these drawing right here are for the solve question I put up.

- anonymous

for the absolute value question

- anonymous

\[\left| x-\frac{ 1 }{ 5 } \right|=2\]

- anonymous

the answers are

- anonymous

11/5 , -9/5

- anonymous

it doesn't have that as a option.

- anonymous

oh that is =3 not 2 sorry

I think I got this. I picked the 2nd graph.

- anonymous

Hey mathminds. When you get back on we have to go really fast through this test becasue I have on;y a few hours to complete the rest of this. and i have to get it done!!

24. The table shows the relationship between two variables. Is the relationship a linear function?

- anonymous

back sorry that was one of my students

- anonymous

|dw:1360196848549:dw|

- anonymous

yes or no ?

- anonymous

its the 2nd graph

- anonymous

that's what I picked. Do you know whether that tableI showed you is linear or not?

- anonymous

which question 25

- anonymous

no 24.

- anonymous

do you know which one I'm talking about ?

- anonymous

ok let me see

- anonymous

ok

- anonymous

yes it is

25. The ordered pairs (1, 5), (2, 25), (3, 125), (4, 625), and (5, 3125) represent a function. What is a rule that represents this function? (1 point)y = x5
y = 5x
y = 5x
y = x + 5

- anonymous

\[y=x^5\]

- anonymous

do u mean that, this is not the answer

- anonymous

\[y=5^x\]

- anonymous

thats the answer

- anonymous

|dw:1360197550435:dw|yes I have these as my answers.

- anonymous

y=5^x

- anonymous

its the first one

26. Suppose noodle soup is on sale for $0.75 a can and you have a coupon for $0.50 off your total purchase. Write a function rule for the cost of n cans of soup. (1 point)C(n) = 0.75n – 0.5
C(n) = 0.5n – 0.75
C(n) = (0.75 + n) – 0.5
C(n) = (0.5 + n) – 0.75

- anonymous

when x=1 , 5^1=5 ->(1,5)...

- anonymous

huh??

- anonymous

first one

28. Tell whether the sequence is arithmetic. If it is, what is the common difference?
–12, –7, –2, 3, . . . (1 point)yes; 5
yes; 8
yes; 3
no

- anonymous

0.75n-0.5

5

- anonymous

look u have to know how to work this out

- anonymous

-7-(-12)=5

- anonymous

how old are u? which year

- anonymous

I understand how to work out that equation I just have a hard time figuring out how to put it into a equation. and I'm 15. 9th grade.

- anonymous

I have to send a graph with this problem.
29. What is the graph of the function rule?
y= |2 x | + 1 (1 point)

- anonymous

no don't send the graph

- anonymous

ok

- anonymous

why dont you want me to send the graph?

- anonymous

the graph will be V

- anonymous

because i can figure the graphs in my head

- anonymous

as u can see this is like y=x and y=-x

- anonymous

yes

- anonymous

next

- anonymous

I don't know which graph it is though....There are 2 that are going up.

- anonymous

ok send the graph

Yeah I'm definitley gonna do that. This is very frustrating when I wait at the last minute and I don't know how to do anything :(

- anonymous

never get to that habit, u have to get rid of it now and thats an order ok

- anonymous

ok

- anonymous

when u add +1 it shifts up by 1 unit in y axes

- anonymous

Okay it's very hard for me to understand stuff through typing and texting so is the answer the first graph? cause I think it is.

- anonymous

yup

- anonymous

yayyyyyyyy!

30. For the data in the table, does y vary directly with x? If it does, write an equation for the direct variation.
x y
3 6
6 18
8 24
(1 point)yes; y = 2x
yes; y = 3x
yes; y = 4x
no; y does not vary directly with x
heres the table.|dw:1360198952296:dw|
