Answer: The system consists of parallel lines

Step-by-step explanation:

Given system of lines :

$y=\dfrac13x-4$

$3y-x=-7$

Substitute $y=\dfrac13x-4$ in $3y-x=-7$ , we get

$3(\dfrac13x-4)-x=-7\\\\\Rightarrow\ x-12-x=-7\\\\\Rightarrow\ -12=-7$ , which is not true.

That means , system has no solution.

i.e. they are representing parallel lines. [Parallel lines do not intersect and hence they do not have solution.]

Safe wheelchair ramp specifications require about 4.75° maximum angle to be constructed with the ground. At a particular buildin

NeTakaya

Answer:

The ramp must cover a horizontal distance of approximately 19.081 feet.

Step-by-step explanation:

Given the vertical distance ( $y$ ), measured in feet, and the angle of the wheelchair ramp ( $\theta$ ), measured in sexagesimal degrees. The horizontal distance needed for the ramp ( $x$ ), measured in feet, is estimated by the following trigonometrical expression:
