Answer: -1 + or - root5

Step-by-step explanation:

The other zeros of function m(x) = x^3 + 3x^2 - 2x - 4 are x = 2, x = -2

To find the zero of a function f(x), we need to find the value of f(0).

"A trinomial is a polynomial consisting of three terms."

For given question,

Given function : m(x) = x^(3) + 3x^(2) - 2x - 4

We need to find the zeros of a function.

to find the value of x for which m(x) = 0

x^(3) + 3x^(2) - 2x - 4 = 0

We know, x = -1 is a zero of given function.

So, (x + 1) is the factor of given trinomial x^(3) + 3x^(2) - 2x - 4 = 0.

To factorize above trinomial we divide it by x + 1.

Using synthetic division,

m(x)/(x + 1)

= (x^(3) + 3x^(2) - 2x - 4)/(x + 1)

= x^(2) + 2x - 4

So, x^(3) + 3x^(2) - 2x - 4 = (x + 1)(x^(2) + 2x - 4)

Now, to find other zeros of a function we solve the quadratic equation x^(2) + 2x - 4 = 0

⇒ x^(2) + 4x - 2x - 4 = 0

⇒ x(x + 2) - 2(x + 2) = 0

⇒ (x + 2)(x - 2) = 0

⇒ x + 2 = 0 or x - 2 = 0

⇒ x = -2 or x = 2

This means, x = -2 and x = 2 are other zeros of a function.

Answer:

x = 80

Step-by-step explanation:

cuz 1 side is 50, the other side has gotta be 50 too. 50 + 50 = 100, if the sum of all angles in a triangle is 180, then 180-100=80. Therefore, the remaining degrees is 80 and that's x.

Answer:

y=14

Step-by-step explanation:

8y-(8+6y)=20

8y - 8 - 6y = 20

2y - 8 = 20

2y = 20 + 8

2y = 28

y = 14

Answer:

Shelf A = $6 ;Shelf y = $4

Step-by-step explanation:

Let :

x = cost of items from shelf A

y = cost of items from shelf B

3x + 2y = 26 - - - - (1)

2x + 5y = 32 - - - - (11)

Using elimination method :

Multiply (1) by 2 and (11) by 3

6x + 4y = 52 - - - (111)

6x + 15y = 96 - - - (1V)

Subtract (1V) from (111)

-11y = - 44

y = 44/ 11 ; y = 4

Put y = 4 in (1)

3x + 2(4) = 26

3x + 8 = 26

3x = 26 - 8

3x = 18

x = 18 / 3

x = 6

You can use those variables specified to make symbolic relation between the cost and number of items. Then you can use any of the methods to solve the obtained system of equations.

The cost of items from shelf A is x = $6

The cost of items from shelf B is y = $4

Given that:

x represents the cost of an item from shelf A

y represents the cost of an item from shelf B

From given data, we have:

[tex]3 \times x + 2 \times y = \$26\\ 2 \times x + 5 \times y = \$32[/tex]

Or, we get the system of equations as:

[tex]3x + 2y =26\\ 2x + 5y = 32[/tex]

[tex]3x + 2y = 26\\ 2y = 26 - 3x\\ y = \dfrac{26-3x}{2} = 13 - 1.5x[/tex]

Substituting this value of y in second equation, we get:

[tex]2x + 5y = 32\\ 2x + 5(13-1.5x) = 32\\ 2x - 7.5x + 65 = 32\\ -5.5x = -65 + 32\\ 5.5x = 33\\\\ x = \dfrac{33}{5.5}\\\\ x = 6[/tex]

Using this value of x, we get:

[tex]y = 13 - 1.5x\\ y =13 - 1.5 \times 6\\ y = 13 - 9 = 4[/tex]

Thus, we have:

The cost of items from shelf A is x = $6

The cost of items from shelf B is y = $4

Answer:

R (Q) = 100Q - 4Q^2 , MR = 100 - 8Q , MR at Q (10) = 20

Step-by-step explanation:

Demand curve ie Price as a function of Quantity ; P (Q)  = 100 - 4Q

R, total revenue from sale = Q . P (Q)

R (Q) = (100 - 4Q) Q  

MR is addition to total revenue due to per unit change in sale, = d R / d Q

d ( 100Q - 4Q^2 ) / d Q  

MR at quantity , 10 unit of sales = 100 - 8 (10)

MR at Q (10) = 20

Answer:

x = 1

Step-by-step explanation:

We want to solve the equations for x

-2.4x-3.6y = 1.2

2.4x + 1.2y = 1.2

Add the two equations

-2.4y = 2.4

y = 2.4/-2.4

y = -1

To get x, simply substitute the y-value into any of the equations;

2.4x + 1.2y = 1.2

2.4x + 1.2(-1) = 1.2

2.4x -1.2 = 1.2

2.4x = 1.2 + 1.2

2.4x = 2.4

x = 2.4/2.4

x = 1
