solve for x (answer)

It's hard to help with this without giving away the game.   Consider the graph of the absolute value of x. It has a vee shape. When x is positive it's a line with slope of +1 and y-intercept of 0. When x is negative it's a line with a slope of -1 and y-intercept of 0. Get some graph...

Hello Craig, For the trigonometric functions sin and cos the constants in the equation determine the magnitude, frequency and phase. For the equation y = 3 * sin( pi*x + pi/2) the amplitude is 3, the frequency is pi and the phase shift is 1/2. A generalized equation would be: (Eq...

If we consider each side of the equation separately we see that they each represent straight lines in the form y=mx+b (the slope-intercept form). The equation y=3x+14 is a line with slope of 3 and y-intercept of 14. The equation y=3x is a line with slope of 3 and y-intercept of 0. These...

Hi Destiny! The first step is to determine where the ten-thousands place is. Most people 'count' the digits from right to left starting at the decimal point: "ones", "tens", "hundreds", "thousands", "ten thousands" -- five places left of the...
