First you divide everything by 4 which will become b^2+2b-3=0
Then you can factor this which is
(b-1)(b+3)=0
B=1
B=-3 ... I think that's how you do it

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

the number of points in the first five games of the football season are listed below. what is the mean number of points scored?
yarga [219]
^ You again? Quit being sus and answer the question here instead of elsewhere.

To find the mean, all you have to do is add each number and then divide by how many numbers you added.

So, 38 + 29 + 16 + 42 + 33 = 158. There were five numbers added, so the next step is to divide 158 by 5. That equals 31.6 as your answer.

What are two contributions to math that Leonardo Fibonacci made
jekas [21]
Fibonacci is famous for his contributions to number theory.

In his book, Liber abaci he introduce the Hindu-Arabic place-valued decimal systems and the use of Arabic Numerals  into Europe.He introduced the bar we use in fractions, previous to this, the numerator has quotations around it. The square root notation is also is Fibonacci method.
