what techniques are similar when solving linear equations and linear inequalities, yet different?

Answer 1

what you do to one said, you do to the other

but when you divide or multiply by a negative number you flip over the sign

so if it was > before, and you divide by -20.. then it's >

pretty easy concept, still the same technique

Answer 2

commonly, the linear equation defines the features of the boundary of the area defined with the aid of the linear inequality. x = 0 is a linear equation defining a vertical line with the aid of the inspiration in R2. x > 0 is a linear inequality defining the right-1/2 airplane in R2. the line x=0 defines the boundary of the area x > 0.

Answer 3

same:

solve both of them lik there is a = sign there

difference:

if u have to multiply or divide by a negative # on the inequality then the inequality sign flips (< turns to > ; > turns to <)

when graphing them u use:
- a solid line for equalities
- a dotted line and shading* for inequality
- a solid line and shading* for greater than or equal to/ less than or equal to

* shading is above or below ur line depending on if the sign says < or > ...... if it has < then shade below the enitre line, if it has > then shade above than entire line
