12) Linear function.
13) Linear function.
14) Non-linear function.
Step-by-step explanation:
First we define Linear and non-linear functions.
The Equation of linear function has no exponent having degree greater than 1, and the graph of linear function is a straight line
The Equation of non-linear function has exponent having degree greater than 1, and the graph of linear function is a curved line.
12) 2x+3y=7
This equation satisfies the definition of linear function, so it is linear function.
13) y+x=4x+5
This equation satisfies the definition of linear function, so it is linear function.
14) 
This equation satisfies the definition of non-linear function, so it is non-linear function.

Answer:
Ratio is 236 : 241
Step-by-step explanation:
Lake County’s smallest forest preserve is 472 acres. Orange County’s smallest preserve is 482 acres
Lake County’s smallest forest = 472
Orange County’s smallest = 482
To find ratio we make a fraction
Ratio = Lake County’s forest / Orange County’s forest
= 
Now simplify the fraction
divide top and bottom by 2
Ratio is 236 : 241
Answer:
D. 23/27
Step-by-step explanation:
The good news is, they wrote out all the possible options for you.
There are 27 possibilities in all, so that's our denominator.
They want to know which possibilities have a W in there OR an R comes first. So we'll count up the possibilities that start with R. There are 9.
Then, of the remaining 18, 14 include a W somewhere in there.
9 + 14 = 23 out of 27.
We are not counting the Ws in the possibilities that start with R, because of the OR in the sentence.

Answer: 12 stars
Step-by-step explanation:
First find out the number of stars he gained by scoring goals:
= Number of goals scored * Stars if goal is scored
= 5 * 3
= 15 stars
Then find out the number of stars he is to lose by missing the goal:
= No. of goals missed * stars if goal missed
= 4 * 3/4 stars
= 3 stars
The total number of stars he has are:
= Stars gained - Stars lost
= 15 - 3
= 12 stars
