What are the solutions to the simultaneous equation of 3x plus 2y equals 5x plus 2y equals 14 showing work?
If: 3x+2y = 5x+2y = 14 Then: 3x+2y = 14 and 5x+2y =14 Subtract the 1st equation from the 2nd equation: 2x = 0 Therefore by substitution the solutions are: x = 0 and y = 7
What does reasonableness mean in third grade math?
It means that you can validate the solution by verifying the answer. The answer of 19 for the equation of 47 - 28 = n, is reasonable because 28 + 19 = 47. If the equation is more difficult, showing your work every step along the way to the answer. Just show your work in detail and then checking your solution makes the answer of the math equation reasonable.
What are the solutions to the simultaneous equations of x -2y equals 1 and 3xy -y squared equals 8 showing all appropiate work with answers?
If: x-2y = 1 and 3xy -y^2 = 8 Then: x = 1+2y and 3(1+2y)y -y^2 = 8 Hence: 3y+6y^2 -y^2 = 8 => 5y^2 +3y -8 = 0 Solving the above quadratic equation: y =1 or y = -8/5 Solutions by substitution are: when y=1 then x=3 and when y=-8/5 then x=-11/5
What is blank equals 9?
9
What is the value of c when y equals x plus c is a tangent to the curve y equals 3 -x -5x squared hence finding the point of contact of the line with the curve showing work?
-2
What are the solutions to the simultaneous equation of 3x plus 2y equals 5x plus 2y equals 14 showing work?
If: 3x+2y = 5x+2y = 14 Then: 3x+2y = 14 and 5x+2y =14 Subtract the 1st equation from the 2nd equation: 2x = 0 Therefore by substitution the solutions are: x = 0 and y = 7
Equals force applied times distance moved?
This is the equation for "work."
How can you show your work to solving the equation of 5x-2y equals -10 3x plus 6y equals 66?
There are 2 unknowns
How do you find work in the equation power equals work divided by time?
The definition of work is (force) times (distance). If you mean you're given the equation and you need to solve it for 'work', then you only need to multiply both sides of the equation by 'time', and you'll have (power) x (time) = (work)
What is Work equals Force times Distance?
W= FxD is a balanced equation because Work is Force times distance.
How do you find the x-intercept of y equals 1 over 2x minus 2?
You let y=0 (sub this into the equation), then work out what x equals. i.e 0=1/(2x)-2 becomes 2=1/(2x) etc...
What are the solutions to the simultaneous equations of 7x -8y equals 9 and 11x plus 3y equals -17 showing work?
Equations: 7x-8y = 9 and 11x+3y = -17 Multiply all terms in the 1st equation by 11 and all terms in the 2nd by 7 So: 77x-88y = 99 and 77x+21y = -119 Subtract the 1st equation from the 2nd equation: 109y = -218 => y = -2 Through substitution the solutions are: x = -1 and y = -2
What is the equation for force using work?
The equation for force using work is: Work = Force x Distance. This equation relates the amount of work done to the force applied over a certain distance.
What is the perpendicular distance from the point 7 5 to the staight line equation 3x plus 4y -16 equals 0 showing key stages of work?
Equation: 3x+4y-16 = 0 Perpendicular equation: 4x-3y-13 = 0 Both equations intersect at: (4, 1) Perpendicular distance: square root of (7-4)2+(5-1)2 = 5
What is the perpendicular distance from the coordinates of 7 and 5 to the straight line of 3x plus 4y -16 equals 0 showing key stages of work?
Points: (7, 5) Equation: 3x+4y-16 = 0 Perpendicular equation: 4x-3y-13 = 0 Equations intersect at: (4, 1) Length of perpendicular line: 5
What is three minus negative nine with the work?
3-(-9) Considering a negative plus a negative equals a positive your equation can be rewritten as 3+9 Which equals 12
Is 6 over 15 equals 2 over 5?
Yes. Good work!
