How come two negatives make a positive, but three negatives makes a negative? Does this have to do with there being an odd/even amounts of negatives and cancelling each other out?

Answers

Okay well work step by step. If there is three negatives, you first want to multiply the first two negatives. Your number will come out positive but you are still left with one more negative. so you will multiply the positive number with the negative number which comes out with a negative number.

Identify the a,h,k and vertex for each quadratic function

Answers

9514 1404 393

Answer:

  a = -2, h = -3, k = -1

  vertex = (-3, -1)

Step-by-step explanation:

Compare the given equation ...

  g(x) = -2(x +3)² -1

to the vertex form ...

  g(x) = a(x -h)² +k

You see that ...

  a = -2

  -h = +3  ⇒  h = -3

  +k = -1  ⇒  k = -1

The vertex is (h, k), so is ...

  vertex = (-3, -1)

Answer:

The slope of the line = m = 3

Step-by-step explanation:

Given the table

x           3          6            8           12

y           7          16          22          34

Taking any two points let say (3, 7) and (6, 16)

(x₁, y₁) = (3, 7) (x₂, y₂) = (6, 16)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]  

                 =  [16 - 7] / [6 - 3]

                  = 9 / 3

                 = 3

Therefore, the slope of the line = m = 3
