 2x is= 10*2which is 20.y=5then 4y is=5*4which is 20now we have the value of 2X and 4Yso lets use it to get the answer2x+4y=?2x=202y=20so now since we know the values of 2x 4y lets us write their values in the equation insteadso now it is 20+20=?the answer is 40the changing of the algebric structure 2x into 20 in the equation is called substitution
How to write the slope-intercept form of 2x plus 4y equals -8?
2x+4y = -8 4y = -2x-8 y = -1/2x-2 or y = -0.5x-2
What is the ordered pair for 2x plus 4y equals 16 and 2x-4y equals 0?
2x + 4y = 16 <=> 2x + 4y - 16 = 0 2x - 4y = 0 2x - 4y = 2x + 4y - 16 -8y = -16 y = 2 Substituting the known value for y in either of the original equations enables x to be determined. 2x + (4*2) = 16 : 2x = 16 - 8 : x2x = 8 : x = 4 2x - (4*2) = 0 : 2x - 8 = 0 : 2x = 8 : x = 4. The ordered pair satisfying both equations is (4,2)
What is the y-intercept -2x 4y equals 8?
-2x +4y = 8 4y = 2x +8 y = 1/2x +2 Therefore: the y intercept is 2 and the slope is 1/2
Factorise this 8xy-12yz?
(8xy- 12yz) = 4y(2x - 3z) This is the
-2x-4y plus 5x-7y equals?
Combine like terms: -2x - 4y + 5x - 7y = 3x - 11y -2x + 5x = 3x -4y + -7y = -11y
