Let first number is x
second number be y
one number is four less than a second number: x=y-4
Three times the first is 6 more than 6 times the second: 3x=6y+6
substitute x=y-4 in 3x=6y+6
3x =6y+6
3(y-4)=6y+6
3y-12=6y+6
3y-6y=6+12
-3y=18
y=-6
substitute y=-6 in x=y-4
x=-6-4=-10
so first number is -10
second number is -6
Considering the parabolic equation, the equation for the directrix is given by x = 4.9375.
<h3>What is the equation of a parabola given it’s vertex?</h3>
The equation of a horizontal quadratic function, of vertex (h,k), is given by:
(y - k)^2 = 4p(x - h)
The directrix is given by:
x = h - p.
In this problem, the equation is given by:
(y - 2)² = 0.25(x - 5).
Hence h = 5, p = 0.25/4 = 0.0625, hence the directrix is:
x = h - p = 5 - 0.0625 = 4.9375.

All besides E and F since they have an odd number of edges connecting to them if memory serves
560 + 0.1(1043) =
560 + 104.30 =
664.30 <==
** for the commission...she makes 10% commission on all sales. And if her sales is 1043....then she makes 10% of 1043...turn ur percent to a decimal..." of " means multiply......so 0.1(1043) = 104.30...this is what she made on commission
