Hello from MrBillDoesMath!

Answer:

Your friend is incorrect

Discussion:

| 3x + 8 | -9 = -5 => ( add 9 to both sides)

| 3x + 8 | -9 + 9 = -5 + 9 =>

| 3x + 8 | = 4 =>

3x +8 = 4 or 3x + 8 = -4 =>

x = -4/3 or x = -4

Thank you,

Here is your answer

D. $3×{10}^{3} km$

REASON:

Given equatorial radius= 3,394 km

Rounding it to nearest thousands, we get

$3000 km\\= 3×1000\\= 3×{10}^{3}km$

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
