What are the steps to find your answer to 3x+4=2x-2

x = -6

Step-by-step explanation:

3x + 4 = 2x - 2

we need to get the x terms on one side and everything else on the other side.And what u do to one side of the equal sign, u have to do to the other side. So start by subtracting 2x from both sides.

3x - 2x + 4 = 2x - 2x - 2combine like terms

x + 4 = -2now we subtract 4 from both sides

x + 4 - 4 = -2 - 4combine like terms

x = -6 <

lets check it...

3x + 4 = 2x - 2when x = -6

3(-6) + 4 = 2(-6) - 2

-18 + 4 = -12 - 2

-14 = -14 (correct)...so it checks out

the value of v.w= -12.

step-by-step explanation:

we are given three vector r,v and w as:

r = < 5, -5, -2> ; v = < 2, -8, -8> ; w = < -2, 6, -5>

we know that r,v and w could also be represented as:

r=5i-5j-2k

v=2i-8j-8k

and w= -2i+6j-5k

where i,j and k are the unit vectors of x,y and z-axis respectively.

also we know that it has the following property:

i.i=1 ; j.j=1; k.k=1

and i.=j.i=i.k=k.i=j.k=k.j=0

i.e. when we multiply two vectors or we find it's dot product we need to only multiply the components of x coordinates with each other; y with each other and z with each other.

hence, v.w= (2i-8j- -2i+6j-5k)

                  = 2×(-2)+(-8)×(6)+(-8)×(-5)

                  = -4-48+40

                  = -12

hence, v.w= -12

i'm sorry mate, but i am not seeing any figures. i am unable to solve this for you.
