The endpoints of EF are E(xE , yE) and F(xF , yF). What are the coordinates of the midpoint of EF?
tatyana61 [14]

Answer:

The coordinates of the midpoint of EF is equal to

(\frac{xE+xF}{2},\frac{yE+yF}{2})

Step-by-step explanation:

we know that

The formula to calculate the midpoint between two points is equal to

M=(\frac{x1+x2}{2},\frac{y1+y2}{2})

In this problem we have

(x1,y1)=(xE,yE)

(x2,y2)=(xF,yF)

Substitute the values in the formula

M=(\frac{xE+xF}{2},\frac{yE+yF}{2})

Solve the system by substitution.<br> y = 4x<br> y = 8x - 36
blagie [28]

Answer:

(9,36)

Step-by-step explanation:

Substitute the 4x for the y in second equation.

Basically setting them equal to each other because the both have 'y='

4x = 8x - 36

-4x  = -36 (subtract 8x from both sides)

x = 9         (divide by -4, both sides)

y = 4(9)     (Substitute the x value into first equation)

y = 36

You get paid bi-weekly for only holidays and Sunday not on Fourth of July I make $17.40 an hour. So how much I bring money I bri
Hunter-Best [27]

Well assuming you are not talking about blank holidays there are 22 pure year that you get off. Minus one for the fourth of July would be 21. There are 52 Sundays in a year (as there are 52 weeks in a year), with the slight possibility of a 53 Sunday. I'm going to assume that one wouldn't count though since it occurs every six years (hence leap years).

52+21=73

73 x 17.4 = 1,270.2

1,270.2 x 9 = 11,431.8

11,431.8 dollars yearly.

But to answer your question, there is no real way to answer it because I can't assume you participate in every holiday therefor a "bi-weekly" answer is unpredictable. Sorry I couldn't help you all the way but maybe this will give you a start :)
