Answer:

Step-by-step explanation:
Givens
- The railing will begin at 36 inches height.
- The slant decreases 9 inches for every 12 horizontal inches.
According to the problem, the slant is

The initial condition of the function is 36, which is a constant. Also, the slant is negative, because the problem states that "decreases".
If we see the problem form the perspective of a linear function, the constant ratio of change would be the slant.
Therefore, the linear function that models this problem is

So, the answer is the first choice.
Answer: the system of equations are
x + y = 22
x + 1.5y = 30
Step-by-step explanation:
Let x represent the number of math problems that Olivia solved.
Let y represent the number of pages that Olivia read.
Olivia completed a total of 22 math problems and pages of reading. This means that
x + y = 22- - - - - - - - - - - - - - -1
Olivia can solve each math problem in 1 minute and she can read each page in 1.5 minutes. Olivia completed a total of 22 math problems and pages of reading in 30 minutes. This means that
x + 1.5y = 30 - -- - - - - - - - - -2
