5x-4y+9y+x-9+7 = 5x + x - 4y + 9y - 9 + 7 = 6x + 5y - 2 ■
Combine like terms: -2x - 4y + 5x - 7y = 3x - 11y -2x + 5x = 3x -4y + -7y = -11y
5x + 4y = 204y = -5x + 20y = (-5/4)x + 5
In math evaluating is where you simplify an expression as much as possible. For example to evaluate 5+2 you simplify it so it is 7. To evaluate 5x+3x+4y you simplify it to 8x+4y.
2x plus 5x simplified is 7x.
2x + 4y - 5x + 3y = 7y - 3x
5x-4y+9y+x-9+7 = 5x + x - 4y + 9y - 9 + 7 = 6x + 5y - 2 ■
Combine like terms: -2x - 4y + 5x - 7y = 3x - 11y -2x + 5x = 3x -4y + -7y = -11y
5x + 4y = 204y = -5x + 20y = (-5/4)x + 5
In math evaluating is where you simplify an expression as much as possible. For example to evaluate 5+2 you simplify it so it is 7. To evaluate 5x+3x+4y you simplify it to 8x+4y.
10x + 2y + 8z - 5x + 4z - 4y = 10x - 5x + 2y - 4y + 8z + 4z = (10 - 5)x + (2 - 4)y + (8 + 4)z = 5x - 2y + 12z
5x+4y = -3 4y = -5x-3 y = -5/4 x - 3 Slope is -5/4.
11x + 2y
2x plus 5x simplified is 7x.
5x+4y = 20 4y = -5x+20 y = -5/4x+5 Therefore: slope is -5/4 and intercept is 5
Yes it is a function. 5x + 4y = 0 the same as: 5x = -4y You can also solve for either variable. x = - ( 4 / 5 ) y y = - ( 5 / 4 ) x
5x+4y = -4 4y = -5x -4 y = -5/4x -1 or as y = -1.25x -1 both of which are in slope-intercept form
