X is equal to 4 because when you simplify the right side of the equal sign you will get 19. Then when you simplify the left side of the equal sign you will get 4x+3. Next you would want to subtract 3 from both sides giving you 4x=16, which you would then divide by 4 on both sides giving you an answer of x=4
The first thing you should do for this case is to use the following table to perform the equation of a line:
y x
41,431 1995
48,729 2005
We have then that the line that best fits this data is
y = 729.8x - 1E + 06
Then, to know in what year the number of shopping centers reaches 80,000 we must replace this number in the equation of the line and clear x:
80000 = 729.8x - 1E + 06
Clearing x
x = (80000 + 1E + 06) / (729.8) = 1479.857495
nearest whole number
1480
This means that after 1480 years, 80000 shopping centers are reached.
Equivalently, this amount is reached in the year:
1480 + 1995 = 3475
In the year 3475
answer
(a) y = 729.8x - 1E + 06
(b) In the year 3475
Answer: A. -3x+y>-2 and 2y>x+2
Step-by-step explanation: Graph is shown down below.
Hope this helps you out! ☺
(3 * n) +4 = 16
(3 * n) = 12
n = 4
Circumference = 2 π r = 11
r = 11 / 2π = 1.75
Area = π r² = π (1.75)² = 9.625 square units
