Help!! <br><br> I think I got these wrong, so please help!! Thank you!
Andrew [12]

Answer:

(x+3)(x+4)(x-4)

x+2 and x-3 are not factors but x-4 is

Step-by-step explanation:

let's factor it :)

x^3 + 3x^2 - 16x -48

first we will factor this:

x^3 + 3x^2

x^2(x + 3)

then factor the second part :

- 16x - 48

-16(x + 3)

so now,

x^2(x + 3) - 16(x + 3)

factor out x+3

(x+3)(x^2 - 16)

factor x^2 - 16

(x+3)(x+4)(x-4)

If y varies directly with x and y =70 when x=14, find x when when y = 110
olganol [36]

x ∝ y  

 

x

-- = c

y  

 

x = yc

14 = 70c

c = 1/5

 

x = 1/5*110

= 22

The cart says x: 9 4 5 6 and y : 5 0 1 2 and it's set up like this a. Y =x-4 B. y=x+1 C.y=x+6 D. Y=2x +4
emmasim [6.3K]

I am assuming that the question is asking for the equation of the line if it goes through those coordinates. In which case, the answer would be A. y = x - 4

We can see this because if we substitute in any of the x and y values, the equation is correct:

5 = 9 - 4

0 = 4 - 4

1 = 5 - 4

I hope this helps!

            -----------
           2 + 6 = 8
44/8 = 5.5
