Answer: See Explanation

Step-by-step explanation:

You didn't really say what you want to calculate but based on the information, I'll assume that you want to calculate the total cost.

Since he expression 4(a+12)+5(8) represents the total cost of the tickets. Therefore, the total cost will be:

= 4(a+12)+5(8)

= 4a + 48 + 40

= 4a + 88

The tuition is an illustration of a linear function.

The cost of tuition and fees in the academic year 2023-2024, is $12260

Let the number of academic years after 2014-2015 academic year be x.

So, we have:

\mathbf{(x,y) \to (0,9200)(5,10900)}

A linear function is represented as:

\mathbf{y = mx + b}

Where m represents the slope (i.e. constant rate), and b represents the y-intercept (i.e. the value of y when x = 0)

So, we have:

\mathbf{10900 = 5m + 9200}

Subtract 9200 from both sides

\mathbf{1700 = 5m}

Divide both sides by 5

\mathbf{340 = m}

So, we have:

\mathbf{m =340 }

The function becomes

\mathbf{y = mx + b}

\mathbf{y = 340x + 9200}

In the academic year 2023-2024, x = 9.

So, we have:

\mathbf{y = 340x + 9200}

\mathbf{y = 340 \times 9 + 9200}

\mathbf{y = 3060 + 9200}

\mathbf{y = 12260}

Hence, the cost of tuition and fees is $12260

jason runs 440 yards in 75 seconds. At this rate, how many minutes does it take him to run a mile? (1 mile = 1,760 yards).​
mamaluj [8]

Answer:

5 minutes

Step-by-step explanation:

we know that

Jason runs 440 yards in 75 seconds

using proportion

Find out how many minutes does it take him to run a 1.760 yards (one mile)

\frac{440}{75}=\frac{1,760}{x}\\\\x=1,760(75)/440\\\\x= 300\ sec

Convert seconds to  minutes

Divide by 60

300\ sec=300/60=5\  min

These tables represent a quadratic function with a vertex at (0, -1). What is
Bond [772]

Answer:

B

Step-by-step explanation:

We can notice that based on the given pattern, the average rate of change from x=n to x=n+1, where n \in \mathbb{Z}, is -2n-1.

So, the average rate of change from x=8 to x=9 is -2(8)-1=-17.
