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
How do you do -x-1y?
The algebraic expression of: -x-1y has the same value as -x-y
Why does y plus y equal 2y?
When you have a variable by itself either it be x or y there is always an invisible place holder before it. So a normal "y" would be "1y". So when you put 1y + 1y you get 2y.
What is 1 plus 1 plus 1X plus 1X plus 1X plus 1Y plus 1Y equals what?
1+1+x+x+x+y+y=2+3x+2y
Graph y equals 2x plus 1?
y = 2x + 1 1. Make a table: x = -2; y = -3y = 2x + 1y = 2(-2) + 1 = -4 + 1 = -3 x = -1; y = -1y = 2x + 1y = 2(-1) + 1 = -2 + 1 = -1x = 0; y = 1y = 2x + 1y = 2(0) + 1 = 0 + 1 = 1 x = 1; y = 3y = 2x + 1y = 2(1) + 1 = 2 + 1 = 3 x = 2; y = 5y = 2x + 1y = 2(2) + 1 = 4 + 1 = 5 2. Plug the points (-2, -3), (-1, -1), (0, 1), (1, 3), and (2, 5) in a xy-coordinate system. 3. Draw a line which passes through those points. Thus, the line drawn is the graph of the function y = 2x + 1

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
What is 1 plus 1 plus 1X plus 1X plus 1X plus 1Y plus 1Y equals what?
1+1+x+x+x+y+y=2+3x+2y
What is slope of x plus 12 equals y?
y = x + 12Slope = 1Y-intercept = 12
How many solutions do these equations havex = y + 1y = x + 1?
no s
What is the sum of 5x 2y x-3y?
If you mean: 5x+2y+x-3y then it is 6x-1y
What is the answer to y equals 2x and x plus y equals 3?
Y=2xx+y=3x+(2x)=33x=3x=1y=2x y=2*1y=2
Graph y equals 2x plus 1?
y = 2x + 1 1. Make a table: x = -2; y = -3y = 2x + 1y = 2(-2) + 1 = -4 + 1 = -3 x = -1; y = -1y = 2x + 1y = 2(-1) + 1 = -2 + 1 = -1x = 0; y = 1y = 2x + 1y = 2(0) + 1 = 0 + 1 = 1 x = 1; y = 3y = 2x + 1y = 2(1) + 1 = 2 + 1 = 3 x = 2; y = 5y = 2x + 1y = 2(2) + 1 = 4 + 1 = 5 2.

How would you find the value of y in the expression x cubed plus x squared plus xy plus 8 which is divisable by x minus 1 with no remainder?
The clue is in the question inasmuch that there is no remainder so using the remainder theorem the result must equal zero:- f(x) = x3+x2+xy+8 f(x) becomes f(1) because the divisor is x-1 f(1) = 13+12+1y+8 = 0 because ther's no remainder f(1) = 1y = -10 So y = -10
How many solutions does x equals 4 y equals 1 have?
