Use a translation rule to describe the translation that is 8 units to the left and 1 unit down 1. (x, y) --> (x + 8, y + 1)
2 .(x, y) --> (x + 1, y + 8)
3. (x, y) --> (x - 8, y - 1)
4. (x, y) --> (x - 1, y - 8)

Step-by-step explanation:

the answer is (x, y) --->(x-8, y-1)

b

step-by-step explanation:

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).
