3-(s+4)
less than- subtract
sum- addition
since it said 3 less than the sum of a number and 4 that means you would have to add s and 4
Answer:
y = 5x - 4
Step-by-step explanation:
5 is the slope so it goes in front of the x and -4 is the y Intercept so it goes last.
Answer:First inequality: y >
![\frac{4}{5} x - \frac{1}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B5%7D%20x%20-%20%5Cfrac%7B1%7D%7B5%7D%20)
Second inequality: y < 3 + x
Explanation:The inequality in slope-intercept form has the following general formula:
y < mx + c or y > mx + c (according to the given sign)
where m is the slope and c is the y-intercept
This means that to get any inequality in slope-intercept form, we will have to isolate the y on one side of the inequality.
First given inequality:4x - 5y < 1
4x - 5y + 5y < 1 + 5y
1 + 5y > 4x
1 + 5y - 1 > 4x - 1
5y > 4x - 1
y >
![\frac{4}{5} x - \frac{1}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B5%7D%20x%20-%20%20%5Cfrac%7B1%7D%7B5%7D%20)
comparing this to the general form, we would find that:
slope (m) = 4/5
y-intercept (c) = 1/5
Second given inequality:y - x < 3
y - x + x < 3 + x
y < 3 + x
comparing this to the general form, we would find that:
slope (m) = 1
y-intercept (c) = 3
Hope this helps :)
Answer:
Town C.
Step-by-step explanation:
Average change of population with time for town A = ![\frac{24,500 - 22,000}{4} = \frac{2,500}{4} = 625](https://tex.z-dn.net/?f=%20%5Cfrac%7B24%2C500%20-%2022%2C000%7D%7B4%7D%20%3D%20%5Cfrac%7B2%2C500%7D%7B4%7D%20%3D%20625%20)
Average change of population with time for town B = ![\frac{34,770 - 31,200}{6} = \frac{3,570}{6} = 595](https://tex.z-dn.net/?f=%20%5Cfrac%7B34%2C770%20-%2031%2C200%7D%7B6%7D%20%3D%20%5Cfrac%7B3%2C570%7D%7B6%7D%20%3D%20595%20)
Average change of population with time for town C = ![\frac{22,000 - 18,000}{5} = \frac{4,000}{5} = 800](https://tex.z-dn.net/?f=%20%5Cfrac%7B22%2C000%20-%2018%2C000%7D%7B5%7D%20%3D%20%5Cfrac%7B4%2C000%7D%7B5%7D%20%3D%20800%20)
Average change of population with time for town D = ![\frac{34,100 - 32,000}{3} = \frac{2,100}{3} = 700](https://tex.z-dn.net/?f=%20%5Cfrac%7B34%2C100%20-%2032%2C000%7D%7B3%7D%20%3D%20%5Cfrac%7B2%2C100%7D%7B3%7D%20%3D%20700%20)
Town C had the greatest average change in population over time (800/yr).
The factors of 5 are 1 and 5.
1 x 5 = 5
5 x 1 = 5
