$\\ \sf\longmapsto 5x+5+4x-5=180$

$\\ \sf\longmapsto 5x+4x+5-5=180$

$\\ \sf\longmapsto 9x=180$

$\\ \sf\longmapsto x=\dfrac{180}{9}$

$\\ \sf\longmapsto x=20$

y=x=20
z=5x+5=5(20)+5=100+5=105

Which graph represents the solution to the system of inequalities below?

Reika [66]

Answer:

The correct option is;

Step-by-step explanation:

The given system of inequalities are;

5·x - 4·y > 4...(1)

x + y < 2...(2)

Representing both inequalities as a function of "y", gives;

For, 5·x - 4·y > 4...(1), we have;

-4·y > 4 - 5·x

y < 4/(-4) - 5·x/(-4)

∴ y < 5·x/4 - 1

For x + y < 2...(2), we have;

y < 2 - x

Therefore, y is less than the values given by the equation of the straight line equalities, and the feasible region is given by the common region under both dashed lines representing both inequalities as shown in the attached diagram created using Microsoft Excel

The correct option is therefore, B.
