4: im not sure how to solve this or how to get the answer

5:

Distribute the Negative Sign:

= 3x^2+2x−3+−1(4x^2−8x+23)

= 3x^2+2x+−3+−1(4x^2)+−1(−8x)+(−1)(23)

= 3x^2+2x+−3+−4x^2+8x+−23

Combine Like Terms:

= 3x^2+2x+−3+−4x^2+8x+−23

= (3x^2+−4x^2)+(2x+8x)+(−3+−23)

= −x^2+10x+−26

Answer:

−x^2+10x−26

6: Distribute the Negative Sign:

= −13n^2−3n−6n^4+−1(13n^2+11n−2n^4)

= −13n^2+−3n+−6n^4+−1(13n^2)+−1(11n)+−1(−2n^4)

= −13n^2+−3n+−6n^4+−13n^2+−11n+2n^4

Combine Like Terms:

= −13n^2+−3n+−6n^4+−13n^2+−11n+2n^4

= (−6n^4+2n^4)+(−13n^2+−13n^2)+(−3n+−11n)

= −4n^4+−26n^2+−14n

Answer:

=−4n^4−26n^2−14n

7: and in math means to add

Combine Like Terms:

=4y^3+−8y+−y^3+5

=(4y^3+−y^3)+(−8y)+(5)

=3y^3+−8y+5

Answer:

=3y^3−8y+5

8: Answer choice 3

−5x^2+5x−2

9: answer is −8y

i had this in my notes from a while ago on my laptop so please see the image on how to solve this!

i hope this helps a lot!

HELP PLS GIVING BRAINLIEST
Setler79 [48]

For this case we have by definition, that the equation of a line in the slope-intersection form is given by:

y = mx+b

Where:

m: It's the slope

b: It is the cutoff point with the y axis

We need two points through which the line passes to find the slope:

(0,1)\\(1, -2)

We found the slope:

m = \frac {y2-y1} {x2-x1}\\m = \frac {-2-1} {1-0} = \frac {-3} {1} = - 3

So, the equation is of the form:

y = -3x + b

We substitute a point to find "b":

1 = -3 (0) + b\\1 = b

Finally, the equation is:

y = -3x+1

Option C
