Solve the two-step equation.

-9x + 0.4 = 4

Which operation must be performed to move all the constants to the right side of the equation?


Then, which operation must be performed to isolate the variable?


The solution to the equation is x =

x = - 0.4

hope this helps!

Hope this helps =)

Let's start b writing down coordinates of all points:

A(0,0,0)

B(0,5,0)

C(3,5,0)

D(3,0,0)

E(3,0,4)

F(0,0,4)

G(0,5,4)

H(3,5,4)

a.) When we reflect over xz plane x and z coordinates stay same, y coordinate  changes to same numerical value but opposite sign. Moving front-back is moving over x-axis, moving left-right is moving over y-axis, moving up-down is moving over z-axis.

A(0,0,0)

Reflecting

A(0,0,0)

B(0,5,0)

Reflecting

B(0,-5,0)

C(3,5,0)

Reflecting

C(3,-5,0)

D(3,0,0)

Reflecting

D(3,0,0)

b.)

A(0,0,0)

Moving

A(-2,-3,1)

B(0,-5,0)

B(-2,-8,1)

C(3,-5,0)

C(1,-8,1)

D(3,0,0)

Moving

D(1,-3,1)
