13 plus y?
The expression "13 plus y" represents the sum of 13 and a variable y. It is written in algebraic notation to denote a mathematical operation. The result of this expression will depend on the specific value assigned to the variable y.
What does y mean on a math worksheet that does not define it?
it 's the variable like if i give you the equation 1+y= 13. you would minus 1 on the right side from the 1 and then minus 1 from the 13 then you get this y=12.
How do you do the elimination method for 8x-y20 and -5x y-8?
If this is: 8x - y = 20 -5x = y - 8 8x - y = 20 -5x - y = -8 multiply by -1in order to eliminate y; 8x - y = 20 5x + y = 8 add both equations; 13x = 28 x = 28/13 substitute the value of x into the one of the equations in order to find y. For example, substitute it into the first one; 8(28/13) - y = 20 224/13 - y = 20 multiply both sides with 13; 224 - 13y = 260 224 - 224 - 13y = 260 - 224 -13y = 36 multiply both sides by -1; 13 y = -36 divide both sides by 13; y = -36/13 So the solution set is (28/13, -36/13) Check: 8(28/13) -(-36/13)= 224/13 + 36/13 = 260/13 = 20 -5(28/13) = -36/13 - 8 ? -140/13 = -36/13 -8 ? -140/13 = -36/13 - 8(13/13) ? -140/13 = -36/13 - 104/13 ? -140/13 = -140/13
What is the slope of the line given by the equation below y plus 2 -3(x - 5)?
If you mean y+2 = -3(x -5) then y = -3x+13 whereas -3 is the slope and 13 is the y intercept
What is y equals 6 plus and x equals 7 then y equals?
If you mean: y=6+x/ x=7 Then that is the equation for a line. Put in any number for "x" and "y" will always be 6 more than that. In this case, y=13
What is the standard form of y5x-13?
If you mean y = 5x-13 then in standard form it is 5x-y-13 = 0
8.4 y-4.6 what does y equal?
If you mean: 8.4 = y-4.6 then y = 13
What is the ordered pair for y4x-2 yx plus 13?
If you mean: y = 4x-2 and y = x+13 then x = 5 and y = 18
What is the slope of perpendicular line y-13x?
If you mean y = -13x then the slope of the line perpendicular to it is 1/13

What makes the equation correct 13 equals y-2?
y = 15 so that 13= 15 - 2 y-2 = 13 y-2 +2 = 13 +2 y = 15
What is -y plus 7 equals 13?
-y + 7 = 13 -y = 6 y = -6
How do you solve 3x-y equals 13?
-10
What is the answer for the ordered pair form x plus seven y equals 7 two x plus y equals 8 using substitution?
If you mean: x+7y = 7 and 2x+y = 8 Then by substitution: x = 49/13 and y = 6/13
What is slope intercept form for negative 11 x plus y equals 13?
If: -11x+y = 13 Then: y = 11x+13 whereas 11 is the slope and 13 is the y intercept
How do you do the elimination method for 8x-y20 and -5x y-8?
If this is: 8x - y = 20 -5x = y - 8 8x - y = 20 -5x - y = -8 multiply by -1in order to eliminate y; 8x - y = 20 5x + y = 8 add both equations; 13x = 28 x = 28/13 substitute the value of x into the one of the equations in order to find y. For example, substitute it into the first one; 8(28/13) - y = 20 224/13 - y = 20 multiply both sides with 13; 224 - 13y = 260 224 - 224 - 13y = 260 - 224 -13y = 36 multiply both sides by -1; 13 y = -36 divide both sides by 13; y = -36/13 So the solution set is (28/13, -36/13) Check: 8(28/13) -(-36/13)= 224/13 + 36/13 = 260/13 = 20 -5(28/13) = -36/13 - 8 ? -140/13 = -36/13 -8 ? -140/13 = -36/13 - 8(13/13) ? -140/13 = -36/13 - 104/13 ? -140/13 = -140/13
