Finding the slope and y- intercept of a line 9y plus 2x plus 3 equals 13 plus 2x?
9y + 2x + 3 = 13 + 2xSubtract 2x from each side:9y + 3 = 13Subtract 3 from each side:9y = 10Divide each side by 9:y = 10/9The graph is a straight horizontal line. The slope is zero. The y-intercept is [ y = 10/9 ).
What equations describes a line that is perpendicular to 2x plus 9y equals 9?
Any one of them that has a slope of 9/2 or 4.5
What value of b will make 2x-3y equals 5 and 9y plus bx equals 4 parallel?
2x - 3y = 5 => 3y = 2x - 5 has a gradient of 2/3 9y + bx = 4 => 9y = -bx + 4 has a gradient of -b/9 The two gradiends must be the same if the two lines are parallel: 2/3 = -b/9 so that b = -6
What expression is equivalent to 7x plus 4y - 9x plus 5y?
It can be simplified to: 9y-2x
What does y equal if 9y plus 4.8 equals 17.4?
9y = 12.6 y = 1.4
What is 2x plus 9y - 6x?
9y - 4x
Finding the slope and y- intercept of a line 9y plus 2x plus 3 equals 13 plus 2x?
9y + 2x + 3 = 13 + 2xSubtract 2x from each side:9y + 3 = 13Subtract 3 from each side:9y = 10Divide each side by 9:y = 10/9The graph is a straight horizontal line. The slope is zero. The y-intercept is [ y = 10/9 ).
How many values of x and y satisfy the equations 2x plus 6y equals 12 and 3x plus 9y equals 18?
2X + 6Y = 12 3X + 9Y = 18 try elimination - 3(2X + 6Y = 12) 2(3X + 9Y = 18) - 6X - 18Y = - 36 6X + 18Y = 36 ================= I will say this system is dependent and an infinite number of solutions can be found.
Y-8x plus 9y equals?
Y-8x plus 9y equals 10y-8x.
What is 2x plus 3y plus 4x plus 9y?
To simplify the expression 2x + 3y + 4x + 9y, you first combine like terms. Adding the coefficients of x terms gives 2x + 4x = 6x. Similarly, adding the coefficients of y terms gives 3y + 9y = 12y. Therefore, the simplified expression is 6x + 12y.
What equations describes a line that is perpendicular to 2x plus 9y equals 9?
Any one of them that has a slope of 9/2 or 4.5

2x - 3y = 5 => 3y = 2x - 5 has a gradient of 2/3 9y + bx = 4 => 9y = -bx + 4 has a gradient of -b/9 The two gradiends must be the same if the two lines are parallel: 2/3 = -b/9 so that b = -6
What is 6x plus 3y plus 6y-2x?
6x + 3y + 6y - 2x = (6x - 2x) + (3y + 6y) = 4x + 9y
Simplify 3x - 2y plus 9 plus 9y - x?
3x-2y+9+9y-x = 2x+7y+9
What expression is equivalent to 7x plus 4y - 9x plus 5y?
It can be simplified to: 9y-2x
Factor 6xsquare plus 13xy - 63ysquare?
(3x - 7y)(2x + 9y)
What does y equal if 9y plus 4.8 equals 17.4?
9y = 12.6 y = 1.4
