Solve the following equation: 3x^3+5x^2-4x-4=0

Answer:

The answer is b. $ 74.75

Step-by-step explanation:

Data:

Let x be the value of items to be insured.

1. if the items are more than $ 3 000 it means that x is greater than  $  3000 and the annual premium will be 23 % of the total value.

2. if the items are less or equal to  $ 3 000, it means that x ≤ $ 3 000 ( in other words, x is less than or equal to $ 3 000)

The annual premium for the goods will be:

annual premium = 23 % × $ 3900

                          = $ 897

However, the premium is supposed to be paid monthly. Divide the total premium by 12 to get:

$ 897/12 = $ 74.75

This is option c.

Answer:

x = 3 or x = -3

Step-by-step explanation:

If x^2 - 9 = 0 we transfer 9 to the right side of the equation and it's change negative sign to positive while doing so

now we have x^2 = 9 the square of a number must be equal to a positive number in real numbers

but the root can be either negative or positive so we say x = 3 or x = -3

Answer:

4.2

Step-by-step explanation:

5.7-1.5=4.2

Answer: x = 4.2

Explanation: If we're asked to solve for x in the equation x + 1.5 = 7.5, what we're really being asked to do is get x by itself on one side of the equation.

So if we take a look at the left side of our equation, notice that 1.5 is being added to x so in order to get x by itself, we must subtract 1.5 from the left side of the equation. Now remember your first rule of solving equations. If we subtract 1.5 from the left side of the equation, we must also subtract 1.5 from the right side of the equation.

So on the left side our +1.5 and -1.5 cancel out and we're simply left with x. On the right side of the equation,

5.7 - 1.5 simplifies to 4.2 so our answer is x = 4.2.

The nice thing about solving equations is that you can always check your answer by plugging it back in to the original equation.

So here, we're gonna plug a 4.2 back in for x in the original equation and we get (4.2) + 1.5 = 5.7.

Since 4.2 + 1.5 = 5.7 is a true statement, our answer checks and we know that it's right.

Answer:

36

Step-by-step explanation:

Easy math all you have to do is look at he problem

For this case we have the following system of equations:

[tex]x + y = -9\\4x + y = -19[/tex]

We multiply the first equation by -4:

[tex]-4x-4y = 36[/tex]

We have the following equivalent system of equations:

[tex]-4x-4y = 36\\4x + y = -19[/tex]

We add the equations:

[tex]-4x + 4x-4y + y = 36-19\\-3y = 17\\y = - \frac {17} {3}[/tex]

We find the value of the variable "x":

[tex]x = -9-yx = -9 - (- \frac {17} {3})\\x = -9 + \frac {17} {3}\\x = \frac {-27 + 17} {3}\\x = - \frac {10} {3}[/tex]

Thus, the solution of the system is:

[tex](x, y): (- \frac {10} {3}, - \frac {17} {3})[/tex]

Answer:

2) Option 9.4 is correct

Therefore the length of the given line segment is [tex]s=9.4[/tex] units

3) Option (1,1) is correct

Therefore the midpoint of the given line  segment is M=(1,1)

Step-by-step explanation:

2) Given that the line segment CD with endpoints C at (-3,1) and endpoint at D (5,6)

To find the length of the given line segment :

That is to find the distance of the end points using distance formula

[tex]s=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex] units

Let [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] be the given points (-3,1) and (5,6) respectively

Substitute the points in the distance formula we have

[tex]s=\sqrt{(5-(-3))^2+(6-1)^2}[/tex] units

[tex]=\sqrt{(5+3)^2+(5)^2}[/tex] units

[tex]=\sqrt{8^2+5^2}[/tex]

[tex]=\sqrt{64+25}[/tex]

[tex]=\sqrt{89}[/tex]

[tex]=9.4[/tex]

Therefore [tex]s=9.4[/tex] units

Option 9.4 is correct

Therefore the length of the given line segment is [tex]s=9.4[/tex] units

3) Given that the line segment PG with point P at (-6,4) and point at G (8,-2)

To find the midpoint of the given line segment :

Midpoint formula is [tex]M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

Let [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] be the given points (-6,4) and  (8,-2) respectively

Substituting the points in the midpoint formula we get

[tex]M=(\frac{-6+8}{2},\frac{4-2}{2})[/tex]

[tex]=(\frac{2}{2}+\frac{2}{2})[/tex]

[tex]=(1,1)[/tex]

Therefore M=(1,1)

Therefore option (1,1) is correct

Therefore the midpoint of the given line  segment is (1,1)

Answer:

y = 36x

Step-by-step explanation:

Given that x and y vary directly then the equation relating the is

y = kx ← k is the constant of variation

To find k use the condition x = [tex]\frac{1}{3}[/tex], y = 12, then

k = [tex]\frac{y}{x}[/tex] = [tex]\frac{12}{\frac{1}{3} }[/tex] = 12 × 3 = 36

Answer:

a = −6

Step-by-step explanation:

Step 1: You should divide both sides by 2.

have an amazing day! (❁´◡`❁)

Step-by-step explanation:

The word equation for "eight more than the number of children is 24" can be written as:

Number of children + 8 = 24

Let's break it down step by step:

1. Identify the unknown: The unknown in this equation is the number of children. Let's represent it as "x".

2. Translate "eight more than the number of children" into mathematical language: "Eight more than" means adding 8 to the number of children.

3. Write the equation: The equation becomes x + 8 = 24.

To find the value of x, we need to isolate it on one side of the equation. We can do this by subtracting 8 from both sides:

x + 8 - 8 = 24 - 8

Simplifying further:

x = 16

Therefore, the number of children is 16.

It's important to note that the word equation can be translated into different mathematical expressions. For example, another way to represent "eight more than the number of children is 24" would be:

Number of children = 24 - 8

This equation would also yield the same answer: 16.

Remember, word equations help us represent real-life situations in mathematical form, allowing us to solve problems and find solutions.
