9y plus 3 equals 5y plus 13?
9y+3 = 5y+13 9y-5y = 13-3 4y = 10 y =2.5
-3x-y equals 3 and -3x-5y equals -21 please help me solve the above equation through the substitution method.?
-3x = 3 + y 3 + y - 5y = -21 -4y = -24 y = 6 x = -3
How many ordered pairs of positive integers satisfly the inequality 4x plus 5y20?
If the inequality is > (greater than) or >= (greater than or equal to), then there are an infinite number of solutions. So let the inequality be < (less than) or <= (less than or equal to) x = 1: 5y <= 16 so y = 1, 2 or 3 x = 2: 5y <= 12 so y = 1 or 2 x = 3: 5y <= 8 so y = 1 x >= 4: 5y <= 4 no solution. So whether the inequality is < or <= there are 6 ordered pairs.
Factor 5y3 - 125y?
5y3 - 125y = 5y(y2-25) = 5y (y+5)(y-5)

What is the solution of this linear system 3x plus 5y equals -1 2x-5y equals 16?
3x + 5y = -1 2x - 5y = 16 Add the two equations: 5x = 15 or x = 3 Substitute for x in the first equation: 3*3 + 5y = -1 15 + 5y = -1 5y = -10 so y = -10/5 = -2 The solution is (x, y) = (3, -2)
How do you factor 2y2-5y-3?

How do you expand an equation?
Multiply the coefficient by all the values inside the brackets.Example 1:2(y+1)= 2 X y + 2 X 1= 2y + 2Example 2:3 X 5y(y+4)= 3 X (5y X y) + (5y X 4)= 3 X 5y2 + 20y
What is the equation of the line passing through 3 1 and is parallel to 3x plus 5y equals 6 showing work?
If: 3x+5y = 6 Then: y = -3/5x+6/5 which means it has a slope of -3/5 Parallel equation: y-1 = -3/5(x-3) => 5y-5 = -3(x-3) => 5y = -3x+14 Or as: 3x+5y = 14
5y2 - 2y - 3 Factor completely?

What is the slope-intercept form of the line x plus 5y equals 3?
x + 5y = 3x - x + 5y = -x + 35y = -x + 3(5y)/5 = (-x + 3)/5y = -(1/5)x + 3/5 The slope-intercept form, y = mx + b, where (slope) m = - 1/5 and (y-intercept) b is 3/5.
8 plus y equals 7 plus 5y?
8+y = 7+5y y-5y = 7-8 -4y = -1 y = 1/4
What is the y-intercept of 6x-5y15?
-3 Solution Method: ------------------ 1. Clarify the problem: What is the y-intercept of 6x-5y=15? 2. Recall what the "y-intercept" is: "the y-intercept is the y coordinate when the x value = 0 or the b value in the slope-intercept form (y = mx + b (b=the y-intercept value)) of the point-slope equation (y - y1 = m(x-x1). 3. Input the x coordinate into the equation & find the y value: 6(0)-5y=15 0-5y=15 -1/5 * -5y = 15 * -1/5 y = - 3 (this is your y-intercept value) OR when (y = mx + b), then b = the y-intercept value) 6x - 5y = 15 -6x - 5y = -6x + 15 -5y = -6x + 15 -1/5 * 5y = (-6x + 15) * -1/5 y = 6/5x - 3 (-3 = the y-intercept value) ================ A2. I am assuming you mean 6x - 5y = 15. Since the y intercept is at x=0, plugging x=0 into the equation gives 6(0)-5y=15. Since 6(0)=0, this gives -5y=15. Dividing both sides by -5 gives y=-3. Remember, the y-intercept is a point, so, since x=0, the point is (0,-3). A1?: ---------------------- Another way ---------------------- The equation is 6x - 5y = 15 The equation for graphing a line is y = mx + b where b is the y-intercept. Try to get it in this form - 6x - 5y = 15 (Add 5y on both sides) 6x = 15 + 5y (Subtract 15 from both sides) 6x - 15 = 5y (Since we need to get a single y, divide both sides by 5) (6x)/5 - (15)/5 = (5y)/5 (Simplify) 6/5x - 3 = y Therefore, the slope is 6/5 and the y intercept is -3. Good luck!
