Julie has a jelwery box shaped like a cube. The volume of the jelwelry box is v cubic inches. Write an expression that represents the edge length of julies jelwery box in inches

Edge length in inches = 3√(v in³)

Step-by-step explanation:

A jewelry box is shaped like a cube, with it's volume as v cubic inches.

The formula for the volume of a cube = (edge length)³

From the question, we are asked to write an expression that represents the edge length of julies jelwery box in inches

volume of a cube = (edge length)³

v in³ = edge length ³

We cube root both side

= 3√(v in³) = 3√(edge length³)

Edge length = 3√(v in³)

Therefore, the expression that represents the edge length of julies jelwery box in inches is:

Edge length in inches = 3√(v in³)

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3
