anonymous
  • anonymous
yes or no ?
anonymous

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
  • anonymous
\[y=x^5\]
anonymous
  • anonymous
do u mean that, this is not the answer
anonymous
  • anonymous
\[y=5^x\]
anonymous
  • anonymous
thats the answer
anonymous
  • anonymous
|dw:1360197550435:dw|yes I have these as my answers.

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

look u have to know how to work this out
anonymous
  • anonymous
-7-(-12)=5
anonymous
  • anonymous
how old are u? which year
anonymous
  • 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
  • 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
  • anonymous
no don't send the graph
anonymous
  • anonymous
ok
anonymous
  • anonymous
why dont you want me to send the graph?
anonymous
  • anonymous
the graph will be V
anonymous
  • anonymous
because i can figure the graphs in my head
anonymous
  • anonymous
as u can see this is like y=x and y=-x
anonymous
  • anonymous
yes
anonymous
  • anonymous
next
anonymous
  • anonymous
I don't know which graph it is though....There are 2 that are going up.
anonymous
  • anonymous
ok send the graph

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