For a school band fundraiser, students are selling seat cushions for $4 each and license plate holders for $6 each. One student raises $304. Write an equation in standard form of the line that models the possible combinations of seat cushions and license plate holders the student sold. List two of these possible combinations. Write an equation of the line that passes through the point (4, 7) and is (a) parallel to and (b) perpendicular to the line y =x- 1.

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
