Answer:
30:1
Step-by-step explanation:
1. Look at the graph and follow along the lines.
2. When x is 1 in hours then cakes are 30.
3. So we can write the ratio from cakes to hours.
4. The ratio is 30:1.
Answer:
y = - 5x - 1
Step-by-step explanation:
The first thing to do (always) is pay attention to x =0. That at least gives you a partial answer. y = y' - 1. when you put 0 in for whatever y' is you get 0. What about the other numbers? How did they come about.
We have another clue. Whenever you put in a positive number for x, you get a negative answer for y. That's interesting. So y' has a minus sign associated with it.
y = -ax - 1 Make a>0 so there is only 1 minus sign. x cannot have an even power, because an even power would make everything positive except the -1.
So we'll start with y= - ax - 1 We'll also make the assumption that a = 1
y = - x - 1 That won't work. a >1 otherwise x = 2 won't give - 11
y = -ax - 1
let x = 2
let y = - 11 Solve for a
y = - ax - 1
- 11 = -a*-2 - 1 add 1 to both sides
-11 + 1 = - a(-2) - 1 + 1
- 10 = -2a Divide by - 2
- 10/-2 = -2a/-2
a = 5
Answer: y = - 5x - 1
6n+5, because you just subtract 9n with 3n
I am sorry but this cannot be put as a mixed number. The answer is 11. To dot his do 11/3 divided by 2/6 u would first do same change flip and do 11/3 times 6/2 which then u would multiply straight across and u would get 66/6 which equals 11 because 66 divided by 6 equals 11. I hope this helped u! ;)
52=100%
x=30%
52/x=100%/30%
which equals to 15.6
Answer 15.6
