Please help me, thanks.
How do you have the patience to write all of that 😳😳😳
correct, it is an arithmetic sequency, with the distance between numbers 10
Correct, the pattern is adding 10's each time, therefor like bobpursley said, it an arithmetic sequence.
its C. promiss me
It’s c

Lol yea
why tho
Why tho what?
wuh?
I'll give the correct answers when I'm done
1. 39, 49, 59
2. 2,038 bulbs
3. -5,-3,1,7
4. the first graph one ( speed:20 Time:15 )
5. The speed of the car decreases from 4 mi/h to 2 mi/h in the first 3 seconds, increases to 5 mi/h in the next 2 seconds, and then remains at 5 mi/h for the last 5 seconds.
6. 24
7. E(m) = 12m
8. 2/3 NOT negative
9. Dixie Hill; it rises 3/5 foot for every 1 foot of horizontal travel
10. its ________________

or if you can't understand that it is the first one but it could change.
11. ________________

--------------------\---------
or again unless it changed
12. y = 6 + 3x
13. y =4.50x + 5.00
14. y = 0.95(x - 1 ) + 1.15
15. y= -3x - 8
16. y = x^2 + 5
And the rest are essays ^^

A number of points are shown on a graph. The points are connected by line segments.The y-axis is labeled Speed left-parenthesis miles per hour right-parenthesis and is numbered from 0 to 60 with a step size of 10. The x-axis is labeled Time left-parenthesis s right-parenthesis and is numbered from 0 to 15 with a step size of 5. The line segments connect these approximate points: left-parenthesis 0 comma 22 right-parenthesis and go through approximately left-parenthesis 5 comma 22 right-parenthesis, left-parenthesis 10 comma 46 right-parenthesis, and left-parenthesis 15 comma 46 right-parenthesis.
