4x-3-8 = 8 4x = 8+8+3 4x = 19 x = 4 and 3/4
Write a pair of number which have a sum of 11 and a product of 24?
4x - 3 = 5 4x = 5 + 3 4x = 8 x = 8/4 x = 2
4x = -3y+8 3y = -4x+8 y = -4/3x+8/3 So the slope is -4/3 or -1 and a 1/3
8 / (5 + a) Example: if a = 3 then 8 / (5 + 3) = 8 / 8 = 1 / 1 = 1
8(4x+ 3)
(3 + -8) - 8
4x-3-8 = 8 4x = 8+8+3 4x = 19 x = 4 and 3/4
Write a pair of number which have a sum of 11 and a product of 24?
12/(8+3)
3y - 4x = 24 The first step is to write it in the standard form (y=mx + c) 3y = 4x + 24 y = (4x + 24)/3 y = 4x/3 + 8 The y-intercept is 8 and the slope/gradient is 4/3
4x - 3 = 5 4x = 5 + 3 4x = 8 x = 8/4 x = 2
-4x + 8 = -4 -4x + 8 - 8 = -4 -8 -4x = -12 -4x/-4 = -12/-4 x = 3
You're there. 4x = 10y - 8.[so subtract 10y from both sides, 4x - 10y = -8]multiply b.s. by -1 , gives -4x +10y = 8
4x = -3y+8 3y = -4x+8 y = -4/3x+8/3 So the slope is -4/3 or -1 and a 1/3
5-4x=x-35-4x+4x=x-3+4x (adding 4x on both side)5=5x-35+3=5x-3+3 (adding 3 on both side)8=5xx=8/5
8 / (5 + a) Example: if a = 3 then 8 / (5 + 3) = 8 / 8 = 1 / 1 = 1
