Answer:
The Value of b is 23
Step-by-step explanation:
substitute 4 for x, and 3 for y. Then move combine like terms.
3 = -5(4) + b
3 = -20 + b
23 = b
In the table below, x represents miles traveled and y represents the cost to travel by train.
Miles, x
Cost, y
2
8.50
5
15.25
8
22.00
12
31.00
What is the y-intercept of this function?
Answer:
The y-intercept would be 4
Step-by-step explanation:
If I understand this correctly, the points are: (2, 8.50),(5, 15.25), (8, 22), (12, 31)
To find this you first find the slope, which was 2.25.
Then you use a point and do the following, I used (12,31)
1. 31= 2.25(12) + b
2. 31= 27 + b
3. 31 - 27 = 27 - 27 +b
4. 4= b
Referring to the figure, find the unknown
length x. (Do not use a calculator to
approximate your answer. Give the exact answer.)
Some researchers needed to estimate how many catfish were in a local river, so they marked 280 catfish with tags. Later, the researchers trapped 540 catfish, of which 27 had tags. To the nearest whole number, what is the best estimate for the catfish population?
(13 points if solved:)
* Please Answer Properly*
Answer:
793 (ig)
Step-by-step explanation:
so take the 540 and subtract it by 27 then u will get the number of catfishes with no tags, then add the difference with 280 and u'll get the population hope it helps :)
HELP ME WITH MATH!!! So basically I have to figure out how many hours that is between the times.
Answer: (I think its correct)
1: 8 hours and 30 minutes
2: 8 hours
3: 8 hours and 50 minutes
4: 8 hours and 45 minutes
5: 7 hours and 48 minutes
6: 11 hours 13 minutes
7: 11 hours 31 minute
Step-by-step explanation: (Im bad at explaining it)
So I got this by using counting the hours in between the times and taking out the minutes in them,then subtracting the time they took the fall asleep. Every time that has minutes I add that, if it is over 60 minutes I subtract 60 minutes. So like 30+35=65 | 65-60=5.
Lets do a problem: 9:15 (bed) | 10:30(woke up) | 30 minutes (fall asleep)
So we count how many hours in each time and we take out the minutes, so 9:00, 10:00, 11:00, so on and so forth.
So in between the hours its was 13. Then we add the minutes (15+30)
15+30=45. So the answer is 13 hours and 45 minutes, but we got to subtract 13 hours and 45 minutes which is 13 hours and 15 minutes.
Final Answer: 13 hours and 15 minutes.

Here is a math problem...I need help...(I tried it and I couldn't find out the answer
Answer:
y - 6 = x/3 + 17/3 - 6
Step-by-step explanation:
x₁,y₁
A(-5,4)
x₂,y₂
B(1,6)
m = (y₂ - y₁) / (x₂ - x₁)
m = (6 - 4) / (1 - (-5))
m = 2 / (1 + 5)
m = 2/6
m = 1/3
y = mx + b B(1,6)
6 = (1) * 1/3 + b
6 = 1/3 + b
b = 6 - 1/3
b = (18 - 1) / 3
b = 17 / 3
y = x/3 + 17/3
y - 6 = x/3 + 17/3 - 6

help pls?? tysm if you do
Answer:
I believe that the answer you have is correct! Have a nice day!
I might need simple and explanatory answers tho these questions-
if youre able to help, thank you!
Step-by-step (with answer) explanation:
2. You put 15x in the first part and 10 in the second part. Answer is 15x + 10.
You are pretty much multiplying 5 times 3x in the first part of the box and 5 times 2 in the second part of the box.
3. 7x in the first part of the box and -63 in the second part of the box. Ans. 7x - 63.
4. 30x + 45
You are just doing 5 times 6x and 5 times 9 since 5 is outside the parentheses and 6x and 9 are inside it.
5. 12k - 8
6. 9t + 3
7. 4 - 3j
8. 8p + 56 + 16q
9. 12.8d - 40
10. 24c - 2
Negative 12 (from 6 times 2) and positive 10 are added together to make 2 (since it says to combine any like terms.
11. 23b + 42
18b and 5b are added together since they are like terms.
12. 11x + 14
3x and 8x are added together since they are like terms (which makes 11x).

The distance, d, you bike varies directly with the amount of time, t, you bike. Suppose you bike 31.125 miles in 2.5 hours. Write an equation that relates d and t.
Answer:
d=10.8t
Step-by-step explanation:
The distance "d" you bike varies directly with the amount of time "t" you bike.
Therefore d a t
To turn it into a equality , we introduce k, proportionality constant
d=kt
The distance "d" you bike varies directly with the amount of time "t" you bike. Therefore,
d α t
To turn it into equality, we introduce k, proportionality constant.
d = kt
We find the value of k from the given conditions. Suppose you bike 31.125 miles in 2.5 hours.
31.125 = k(2.5)
k = 12.45 miles/hour
Therefore the equation would be:
d = 12.45t
It is a linear graph with a slope of 12.45 and it passes at the origin

a lower starting point.
B. The function shown on the aranh ha
Answer:
I think your answer is A because the starting point and the rate of change for y=5x+5 is 5 and on the graph it looks like the rate of change is 5x and the starting point is -5.
Therefore A is most likely the answer
