Let x be a time in hours and y be an amount of remaining entries. You have that:
- At start Ariel wants to write 8 entries for her blog. This means that x=0 and y=8 (0 entries were written). The point with coordinates (0,8) belongs to needed graph.
- After 2 hours, she has 5 entries left. This gives you that at x=2, y=5 and graph passes through the point (2,5).
- After 4 hours, she has 2 entries left. This gives you that at x=4, y=2 and graph passes through the point (4,2).
Find the slope of the line that is passing through the points and by formula
Thus, the slope is
Answer: graph of line going through (0, 8) with a slope of -1.5
If you would like to know if Miles is going to spend more or fewer hours bicycling this week than last week, you can calculate this using the following steps:
2/3 as many hours:
2/3 * x hours
Because 2/3 is less than 3/3 = 1, this means that Miles is going to spend fewer hours bicycling this week than last week.
Answer:
48 students on each team. 3 substitutes

First I did 243 divided by 5. I got 48 r3. Therefore 48 students are on each team and there are 3 substitutes
Answer:
676 beams
Step-by-step explanation:
assuming y = beams left and x = floors built
y = 700-24x1
y = 700-24
y= 676
Answer:
Hello your question has some missing information below is the complete question
answer :
Step-by-step explanation:
Red car and Blue car take up 2 spaces each
Green cars take up 1 space
<u>lets determine the number of ways of filling up the parking spaces</u>
i) First lets assume the last space is filled by Green car then there will be space occupied hence there will be ( n - 1 ) spaces left to be filled in ways
ii) lets assume the last space is filled by either a Red car or a Blue car then there will be parking space occupied hence there will be
( n - 2 ) spaces left to be filled in ways
<u>Hence A closed formula for </u><u> </u>
where : a1 = 1 way , a2 = 3 ways
