Ineed i just got in trouble for not finishing this class in time and now i’ve been stuck on the same section for weeks i have three problems left i literally can’t handle the stress i just need the answer i just had a panic attack i can’t do this anymore

Step-by-step explanation:

To find a line perpendicular to 2x - 5y = 20, we need to find the slope of the line.  To get the slope, we can solve for y, and get the equation in the form of y=mx + b

So I will solve for y:

So we know the slope is 2/5

The slope of a perpendicular line is the oposite reciprocal of original line.  So the oposite reciprocal of 2/5 is -5/2.  That will be our new slope

Now that we know the slope we can use the point slope formula to find an equation, then solve for y.

y-y₁=m(x-x₁)

y-4 = -5/2(x+ 1/2))

y= -5/2x + 11/4

This is based on simple ratio & scales where a figure on a scale is used to represent the true figure on another scale.

Actual length of bus = 45 ft

The scale drawing is given by;

½ inch to represent 5 ft

Simplifying this fraction gives 45 ft

4½ inches represents 45 ft

Actual length = 45 ft
