Answer:

Lets assume this was an slope intercept equation

Step-by-step explanation:

<u>201 = 20k + 204</u>

alright so 1st we have to subtract 204 on both sides which brings us to

201-204 = 20k + 204-204

now our equation looks like this

-3 = 20k now we can divide from both sides

-3/20   20k/20

which brings us to k = -3/20

-2x^2+4x-1 from 6x^2+3x-9
kirza4 [7]

Answer:

8{x}^{2}  - x   - 8

Step-by-step explanation:

We want to subtract

- 2 {x}^{2}  + 4x - 1

from

6 {x}^{2}  + 3x - 9

We set up the subtracttion problem to get:

6 {x}^{2}  + 3x - 9 - ( - 2 {x}^{2}  + 4x - 1)

We expand the parenthesis to get:

6 {x}^{2}  + 3x - 9  + 2 {x}^{2}   - 4x  + 1

Group similar terms:

6 {x}^{2}   + 2 {x}^{2} + 3x- 4x  + 1 - 9

We simplify to get:

8{x}^{2}  - x   - 8
