Line bc has an equation of a line y = 2x + 3, and line ef has an equation of a line y = negative one over 2 x + 4. these two equations represent

Perpendicular lines.

Step-by-step explanation:

We have been given that line BC has an equation of a line and line EF has an equation of a line . We are asked to determine what these both equations represent.

We know that slope of two perpendicular lines is negative reciprocal of each other. This means the product of slope of both lines is equal to .

Let us find the product of slopes of both lines.

Upon cancelling 2 with 2 we will get,

Therefore, the given two equations represent equations of two perpendicular lines.

f(x)=4

step-by-step explanation:

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
