Answer:
y = 5x + 3 I just learned this 2 years ago.
Explanation: The y intercept is the beginning of the equation and I'm sure you know y = mx + b, so you take the slope (5) and add x to it, because that is the slope, and add 3 to it because that is y intercept.
Hope it helped!

There are 365 days in a year and 24 hours in a day. An airport camera records for 18 hours and then automatically resets itself to start recording again how many times does the video camera reset itself in a year.
pls help
The answer is 486.6
There are 8,760 hours in a year, so 18 divided by 8,760 would = 486.6
Answer:
Step-by-step explanation:
You could do it this way.
How many hours are there in a year?
365 * 24 = 8760 hours.
This camera does not recognize days. It works on hours. Every 18 hours it resets. So
8760/18 = 486 and 2/3 times.
Obviously it cannot have 2/3 of a day. Normally you would round up, but this time you round down.
The answer is 486 times.
2/3 * 24 = 16
The camera would reset 2 hours into the next day.

A whole number k is greater than 3. Which of the following is true about k/3?
Answer:
D) It is greater than 1.
Step-by-step explanation:
Since k is greater than 3, it could not be between 0 and 1/3 and also could not be between 1/3 and 1
We also know that it is not equal to 1 because it is greater than 3.
Therefore, it is greater than 1.

Step-by-step explanation:
Tina is saving to buy a notebook computer. She has two options. The first option is to put $300 away
initially and save $30 every month. The second option is to put $200 away initially and save $50 every
month. After how many months would Tina save the same amount using either option? How much
would she save with either option?
Plzzz hellpppp
Answer:
After 5 months, she will save the same amount using either option.
She would have saved $450 with either option.
Step-by-step explanation:
Set up expressions to represent the amount of money saved for each saving option, where x is the number of months
The first one can be represented by 30x + 300
The second one can be represented by 50x + 200
Set these equal to each other and solve for x:
30x + 300 = 50x + 200
300 = 20x + 200
100 = 20x
5 = x
So, after 5 months, Tina will save the same amount of money with both options.
To find how much she will save, plug in 5 as x into either expression:
30x + 300
30(5) + 300
150 + 300
= 450
So, she would have saved $450 with either option.
Which fraction is BIGGER?
-7/10 or -4/5
Hello.
Negative numbers closest to 0 are the greatest.
-7/10 is farther away from 0 than -4/5 is.
-7/10 < -4/5, so -4/5 is the bigger fraction.

for each recursive sequences below, find a recursive formula for the general term:
e. 2, 3, 6, 18, 108, 1944, ...
f. 1, 2, 6, 24, ...
i’m not sure how to figure these out! please actually answer and give step by step explanation, i will mark brainliest if correct.
Answer:
e(1) = 2, e(n+1) = e(n-1)*e(n) for n > 1f(1) = 1, f(n) = n*f(n-1) for n > 1Step-by-step explanation:
Given sequences e) 2, 3, 6, 18, 108, 1944, ... f) 1, 2, 6, 24, ...To findRecursive formula for the general termSolutionWe can observe that
e) 2*3 = 6, 3*6= 18, 18*6= 108, 108*18 = 1944f) 1*2 = 2, 2*3= 6, 6*4= 24We can put it in general terms as
e(1) = 2, and e(n+1) = e(n)*e(n-1) for n > 1f(1) = 1, and f(n) = f(n-1)*n for n > 1(b^5)^3 x b^4 simplify
Answer:
b^19
Step-by-step explanation:
In the first factor, we need to use a formula to simplify. The formula is x^a^b = x^(ab). So that means that our first factor simplifies to b^15. Then we add up the powers to simplify it even more. b^15 * b^4 = b^19 using another formula. Therefore b^19 is the answer.
