What is the value of x?



Enter your answer in the box.

The solution of the quadratic equation 2x² + 8x = x² - 16 is given as a negative of 4.

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

The equation is given below.

2x² + 8x = x² - 16

Then on simplifying, we have

       x² + 8x + 16 = 0

x² + 4x + 4x + 16 = 0

      (x + 4)(x + 4) = 0

              (x + 4)² = 0

                        x = -4

Using the given function, it is found that:

The profit when n students are enrolled in the class is given by:

f(n) = 70n - 400.

A profit is made when f(n) > 0, hence:

70n - 400 > 0

70n > 400

n > 5.71.

6 students need to be enrolled for the instructor to make a profit.

A profit of $1,000 is made when f(n) = 1000, hence:

70n - 400 = 1000

70n = 1400.

n = 20.

20 students must be enrolled for the instructor to make a profit of $1,000 a month.

Answer:

871

Step-by-step explanation:

The State Board of Education can buy 871 calculators with the available budget.

Here, we have to find out how many calculators the State Board of Education can buy,

We have to divide the total amount they have ($1,742) by the cost of each calculator ($2):

So, we get,

Number of calculators = Total amount / Cost per calculator

Number of calculators = $1,742 / $2

Number of calculators = 871

So, the State Board of Education can buy 871 calculators with the available budget.

Answer:

Joe is 16, Frank is 22

Step-by-step explanation:

To find the solution to this problem, we first divide 38 by two.

38 / 2 = 19.

Then, we subtract 6 from 19 and have 19 and 13.  Obviously, 19 is 6 more than 13 (19 - 13 = 6).  Now, we need to make sure our number on the left is always 6 more than the number on the right.  19 + 3 = 22, 13 + 3 = 16.  Since Frank is older than Joe by 6 years, we get 22 and 16 as their ages.

The total amount of security deposit, deposited by three friends after paying the rent is $620.01. Option C is the correct option.

The monthly payment is the amount which is required to pay each month to pay off the borrowed principal amount or the rent of a service charged monthly.

The rent of the apartment is $650 per month. The rent for the two months (first and last) is,

[tex]\rm M = 2\times 650\\\\M =1300[/tex]

This rent is paid by three friends. Thus, the amount which is paid by an individual friend is,

[tex]\rm P=\dfrac{1300}{3}\\\\P=433.33[/tex]

They each paid $640 towards the total move-in cost of first and last month's rent and a security deposit. Therefore,

[tex]\rm P=640-433P=206.67\\\\[/tex]

Thus, $206.67 is paid by each of them towards security deposits. The total amount of security deposit, deposited by 3 of them, is,

[tex]\rm SD=206.67\times 3\\\\SD=620.01[/tex]

Hence, the total amount of security deposit, deposited by three friends after paying the rent is $620.01. Option C is the correct option.

The negative one is the third root of the equation x³ - 4x² + 2x + 10. Then the correct option is B.

Polynomial is an algebraic expression that consists of variables and coefficients. Variables are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.

The polynomial equation is given below.

[tex]\rm x ^3-4 x ^2+2 x+ 10 = x ^2 -5 x-3[/tex]

The equation can be written as

[tex]\rm x ^3-5 x ^2+7 x+ 13 = 0[/tex]

The equation has a complex root [tex]- 3 \pm 2 \iota[/tex]

Put x = -1, then we have

[tex]\begin{aligned} (-1) ^3-5 (-1) ^2+7 (-1)+ 13 = 0\\\\-1 - 5 - 7 + 13 = 0\\\\0=0 \end{aligned}[/tex]

Step-by-step explanation: The formula to calculate the area of a regular polygon is, Area = (number of sides × length of one side × apothem)/2, where the value of apothem can be calculated using the formula, Apothem = [(length of one side)/{2 ×(tan(180/number of sides))}].

Answer:

[tex]y =\dfrac{1}{2}x+4[/tex]

Step-by-step explanation:

Slope-intercept form: y =mx +b

              7x - 14y = -56

Step1 : subtract 7x from both sides

                   [tex]-14y = -7x - 56[/tex]

Step2: now divide both sides by (-14)

                         [tex]y =\dfrac{-7}{-14}x -\dfrac{56}{-14}\\\\y = \dfrac{1}{2}x+ 4[/tex]

Answer:

y = [tex]\frac{1}{2}[/tex] x + 4

Step-by-step explanation:

7x - 14y = - 56 ( subtract 7x from both sides )

- 14y = - 7x - 56 ( divide through by - 14 )

y = [tex]\frac{-7}{-14}[/tex] x - [tex]\frac{56}{-14}[/tex]

y = [tex]\frac{1}{2}[/tex] x + 4 ← in slope- intercept form

We will see that the linear equation is:

y = 1.1*x  -13.5

b) The predicted height is 164.7cm

A general linear equation is:

y = a*x + b

Where a is the slope and b is the y-intercept.

If we know that the line passes through (x₁, y₁) and (x₂, y₂), then we can write the slope as:

a = (y₂ - y₁)/(x₂ - x₁)

In this case, the line passes through (165, 168) and (174, 178), then the slope is:

a = (178 - 168)/(174 - 165) = 10/9 = 1.1

Then the line is:

y = 1.1*x + b

To get the value of b, we use one of the given points, for example if we use the first one (165, 168) we must have x = 165 and y = 168, replacing that we get:

168 = 1.1*165 + b

168 -  1.1*165  = b = -13.5

The equation is:

y = 1.1*x  -13.5

Now we want to find the height of a person with an arm span of 162cm, then we replace x by 162 to get:

y = 1.1*162 -13.5 = 164.7

The predicted height is 164.7cm

Answer:

4. y=3√2 and x=36

Step-by-step explanation:

Here,

interior angle of triangle = 180°

So, 90°+45°+45°=180°

Therefore, the triangle is isosceles triangle

So,

y=3√2 (the corresponding sides of corresponding angle of isosceles triangle are equal)

Again, x^2=(3√2)^2 + (3√2)^2

or, x= √(18 + 18)

or, x=√36
