Answer:
Midpoint of side EF would be (-.5,4.5)
Step-by-step explanation:
We know that the coordinates of a mid-point C(e,f) of a line segment AB with vertices A(a,b) and B(c,d) is given by:
e=a+c/2,f=b+d/2
Here we have to find the mid-point of side EF.
E(-2,3) i.e. (a,b)=(2,3)
and F(1,6) i.e. (c,d)=(1,6)
Hence, the coordinate of midpoint of EF is:
e=-2+1/2, f=3+6/2
e=-1/2, f=9/2
e=.5, f=4.5
SO, the mid-point would be (-0.5,4.5)
Electronegativity<span> is a measure of the tendency of an atom to attract a bonding pair of electrons. The Pauling scale is the most commonly used. Fluorine (the most</span>electronegative<span> element) is assigned a value of 4.0, and values range down to caesium and francium which are the least </span>electronegative<span> at 0.7.</span>

First, simplify
![\frac{2}{7} x](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B7%7D%20x)
to
![\frac{2x}{7}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2x%7D%7B7%7D%20)
/ Your problem should look like:
![-\frac{2x}{7}](https://tex.z-dn.net/?f=%20-%5Cfrac%7B2x%7D%7B7%7D%20)
+ 6 +
![\frac{1}{7} x](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B7%7D%20x)
= 18
Second, simplify
![\frac{1}{7} x](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B7%7D%20x)
to
![\frac{x}{7}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B7%7D%20)
/ Your problem should look like:
![- \frac{2x}{7}](https://tex.z-dn.net/?f=-%20%5Cfrac%7B2x%7D%7B7%7D%20)
+ 6 +
![\frac{x}{7}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B7%7D%20)
= 18
Third, simplify
![- \frac{2x}{7}](https://tex.z-dn.net/?f=-%20%5Cfrac%7B2x%7D%7B7%7D%20)
+ 6 +
![\frac{x}{7}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B7%7D%20)
to
![- \frac{x}{7}](https://tex.z-dn.net/?f=-%20%5Cfrac%7Bx%7D%7B7%7D%20)
+ 6 / Your problem should look like:
![-\frac{x}{7}](https://tex.z-dn.net/?f=%20-%5Cfrac%7Bx%7D%7B7%7D%20)
+ 6 = 18
Fourth, regroup terms. / Your problem should look like: 6 -
![\frac{x}{7}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B7%7D%20)
= 18
Fifth, multiply both sides by 7. / Your problem should look like: 42 - x = 126
Sixth, subtract 42 from both sides. / Your problem should look like: -x = 126 - 42
Seventh, simplify 126 - 42 to 84. / Your problem should look like: -x = 84
Eighth, multiply both sides by -1. / Your problem should look like: x = -84
Answer:
x = -84
