can you answer this and explain please ​

Answer:

the answer is =7.6n+0.8

Step-by-step explanation:

hoped I helped

k=-36

Step-by-step explanation:

x inversely proportional to y

x=1k/y

where k = constant

x= -3, y= 12, k = ?

-3=k/12

k = -3 × 12

k = -36

Answer:

8

Step-by-step explanation:

Cross reduce, you then get:

12x+48=18x

12x-18x=-48

-6x=-48

x=8

Answer: y=2x+6

Step-by-step explanation:

Answer:

(i) (x + 3) is a factor of p(x)= x⁴ + 4x³ + 4x² + 4x + 3 and the remaining factors are (x + 1) and ( x²  +  1).

(ii) (x + 1) is not a factor of p(x)= 2x⁴ - 5x² - 2 and the remainder is -5.

Step-by-step explanation:

(i) Given;

Polynomial, p(x)= x⁴ + 4x³ + 4x² + 4x + 3

Factor, = x + 3

            x = -3

if (x + 3) is a factor of the polynomial, then p(-3) = 0

p(-3) = (-3)⁴ + 4(-3)³ + 4(-3)² + 4(-3) + 3

        = 81 -108 + 36 - 12 + 3

        = 0

(x + 3) is a factor of the given polynomial and the remainder is 0.

The remaining factors can be obtained as follows;

               x³  +  x² + x + 1

            --------------------------------

x + 3 √x⁴ + 4x³ + 4x² + 4x + 3

        - ( x⁴  + 3x³)

          --------------------------------

                    x³ +  4x² + 4x + 3

                   -(x³  + 3x²)

          ----------------------------------

                            x² + 4x + 3

                          -(x²  + 3x)

         ---------------------------------------

                                     x + 3

                                   -(x + 3)

           ---------------------------------------

                                          0

 Further divide x³  +  x² + x + 1  by x + 1

                      x²  +  1

                    ---------------------

        x + 1 √x³  +  x² + x + 1

                 -(x³  +  x²)

                  ------------------------

                                   x +  1  

                                 -( x  + 1)

                             -----------------

                                      0              

Thus, the factors of  x⁴ + 4x³ + 4x² + 4x + 3 = (x + 3)(x + 1)( x²  +  1)

(ii) Given;

Polynomial, p(x)= 2x⁴ - 5x² - 2

Factor, = x + 1

            x = -1

if (x + 1) is a factor of the polynomial, then p(-1) = 0

p(-1) = 2(-1)⁴  - 5(-1)² - 2

       = 2 - 5 - 2

       = -5

Thus, (x + 1) is not a factor of the given polynomial and the remainder is -5.

Answer:

As this question is incomplete, but we will try to solve this question by adding our own data to understand the concept of the problem.

Explanation is given below

Step-by-step explanation:

As this question is incomplete, but we will try to solve this question by adding our own data to understand the concept of the problem.

In order to answer this question we need to have the dimensions of the box.

Let's suppose there are 6 outside surfaces of the box and are equal in dimension including the bottom side which Jan wants to varnish.

So,

Let's suppose,

Surface area of the cube = 6[tex]a^{2}[/tex]

Here, Surface area = 275 square inch

Surface area of the cube = 6[tex]a^{2}[/tex] = 275 square inch

[tex]a^{2}[/tex] = 275/6 = 45.833

a = [tex]\sqrt{45.833}[/tex]

a = 6.77 inches

Now, for the amount of the varnish, we need the spreading rate of the varnish to be used on the box,

Let's suppose it is = 11 square incher per litre.

So,

Required Varnish = Surface area / Spreading rate

Required varnish = 275 / 11

Required varnish = 25 liters

If the 1 container of varnish contains 25 liters then it will be sufficient to protest the outside surfaces of the box.

Answer:

Each computer needs 3/2, or 1.5 feet of cable

Step-by-step explanation:

Firstly, we need to divide 4 1/2 by 3

Then we can make 4 1/2 an improper fraction.

We will also multiply 4 by 2 and then add 1

= 8 + 1

= 9

But;

9/2 = 4 1/2

In order to divide 9/2 by 3/1, we will change 3/1 to 1/3 and then multiply

= 9/2 × 1/3

= 9/6

= 3/2 or 1.5

Therefore, each computer needs 3/2, or 1.5 feet of cable.

Answer:

[tex]\huge \orange {\boxed {y = - \frac{5}{4}x + 5}} [/tex]

Step-by-step explanation:

Line is intersecting x and y axes at the points (4, 0) & (0, 5)

So, y- intercept (b) = 5

[tex] Slope\: (m) = \frac {(5-0)}{(0-4)} = - \frac {5}{4} [/tex]

Equation of line in slope intercept form is given as:

[tex] y = mx + b[/tex]

Plugging the values of m and b in the above equation, we find:

Step-by-step explanation:

I dunno if this is right but i got this.

Answer:

Substituting for a Variable

If you know the value that the variable is equal to, you can substitute that value in for the variable in the expression! Let's look at an example. Since we know that x=5, we can directly substitute or replace the x in the expression x+3 with a 5 to solve for y!

Step-by-step explanation:

I hope this kinda helps

Answer:

The out-of-state tuition would be $8800.

Step-by-step explanation:

Given that:

The ratio of in-state tuition to out-state tuition = 3:11

If the tuition of in-state is $2400.

Let,

x represent the number of out-of-state tuition.

As the relation is directly proportional.

3 : 11 :: 2400 : x

Product of mean = Product of extreme

11*2400 = 3x

3x = 26400

Dividing both sides by 3

[tex]\frac{3x}{3}=\frac{26400}{3}\\x=8800[/tex]

Hence,

The out-of-state tuition would be $8800.

Answer:

  (d)  Eighteen divided by a number m is seven point two.

Step-by-step explanation:

The symbol ÷ is read "divided by", so the math sentence ...

  18 ÷ m = 7.2

is read "eighteen divided by [a number] m is seven and two tenths."

__

"Seven and two tenths" can also be read as "seven point two."
