Answer:

Step-by-step explanation:

Salary offered to Emily after college = $35000

Rise in her salary = $2000 every year

Let she works for x years in the company,

Salary rise in her salary = $2000x

Total salary after x years = $(35000 + 2000x)

The independent variable x represents NUMBER OF YEARS and dependent variable is the TOTAL SALARY,because the SALARY depends on the NUMBER OF YEARS WORKED.

A function these variables is C(x) = 35000 + 2000x

So, C(4) = 35000 + 2000(4) = 43000, meaning 4 years later Emily will earn a salary $43000.

Direct variation is:

$\sf y=kx$

Where 'k' is the constant of variation. Let's plug in y = -6 and x = 10 into the formula:

$\sf -6=k(10)$

Divide 10 to both sides:

$\sf k=-\dfrac{3}{5}$

Plug this in for 'k' in our formula:

$\sf y=-\dfrac{3}{5}x$

This is our formula. To find out what 'y' is when 'x' = 5, plug in 5 for 'x':

$\sf y=-\dfrac{3}{5}(5)$

Multiply:

$\boxed{\sf y=-3}$

9.

Let's plug in y = 9 and x = 8 into our formula:

$\sf 9=k(8)$

Divide 8 to both sides:

$\sf k=\dfrac{9}{8}$

So our equation is:

$\sf y=\dfrac{9}{8}x$

Now let's plug in 18 for 'y' to find out what 'x' is when y = 18:

$\sf 18=\dfrac{9}{8}x$

Divide 9/8 to both sides or multiply by its reciprocal 8/9:

$\sf x=18\cdot\dfrac{8}{9}\rightarrow \boxed{\sf 16}$

A person drove 36 miles per hour on a trip. If he had driven 48 miles per hour he would have arrived 4 hours earlier. What was t

nlexa [21]

Answer:

d = 576

Step-by-step explanation

Think of the two different speeds as belonging to 2 different cars going to the same place, taking the same route and going to the same place.

Let the time traveled by the fast car = t

Let the time traveled by the slower car = t+4

Let the rate of travel of the slow car = 36 mph

Let the rate of travel of the fast car = 48 mph

===========

d = 36*(t + 4)

d = 48 * t

Since the distance is the same, they can be equated.

48t = 36(t + 4) Remove the brackets.

48t = 36t + 144 Subtract 36t from both sides.

48t - 36t = 144 Combine

12t = 144 Divide by 12

t = 144/12

t = 12

Therefore the faster car takes 12 hours to get where it is going.

d = 48 * t

d = 48 * 12

d = 576
