Hector serves 107 ice cream cones on the weekdays. All you do is subtract the 2 weekend days from the total and you get the answer of the ice cream cones on the other 5 weekdays.
*If needed-- He would have sold about 21 cones each WEEKDAY*

Answer:
any solution of y = 3x -4
Step-by-step explanation:
The two equations describe the same line. There are an infinite number of solutions. Any values of x and y that satisfy either equation will satisfy both equations.
__
The graph shows the lines in different colors and textures, so you can see they are the same line.
Answer:
-1/3
Step-by-step explanation:
y-y/x-x
=
(1- - 1)/(-3-3)= 2/-6 = -1/3
2nd degree and in form
ax^2+bx+c
it is a prabola
the minimum cost is the vertex (every parabola has only one, min or max)
minimum cost is the vertex
vertex=-b/(2a)
a=0.4
b=-208
vertex=-(-208)/(2*0.4)
vertex=208/0.8
vertex=260 (means 260 dresses)
that is x value
subsitute for y value
C(x)=0.4(260)^2-208(260)+37365
C(x)=10325
minimum cost is $10,325
Have in mind that as you cannot take the square root of a negative number, this means that x-4 CANNOT be negative. So it's either 0 or it's positive.
So we proceed like this:<span>x−4≥0</span>
<span>x−4+4≥0+4</span>
<span>x≥4
</span>So the domain is <span>{<span>x|x≥4</span>}
</span>In interval notation, the domain is <span><span>[4,∞)
I hope thi can help you</span></span>
