Y = mx + b
slope(m) = -1/2
(5,2)...x = 5 and y = 2
sub and find b
2 = -1/2(5) + b
2 = -5/2 + b
2 + 5/2 = b
4/2 + 5/2 = b
9/2 = b
so ur equation for this line is : y = -1/2x + 9/2
y = -1/2x + 9/2......(7,r)....when x = 7
y = -1/2(7) + 9/2
y = -7/2 + 9/2
y = 2/2
y = 1
so ur missing variable is 1......ur set of points would then be (7,1) <=
(4 1/2)/(2 2/3) = (9/2)/(8/3)
.. = (9/2)*(3/8) . . . . . . . . . . . . . . the 3rd selection
_____
A mixed number is converted to an improper fraction by
.. a +b/c = (ac +b)/c
Of course, dividing by a fraction is the same as multiplying by its inverse.
.. (a/b) / (c/d) = (a/b) * (d/c)
The sentence that explains how the bonding pattern in metals makes them good conductors of electricity is <u>A. They are willing </u>to give up their valence electrons.
<h3>What are valence electrons?</h3>
Valence electrons are the electrons in the outermost shell, or energy level, of an atom, which participate in the formation of a chemical bond when the outer shell is open.
<h3>Answer Options:</h3>
A. They are willing to give up their valence electrons.
B. Their nucleus has more protons than neutrons.
C. They are malleable.
D. They have a simpler electron arrangement.
Thus, the sentence that explains how the bonding pattern in metals makes them good conductors of electricity is <u>Option</u> A.

Answer:
Step-by-step explanation:
I use 'n' as the unknown value, but you can use any letter you want as the variable.
The product of four and a number would be represented by '4 * n'. The ideal way to write this would be '4n', even though '4 * n' is also correct in value.
The square of the number would be n². Squaring a number is multiplying a number by itself.
The phrase 'difference between...' means subtraction.
Putting it together:
"The difference between the product of 4 and a number and the square of the number" would be:
Hope this helps.
