accoding to the web "He started out 25 meters below the edge of the volcano. It takes him 6.25 seconds to reach the edge."
Answer:
25 meters below the edge; 6.25 seconds
Step-by-step explanation:
We can represent this with a linear function in slope-intercept form.
We know the rate of change is 4 since he climbs up at 4 meters per second. We do not know the value of b, the y-intercept.
This gives us
y = 4x + b
We know that he is 13 meters below the edge after 3 seconds. Using -13 for y and 3 for x,
-13 = 4(3) + b
-13 = 12 + b
Subtract 12 from each side:
-13-12 = 12+b-12
-25 = b
This gives us the equation
y = 4x - 25
He started out 25 meters below the edge of the volcano.
To find how long it took him to reach the edge, substitute 0 in for y:
0 = 4x - 25
Add 25 to each side:
0+25 = 4x-25+25
25 = 4x
Divide both sides by 4:
25/4 = 4x/4
6.25 = x
It takes him 6.25 seconds to reach the edge.

Answers
Explanation:
1) domain is all possible x values the graph covers so you can see the arrows point bot direction meaning it will go on forever
2) range is all possible y values so the graph goes all the way up but stops at -4 when going down, but it doesn’t touch 4 so it’s a parenthesis not a bracket (which is used when it’s equal to that number)
3) as x increases in number from negative to positive than y is also increasing (based on the graph)
4) as x decreases it stops a -4 but and doesn’t pass this y value ( it’s finding the limit)
5) x intercept is when y=0
6) y intercept is when x=0

Mrs. Balbas makes a batch of cookies for her math class. Aaron takes 1/6 of the cookies and runs out the door. Matthew then takes 1/5 of the cookies that are left. Paige takes 1/4 of what remains after Matthew leaves. Koji takes 1/3of what remains after Paige, and then Dylan grabs half of the remaining cookies after Koji. Gavin then swoops in and grabs the last remaining 6 cookies. The rest of the class gets nothing and begins to collectively cry. How many cookies were in the batch, to begin with?
Answers
Answer:
36
Step-by-step explanation:
After dylan took half of the cookies and 6 were left there were
12 before he took any
Than If Koji took a 3rd when 12 were left there were 18
Than if Paige took a 1/4 of what was left when there were 18 there were 24
This same pattern is the same for the next 2
24+6 = 30 and than 30+6 = 36
TLDR;
remove 6 per person meaning there were 36 to begin
Mrs. Balbas makes a batch of cookies for her math class. Aaron takes 1/6 of the cookies and runs out the door. Matthew then takes 1/5 of the cookies that are left. Paige takes 1/4 of what remains after Matthew leaves. Koji takes 1/3of what remains after Paige, and then Dylan grabs half of the remaining cookies after Koji. Gavin then swoops in and grabs the last remaining 6 cookies then the batch initially had 432 cookies.
Mrs. Balbas baked a batch of cookies for her math class.
1. Aaron takes 1/6 of the cookies:
If "C" represents the initial number of cookies, Aaron takes (1/6)C cookies, leaving (5/6)C cookies.
2. Matthew takes 1/5 of the remaining cookies:
Matthew takes (1/5)(5/6)C = (1/6)C cookies, leaving (5/6)C - (1/6)C = (2/3)C cookies.
3. Paige takes 1/4 of the remaining cookies:
Paige takes (1/4)(2/3)C = (1/6)C cookies, leaving (2/3)C - (1/6)C = (1/2)C cookies.
4. Koji takes 1/3 of the remaining cookies:
Koji takes (1/3)(1/2)C = (1/6)C cookies, leaving (1/2)C - (1/6)C = (1/3)C cookies.
5. Dylan takes half of the remaining cookies:
Dylan takes (1/2)(1/3)C = (1/6)C cookies, leaving (1/3)C - (1/6)C = (1/6)C cookies.
6. Gavin takes the last 6 cookies:
The remaining (1/6)C - 6 cookies are taken by Gavin.
7. The rest of the class gets nothing, leaving 0 cookies.
Now, let's add up the amounts taken by each student:
- Aaron: (1/6)C
- Matthew: (1/6)C
- Paige: (1/6)C
- Koji: (1/6)C
- Dylan: (1/6)C
- Gavin: 6 cookies
Adding all these together, we get:
(1/6)C + (1/6)C + (1/6)C + (1/6)C + (1/6)C + 6 = (5/6)C + 6
Since the remaining cookies are accounted for,
we know that (5/6)C + 6 = 0, which gives us C = 432.
Therefore, the initial batch had 432 cookies.
