Answer:

(8, -12)

Step-by-step explanation:

1/2 x -8 + 1/3 x 12 = 0

1/4 x -8 - 1/2 x 12 = -8

<u>1/2 x 8 + 1/3 x -12 = 0</u>

What is the sum of 1 2/5 and 5 3/4​
Art [367]

Answer:

7\frac{3}{20}

Step-by-step explanation:

<em>Hey there!</em>

Well to add this we need to pu it in improper form.

7/5 + 23/4

Now we need to find the LCM.

5 - 5, 10, 15, 20, 25, 30

4 - 4, 8, 12, 16, 20, 24, 28

So the LCD is 20.

Now we need to change the 5 and 4 to 20.

5*4 = 20

7*4 = 28

<u>28/20</u>

4*5=20

23*5=115

<u>115/20</u>

Now we can add 28 and 115,

= 143/20

Simplified

7 3/20

<em>Hope this helps :)</em>

The graph of f(x) = x3 + x2 - 9x - 9 is shown.
AysviL [449]

Answer:

-1, 3, -3

Step-by-step explanation:

I don't see the graph, but you can solve by factoring:

x^3+x^2-9x-9=0\\x^2(x+1)-9(x+1)=0\\(x+1)(x^2-9)=0\\(x+1)(x+3)(x-3)=0

By the factor theorem, the solutions of f(x) are -1, 3, and -3.
