Name coordinates of the vertices of the feasible region.

1) 5> =y> =-3
4x+y< =5
-2x+y< =5
f(x, y)=4x-3y

2) x> =-10
1> =y> =-6
3x+4y< =-8
2y> =x-10
f(x, y)=2x+y

all of the < > are underlined

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
