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

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
