What is the correct way to write the solution of 2x - 5y equals 9 and 8x - 20y equals 5?
It has no solution!!!The two equations contradict.If you recast the first in terms of x2x-5y=92x=5y+9x=2.5y+4.5Then substitute for x in the second equation8x-20y=58(2.5y+4.5)-20y=520y+36-20y=536=5 (False)which is not true - so the equations have differing values for x and/or y and so are not solveable.

How do you find maximum height when working with quadratic equations?
In a quadratic equation, the vertex (which will be the maximum value of a negative quadratic and the minimum value of a positive quadratic) is in the exact center of any two x values whose corresponding y values are equal. So, you'd start by solving for x, given any y value in the function's range. Then, you'd solve for y where x equals the middle value of the two x's given in the previous. For example:y = x24 = x2x = 2, -2y = (0)2y = 0Which is, indeed, the vertex of y = x2

What is 4-x2x-5?
If you mean: 4-x = 2x-5 then the value of x is 3
If 3x-111 what is the value of x2x?
IF 3X-1=11, WHAT IS THE VALUE OF X 2 + X?
What is the combined term of 2x plus x?
2x+x2x = x+xso 2x+x isx+x+x = 3x
What is the ordered pair of 14x - 2y equals 78 2x - 2y equals 6?
You can answer this by the method of substitution, which means that you find what one variable equals and you substitute it into the second equation to find the other variable.14x-2y=78; solve for y-2y=78-14x; subtract 14x on both sidesy=-39+7x; divide both sides by -2y=7x-39Substitute 7x-39 for y in the second equation.2x-2(7x-39)=6; solve for x2x-14x+78=6; distribute the -2-12x+78=6-12x=-72; subtract 78 on both sidesx=6; divide both sides by -12Now go back to the first equation and for x, substitute 6. You can either substitute in 14x-2y=78 or the y=7x-39, but it's easier where you already have y isolated.y=7(6)-39y=42-39y=3You got that x=6 and that y=3; therefore, the ordered pair is (6,3).

How do you simplify e to the 2xlnx power?
e2xlnx = x2x since ln x is the opposite to e so you just leave the x from the log and the rest of the exponent stays the same.
