It is found that the number of married and single adults in a certain town are subject to the following statistics. suppose that x and y denote the number of married and single adults, respectively, in a given year (say as of january 1) and let m and s denote the corresponding numbers for the following year. complete parts a through d. 0.6xplus0.4yequalsm 0.1xplus0.9yequalss (a) write this system of equations in matrix form. nothing[start 2 by 1 matrix 1st row 1st column x 2nd row 1st column y endmatrix ]equals[start 2 by 1 matrix 1st row 1st column m 2nd row 1st column s endmatrix ]

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

step-by-step explanation:

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
