1. Tanner collected 360 cans and bottles while fundraising for his baseball team. This was 40% of what Reggie collected. How man

Inessa05 [86]

1. 360*0.40=144
so they said 40% reggie collected main mor than 40% collected so you need to do add like 360+144=504
the answer 504

2. you need to do new to old
the new is 15 old is 799
799-15=784x100
the high number is 799
so you need to do 799 divided by 100=7.99
now 784 divided by 7.99=98.12
the answer is 98.12

Factor the polynomial function over the complex numbers. f(x)=x^4-x^3-2x−4 Enter your answer in the box. f(x) = The answer is: (

Vladimir79 [104]

Answer:

Factors: $(x+i\sqrt2)(x-i\sqrt2)(x+1)(x-2)=0$

Step-by-step explanation:

We are given a polynomial:

$f(x)=x^4-x^3-2x-4$

We have to factor the given polynomial into its complex factors.

The factorization can be done as follows:

$f(x)=x^4-x^3-2x-4 = 0\\x^4-x^3-2x-4 = 0\\x^4-4-x^3-2x=0\\\text{Identity: }a^2-b^2 = (a+b)(a-b)\\(x^4-4)-(x^3+2x) = 0\\(x^2+2)(x^2-2)-x(x^2+2) = 0\\(x^2+2)(x^2-2-x) = 0\\(x^2+2)(x^2-x-2) = 0\\(x^2+2)(x^2-2x-+x-2) = 0\\(x^2+2)((x(x-2)+1(x-2))=0\\(x^2+2)(x+1)(x-2)=0\\\text{Identity: }a^2-b^2 = (a+b)(a-b)\\(x^2-(\sqrt{-2})^2)(x+1)(x-2)=0\\(x+i\sqrt2)(x-i\sqrt2)(x+1)(x-2)=0$

(2x/3)-(5x/9)-(x/6)-(5x/12)=13/2 this equation is equivalent to:

agasfer [191]

Answer:

-17x=234

Step-by-step explanation:

Given that:

$\dfrac{2x}{3}-\dfrac{5x}{9}-\dfrac{x}{6}-\dfrac{5x}{12}=\dfrac{13}{2}$

$\dfrac{72x-60x -18x-45x }{108} = \dfrac{13}{2}$

$\dfrac{-51x }{108} = \dfrac{13}{2}$

$-102x = 1404$

$-\dfrac{102x}{6} = \dfrac{1404}{6}$

-17x = 234

7. Which of the following best presents the graph of a line with a slope of -2/3 and a y-intercept of -1?

Sonja [21]

The correct graph would be graph A.

Since the line hits the y-axis at -1. And it goes down 2 and to the left 3 for each point.
