180-x...... hahaahahaaa
A function--namely a parabola (concave up). To "evaluate" this function you would need an x value and would find the resulting y value. To "solve" this function, you would probably be given a y value and asked to find the corresponding x value(s).
Replace a value for x, then solve for y, to find the corresponding value for y. Repeat for other values of x.
y = 100 - 4x ( a ) Find the value of y when x = 20.
That will depend on what x represents which has not been given.
Well that totally depends on the polygon, if it's a hexagon, triangle, square, the answers are different
Sum of interior angles of a x-gon = (x-2)*180 = 3600 so x-2 = 20 and hence x = 22. GOOD! becus that's what i got! :P
To find the number of degrees in ANY polygon, you can use this formula: (x-2)180 x is the number of sides in your polygon EXAMPLE: A Hexagon: (6 sides-2)180= 720o I hope this helps :D

First find the number of sides of the polygon and let it be x: Rearrange the diagonal formula: 0.5*(x2-3x) = 135 into a quadratic equation Which is: x2-3x-270 = 0 and solving the equation gives x positive value of 18 Therefore the polygon has 18 sides Sum of interior angles: (18-2)*180 = 2880 degrees Each interior angle: 2880/18 = 160 degrees
180-x...... hahaahahaaa
no
There are 5 sides (a pentagon). The perimeter is the length of one side times the number of sides. x * 2.5 = 12.5 and x is 5
The formula to find the value of X would be Y-2X. This would equal to y-9 times 2 X.

No, because 'x' is a variable.
