Use the distributive property to expand the following expression. -2(2.1x + 3y - 1.8)

-2 ( 2.1 x +3 y - 1.8 = - 4.2 x -6 y + 3.6

Step-by-step explanation:

Distributive property:-

distributive law

let a , b, c are two real numbers and by using distributive law is

a.(b+c) = a.b + a.c

given -2 ( 2.1 x +3 y - 1.8) = -2 . (2.1)x + (-2).3 y + (-2).(-1.8)

now simplification right hand side

         -2 ( 2.1 x +3 y - 1.8   = - 4.2 x -6 y + 3.6

b. hoped i'm right lol

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.
