7x + 8y
(x - y + 7)(x + y)
the answer to this problem is -2x^2y^2
7y+3x-21 =0 7y = -3x+21 y = -3/7x+3 The y intercept is 3
y = 6/7x+3 General form of the line equation: 6x -7y+21 = 0
7x + 8y
(x - y + 7)(x + y)
the answer to this problem is -2x^2y^2
7y+3x-21 =0 7y = -3x+21 y = -3/7x+3 The y intercept is 3
y = 6/7x+3 General form of the line equation: 6x -7y+21 = 0
-x + y = -7. There is nothing more that can be done with just one equation and two unknowns.
a + 7y
7x-y-28 = 0
Put in function form. 8X - 7Y = 168 - 7Y = - 8X + 168 Y = 8/7X - 24 0 out Y 8/7X - 24 = 0 8/7X = 24 X = 21 ---------- 0 out X Y = - 24 ----------- (21,-24) X and Y intercepts.
If: 2x-7y = 20 Then: y = 2/7x -20/7 which is now in slope-intercept form
16+7y-8 = 7y+16-8 = 7y+8
To find the inverse of a function, simply switch the variables x and y. So for the function y=7x+3, the inverse would be x=7y+3, or y=(x-3)/7.
