A rectangular prism with a volume of 444 cubic units is filled with cubes with side lengths of \dfrac1331start fraction, 1, divided by, 3, end fraction unit. How many \dfrac1331start fraction, 1, divided by, 3, end fraction unit cubes does it take to fill the prism?

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

no i do not : ( what is it?
