What is the gradient if 3y equals -5x plus 2?
3y = -5x+2 y = -5/3x+2/3 The gradient is -5/3 and the y intercept is 2/3
What is the SLOPE OF 3Y equals 5X plus 2?
equation is 3y = 5x + 2 standard form is y = mx + b m is the slope adjust the formula for y y = (5/3)x +2/3 slope is 5/3 or 1 and 2/3
How many solutions does y plus 5x equals -2 -15x-3y equals 6 have?
Sounds like a system of equations. Y + 5X = - 2 - 15X - 3Y = 6 substitution using first equation Y + 5X = - 2 Y = - 5X - 2 ==========insert into other equation as this is Y - 15X - 3(- 5X - 2) = 6 - 15X + 15X + 6 = 6 ========================This looks to be a dependent system that has an infinite number of solutions
What is the solution set for 3y equals 5x y equals x plus 2?
3y = 5xy = x + 23y = 5x3(x + 2) = 5x3x + 6 = 5x3x - 3x + 6 = 5x - 3x6 = 2x6/2 = 2x/23 = xy = x + 2 = 3 + 2 = 5Thus, the solution of the set is (3, 5)Check:
8x-7 plus 2x equals 6 plus 5x plus 2?
8x-7 plus 2x equals 6 plus 5x plus 2?
5x plus 3y equals 13 as a ordered pair?
If 5x plus 3y equals 13, the x equals 2 and y equals 1. This is because 5x2=10 and 3x1=3, and 10+3=13.
What is the gradient if 3y equals -5x plus 2?
3y = -5x+2 y = -5/3x+2/3 The gradient is -5/3 and the y intercept is 2/3
What is the solution of 4y-x equals 10 3y plus 5x equals -4?
x=-2, y=2
What is the slope of 5x - 3y equals -6?
5x -3y = -6 -3y = -5x -6 y = 5/3x+2 in slope intercept form
5x plus 3y-2-x plus y plus 2?
5x + 3y - 2 - x + y + 2 = 4x + 4y = 4(x + y)
What is 5x-3y when x equals -2 and y equals -4?
2
What is 2x plus 3y equals -1 5x-2y plus -12 using substitution?
x = -2 and y = 1
What is the SLOPE OF 3Y equals 5X plus 2?
equation is 3y = 5x + 2 standard form is y = mx + b m is the slope adjust the formula for y y = (5/3)x +2/3 slope is 5/3 or 1 and 2/3
Answer for 5x plus y equals 2 5x-3y equals 14?
5x+y = 2 5x-3y = 14 Subtract the bottom equation from the top equation: 4y = -12 y = -3 Substitute the value of y into the original equations to find the value of x: So: x = 1 and y = -3
7x plus 3y equals fourteen and 5x plus 9y equals ten What is the value of x and y?
7x + 3y = 14 5x + 9y = 10 __________ (subtract bottom from top) 2x -6y = 4, therefore 2x = 4 + 6y, therefore x = 2 + 3y Insert x = 2 + 3y into the original equation and calculate 7(2 + 3y) +3y = 14 14 + 21y +3y = 14 24y = 0 y = 0 If y= 0, then x = 2 FINAL ANSWER!
3y plus 5 equals 2x plus 11?
It can't be answered. You need the same variables on both sides. Example: 3y+5x=5 1/2 x (etc.)
How do you find the rate of change for 5x plus 3y equals -2?
Rearrange for y, let f(x) = y, and find the derivative of f(x) with respect to x: 5x + 3y = -2 y = -(5x+2)/3 = f(x) df/dx = -5/3
