The population in the Northeast was 53,594,378 people in 2000 and 55,317,240 people in 2010. By about what percent did the population change? Did the population grow or shrink? 
 C = 100*(55,317,240 - 53,594,378) / 53,594,378 = 3.2%. This is positive, so the population grew

Determine the value of r so that the line through (5, 2) and (7, r) has a slope of m= -1/2
vodka [1.7K]
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) <=

_____
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)

Write an algebraic expression to represents the verbal expression: the difference between the product of 4 and a number and the
Naily [24]

Answer:

4n-n^2

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:

4n-n^2

Hope this helps.
