Hello!
The number line progresses from negative infinity (extreme left) to positive infinity (extreme right). Beginning at zero, the numbers increase in value as they move to the right and decrease in value as they move to the left.
With this knowledge, we can look at the number 17.2 (a positive number) and conclude that it is placed 17.2 units to the right of zero on the number line.
The opposite of 17.2 would be (-17.2). Again, looking at this number (a negative number), we can conclude that it is placed 17.2 units to the left of zero on the number line.
I hope this helps!
Answer:
3
Step-by-step explanation:
![\frac{18}{2a}](https://tex.z-dn.net/?f=%5Cfrac%7B18%7D%7B2a%7D)
a = 3
![\frac{18}{2(3)}](https://tex.z-dn.net/?f=%5Cfrac%7B18%7D%7B2%283%29%7D)
multiply 2 and 3
2 * 3 = 6
![\frac{18}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B18%7D%7B6%7D)
simplify
18/6 = 3
The distance between any point (x0,y0) on the parabola and the focus (m,n) is the same as the distance between (x0,y0) and the directrix line ax+by+c. The distance between (x0,y0) and focus (a,b) is \sqrt((x-m)^2+(y-n)^2). The distance between (x0,y0) and ax+by+c is |ax0+by0+c|/\sqrt(m^2+n^2). Equalize these two expressions.
The equation you would write would be:
2x+34=187<span />
Answer:
