How many solutions does x equals 4 y equals 1 have?
x = 4y = 1Only one solution:x = 1y = 0.25
What is a unique solution in linear equations?
This is the case when there is only one set of values for each of the variables that satisfies the system of linear equations. It requires the matrix of coefficients. A to be invertible. If the system of equations is y = Ax then the unique solution is x = A-1y.
What are the solutions to the nonlinear system of equations y equals 5x and x2 plus y2 equals 26?
y=5xx2+y2=26Substitute the first equation into the second for y.x2 + (5x)2 = 26x2 + 25x2 = 2626x2 = 26x2 = 1x = SQRT(1) = 1 & -1y = 5*1 = 5y = 5*-1 = -5So the solutions are: (1,5) & (-1, -5)
What is the simplified version of 6 - 1y plus 5y - 6y?
6-1y+(5y-6y) = 6-y+(-1y) = 6
How many inches is a 1y shoe?
I think it's 4.8 inches
How is Y-2y8y-6 equivalent to 1?
y-2y8y-6 1y-2y8y-6 1y-6y-6 5y-6 1y
How do you do -x-1y?
The algebraic expression of: -x-1y has the same value as -x-y
How do you solve 2y plus 10 equals 5y-4y?
Here's how it is:2y + 10 = 5y - 4ySolution:2y + 10 = 1y (subtract 5y and 4y)10 = 1y - 2y10 = -1y-1(10 = -1y)y = -10
What is 9y-1y-25?
To simplify this expression, you combine your like terms (9y and 1y). 9y - 1y = 8y 8y - 25 is your answer. It can't be simplified any further than that.
If 3 feet in a yard then why 9 feet for 1 square yard?
Look at it this way: 1y2 is also shown as 1y x 1y So. if you now replace the 1y for 3ft then you get this: 3ft x 3ft And 3 x 3 = 9 3ft x 3ft = 9ft2 equal to 1y x 1y = 1y2 Hope this helps
A number y decreased by 1 is equivalent to which of the following expressionsy - 1y = 1y + 1?
Pls, answer thank you :)
Solve by substition 4x plus 3y equals 1 y equals 2x plus 8?
4x + 3y = 1y = 2x + 8 Take the first part: 4x + 3y = 1y 4x = 1y - 3y 4x = -2y x = -y/2 Substitute x in second part: 1y = 2x + 8 1y = -2y/2 + 8 1y = -1y + 8 2y = 8 y = 4 Substitute y into either part: 1y = 2x + 8 1(4) = 2x + 8 4 - 8 = 2x -4 = 2x x = -2 Therefore: x = -2 y = 4
