If x = -b/2a, then 2a = -b / x so a = -b / 2x or a = b / -2x
So the denominator is -2x because it has to take the minus sign that the numerator refused to take ;-)
Answer:
The linear equation is the equation of straight line. where m is the slope of the line and c is the y-intercept. Thus, the y-intercept is expressed as (0, c). That is where the graph intercepts the y-axis (thus, the x value would be 0).
Step-by-step explanation:
14, 48, 50
These lengths are double the Pythagorean triple of 7, 24, 25. A triangle with side lengths that are a Pythagorean triple will be right angled.
