They are both straight lines? Sorry if thats not what you wanted or if its wrong
You need to get x by itself. So add 11 to both sides. Then you get 9x>4x+23. Subtract 4x from both sides. The new inequality you get is 5x>23. Then, divide each side by 5. You get x>4.6. The answer is x>4.6. Hope this helps! ;)
Answer:
Per child admission costs $8.5
Per Adult admission costs $13.5
Step-by-step explanation:
Let x be the amount of admission per child and y be the amount of admission per adult
For Tom's party:
13x+2y=137.50 (Equation 1)
For Lisa's Party:
9x+2y=105.50 (Equation 2)
Using Elimination Method:
Add Equation 1 & 2
13x+2y=137.50
9x+2y=105.50
- - = - (Change of Signs)
---------------------------------
4x+0y=34.00
x=34/4
x=8.5
Putting the value of x in Equation 2
13(8.5)+2y=137.50
110.5+2y=137.50
2y=137.50-110.50
2y=27
y=27/2
y=13.5
The ratios that have the same constant of proportionality as Ada's observation 15/9, 30/18
According to the question:
- We are required to select all the ratios that have the same constant of proportionality as Ada's observation.
let y and x represent amount of juice and oranges respectively;
k = 5/3
The ratios equivalent to the constant of proportionality is 15/9, 30/18

Answer:
The second choice, 
.
Step-by-step explanation:
Note, that the expression 
is an equation. A point 
is on the graph of 
if and only if the value of 
and 
satisfy this equation; that is: in other words, the 
-coordinate of that point (the second number in the tuple) should be equal to 
, which is equal to 
(evaluated where 
is equal to the first number in the tuple.
For each tuple in the choices, calculate the value of where is equal to the first number of each tuple. Compare the result to the second number in that tuple. That choice corresponds to a valid point on only if these two numbers match.
- First choice:
, 
. That's not the same as the second number, 
. Therefore, this point isn't on the graph of . - Second choice:
, 
. That matches the second number in the tuple. Therefore, this point is on the graph of . - Third choice:
, 
. That's not the same as the second number, 
. Therefore, this point isn't on the graph of . - Fourth choice:
, 
. That's not the same as the second number, 
. Therefore, this point isn't on the graph of .
