Identify the pair of lines as parallel or perpendicular.
1. f(x) = 2x + 3
g(x) = -1/2x + 3

2. f(x) = 1/3x + 4
g(x) = 1/3x + 5

1.  Perpendicular

2.  Parallel

Step-by-step explanation:

A line is parallel to another if it has the same slope

A line is perpendicular to another if it has the opposite reciprocal of the other slope.

1.  f(x) = 2x + 3

   f(xx) = -1/2 + 3

Perpendicular

2.  f(x) = 1/3x + 4

    g(x) = 1/3x + 5

Parallel

Step-by-step explanation:

i can't solve unless i know what the line is

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).
