L= {0, 20, 40, 80, 100}
m = {5, 10, 15, 20, 25}
n = {10, 20, 30, 40, 50}
sets l, m, and n are shown above. which of the
following sets represents lu(mnn) (the union of l
with the intersection of sets m and n)?

i agree because i see the other persons thinking is clear

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.
