Answer:

y =  - 1

Step-by-step explanation:

3y - 2( - 6y) =  - 15

Simplify both sides

3y + 12y =  - 15

Combine Like terms

15y =  - 15

Divide both sides by 15

y =  - 1

Bab needs help with Algebra two homework. show work please! Also I'll give brainliest!
Alekssandra [29.7K]

Answer:

1.  The y values are decreasing by 16  7 and 4 then rising by 7 and 16 so the line of symmetry is at -4 or 4

2. f = g(x) function just like g = f(x) function so say f value table or g(x) function

3.  y = g(x) = -4  when x = 0

4.  y - 0 = - 4x   means the same as y = -4x

5.  [0 , -4] is the vertex

6.  6(5) = 30

next page

7 the y values are increasing by 3/4 , 11/5, 1,  7/1 and  8.5 / 1

which means thy are increasing minimum by 1/1.5 and could be a square function.

8. This is a g function or  a f(x).

9. y intercept is 1

10  common ratio is  0:1

11 equation for the table is  y = x -1

12.  5.400

next page

13.

The values for y are decreasing by 2 then drop by 12 from -2/14 to 0/-2 then increase again at a rate of 20 and decrease slightly to 18 being  -2/-20

we can see this as -2/16 ,-2/14 , 0/-2  2/ -22 meaning the line of symmetry is not clear as we cannot see an average without working out the mean or adding all the totals up.

14.  p(x) function or q value.

15.  the y intercept is -2

16. the equation for this table is y = x-2

17.

The value for p(4) is same method divide smaller into larger then times x 4

-20/-2 = 10  

then -11 x 10 = -110

18. slope = -2

17) if they were asking for value for 4(p) is  16/ -2 = 8 and  -2 / 4  = 0.5/ 8 this shows 8 so 4 is half this value = 0.24 / 4  meaning x = 0.24
