20 PINTS PLEASE HELP! If another equation is graphed so that the system has one solution, which equation could that be?
O y = 2(x+1)
O y = 2(x-1)
O y = 2(x-2)
O y=-2(x+1)

answer: was that a question or answer?

step-by-step explanation:

answer: the anser is 3

step-by-step explanation:

c- 2o is equal to 9

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).
