Equivalent Expressions When two expressions are equivalent, they always have the same value. These are some examples of expressions. An expression is a mathematical statement that uses numbers, operations, letters, or a combination of all three. 4 8 + 1 d - 7 When two or more expressions are equivalent, they have the same value. 4+2+ 6 and 5+7 are equivalent expressions because they are both equal to 12. 5x and 5.xare also equivalent.

step-by-step explanation:

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.
