Answer:
191
Step-by-step explanation:
An = a1 + (n-1)d
An = 5 + (63-1)3 = 191
Club Members = $25 + $7 per movie(x)
No membership club = $12 per movie(x)
We need to know how many movies must each purchase to equal in costs.
Set up both equations to equal each other and solve for x=movies.
25 + 7x= 12x
25 + 7x -7x = 12x - 7x
25= 5x
25/5=5x/5
5=x it will take them both 5 movies each to have equal costs.
Answer:
y=-3x-2
Step-by-step explanation:
step 1- find the slope
parallel to means same slope, so look at y+3x=4, its not in the correct slope form so we subtract both sides by 3x to get y=-3x+4, the slope is the coefficient of x which is -3. Slope equals 3
step 2- use the point slope form which is y-y1=m(x-x1)
and substitute in the numbers (only substitute y1,x1, and m)
m is the slope which we found to equal -3
x1 and y1 are the points that they gave us (-2,4) are (x1,y1)
x1=-2
y1=4
step 3- substitute
y-y1=m(x-x1)
y-4=-3(x-(-2))
simplifies to y-4=-3x-6
add 4 to both sides to get y=-3x-2
0.84(20)=$16.80
700/100=7
7(1.02)=$7.14
$7.14+16.80=$23.94 in total
Answer: 19 people per sqaure mile
Step-by-step explanation:
Given : Population in 2000 = 103,970,000
The population increased by 13.4% in 2010.
Population in 2010 = 103,970,000 + 13.4% of (103,970,000)
= 103,970,000+ (0.134)(103,970,000)
= 103,970,000(1+0.134)
=103,970,000(1.134)
=117,901,980
In 2000,
Population density= 
In 2010
Population density =
Difference = 155-136 = 19 people per sqaure mile
Hence, the increase in population density in 2010 = 19 people per sqaure mile
