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 slope of 15x-15y equals -10?
15x - 15y = -10 :add 15y to both sides ---> 15x = 15y - 10add 10 to both sides ---> 15x + 10 = 15ydivide both sides by 15 ---> x + 10/15 = y ---> x + 2/3 = yThe final equation y = x + 2/3 in the form y = mx + b, with m =1 and b = 2/3.Slope (m) is 1, and y-intercept (b) is 2/3.
What is the gcf of 17xy and 15x squared z?
The terms can be factored to: 17xy = 17 * x * y 15x²z = 3 * 5 * x * x * z The only term that 17xy and 15x²z have in common is x. Therefore, x is the GCF of these terms.
What does rate of change mean in math?
A rate of change in a variable Y, if not further qualified, is the change in Y for a unit change in time. However, the rate of change may be defined in terms of a unit change in some other variable (X). In graphical terms, the rate of change for a straight line is its gradient whereas for a curve, the rate of change at a point is the gradient of the tangent to the curve (if a tangent can be defined).
What is a unit rate with denominator of 1 unit?
It is the definition of a unit rate.
15x plus 15yequals15x plus y?
I think the question is asking "what value of y satisfies the equation 15x + 15y = 15x + y ? " If so, the answer is y = 0.
How can you find a unit rate when give a rate?
If you are given a rate of x to y then the equivalent unit rate is x/y to 1.
How do you get a rate as a fraction?
Simplify the fraction to its simplest form.If this is 1/y then the unit rate is "1 unit per y units".If it is x/1 then the unit rate is "x units per unit".If it is x/y then the units rate is "(x/y) units per unit".
What is slope for -15x - 4?
If you mean: y = -15x-4 then the slope is -15 and the y intercept is -4
Can you show me how to graph y equals -15x 60?
If you mean: y = -15x+60 then 15x+y = 60 When y = 0 then x = 4 When x = 0 then y = 60 Coordinates of the line are: (4, 0) and (0, 60)
How do you change 15x-y-45 into slope intercept?
5y = 15x -45 Divide by 5 y = 15x/5 -45/5 y = 3x -9 y = mx + b m= 3 6 = -9 The slope is 3 The y intercept is -9
Y=15x+40?
55
Factor the polynomial 15x - 3xy plus 20 - 4y by grouping?
15x - 3xy = 3x(5 - y) 20 - 4y = 4(5 - y) 15x - 3xy + 20 - 4y = (3x + 4)(5 - y)

3X -15X - y equals 45?
3x-15x-y= 45 -12x-y=45 -y=12x+45 y=-12x-45 Solution set: straight line, y-intercept=-45 and slope =-12
How do you find the unit rate to y-2x?
The question contains an expression, not an equation. An expression cannot have a unit rate.
What is the greatest common factor of -30x to the second power y to the third plus 15x to the second y to the second plus 60x to the fourth y to the third?
The GCF is 15x^2y^2
