Let "x" be the total # of students:
Equation:
(1/16)x= 405
x = 16*405 = 6480

Answer:

Part A) The equation in standard form is $75x-y=60$

Part B) The equation in function notation is $f(x)=75x+60$

Part C) The graph in the attached figure

Step-by-step explanation:

Part A)

Let

x -----> the number of days

y ----> the total rent hat Maria has to pay for renting the coat

we have

(3,285) and (6,510)

<u><em>Find the slope of the linear equation</em></u>

$m=(510-285)/(6-3)=75\frac{\$}{day}$

<u><em>Find the equation of the line into point slope form</em></u>

$y-y1=m(x-x1)$

we have

$m=75$

$(x1,y1)=(3,285)$

substitute

$y-285=75(x-3)$ ----> equation of the line into slope point form

<u><em>Find the equation of the line into slope intercept form</em></u>

$y=mx+b$

$y=75x-225+285$

$y=75x+60$ ----> equation of the line into slope intercept form

<u><em>Find the equation of the line into standard form</em></u>

$Ax+By=C$

$y=75x+60$

$75x-y=60$ -----> equation of the line into standard form

Part B) Write the equation obtained in Part A using function notation.

we have

$y=75x+60$

Convert to function notation

Let

f(x)=y

substitute

$f(x)=75x+60$ ---> equation in function notation

Part C) Describe the steps to graph the equation obtained above on the coordinate axes

To graph the linear equation find out the intercepts

<u><em>Find the y-intercept</em></u>

The y-intercept is the value of y when the value of x is equal to zero

For x=0

$y=75(0)+60=60$

The y-intercept is the point (0,60)

<u><em>Find the x-intercept</em></u>

The x-intercept is the value of x when the value of y is equal to zero

For y=0

$0=75x+60$

$x=-60/75=-0.8$

The x-intercept is the point (-0.8,0)

To graph the line plot the intercepts ad join the points

see the attached figure

On the left is a 5-column table with 10 rows titled Religion in North America. The first column is titled Religion with entries Christianity, Unaffiliated, Judaism, Buddhism, Islam, Hinduism, Other Religions, Folk Regions, and Total. The second column is titled 2010 population with entries 266,630,000; 59,040,000; 6,040,000; 3,860,000; 3,480,000; 2,250,000; 2,200,000, 1,020,000; and 344,530,000. The third column is titled percent in 2010 with entries 77.4, 17.1, 1.8, 1.1, 1.0, 0.7, 0.6, 0.3, and 100.0. The fourth column is titled 2050 Projected Population with entries 286,710,000; 111,340,000; 5,920,000; 6,080,000; 10,350,000; 5,850,000; 6,540,000; 2,630,000; and 435,420,000. The fifth column is titled percent in 2050 with entries 65.8, 25.6, 1.4, 1.4, 2.4, 1.3, 1.5, 0.6, and 100.0. On the right is a pie chart titled Religions Practiced in Central America. Christianity is 95.86 percent, Agnostic 2.42 percent, Native Religions 0.99 percent, Atheism 0.15 percent, Spiritism 0.13 percent, and Other is 0.44 percent.
