None, because there is visible equation!
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals", "squared", "cubed" etc. Please use "brackets" (or parentheses) because it is impossible to work out whether x plus y squared is x + y2 of (x + y) 2.
x^2 + 14x + 40 factorises as (x + 10)(x + 4) so the roots are x = -10, -4.
If: 14x = 56Then x = 56/14Therefore: x = 4
Equations: 7x+4y = 9 and 2x+3y = 1 Multiply all terms in the 1st equation by 2 and all terms in the 2nd equation by 7 So: 14x+8y = 18 and 14x+21y = 7 Subtract the 1st equation from the 2nd equation: 13y = -11 => y = -11/13 By substituting y = -11/13 into any of the equations x = 23/13 Therefore the solutions are: x = 23/13 and y = -11/13
10 + 14x - 3 is pretty much the same thing as 7 + 14x. You can't solve this problem without knowing what x is or what the equation equals out to. For example, if 10 + 14x - 3 = 21, x would equal 1.
That doesn't factor neatly. Applying the quadratic equation, we find two real solutions: (-7 plus or minus the square root of 91) divided by 2 x = 1.269696 x = -8.269696

That looks like a linear equation (no quadratic or higher terms), so you can expect it to have a single solution. However, actually solving the equation is not difficult; do it, to confirm this.
How about finding the solutions of the quadratic equation: x^2-14x+49 = 0
x^2 + 14x + 40 factorises as (x + 10)(x + 4) so the roots are x = -10, -4.
14x = 5 x = 5/14
It is an equation and the value of x is -9.25
Since y=14x is a perfect linear relation, the correlation would be 1.
6x-14x+16=27+11 answer: 4
If you mean: y = 14x+2 then the slope is 14 and the y intercept is 2
If: 14x = 56Then x = 56/14Therefore: x = 4
