Sum of 8n-n^2+12 and 7-n^2-10n

-2n^2-2n+19

Step-by-step explanation:

To find the sum of 8n-n^2+12 and 7-n^2-10n

We collect like terms

-n^2-n^2+8n-10n+12+7

-2n^2-2n+19

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.
