The solution is n = –2 verified as a solution to the equation 1.4n + 2 = 2n + 3.2. what is the last line of the justification?

 1.4n + 2 = 2n + 3.2

substitute the solution n = -2 into the equation 

 1.4n + 2 = 2n + 3.2

 1.4(-2) + 2 = 2(-2) + 3.2

-2.8 + 2 = -4 + 3.2

-0.8 = - 0.8 

n = -2 makes the equation becomes true

so

Yes, n = -2 is the solution of the equation

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.
