The integer solutions of the system of inequalities are x >= 1 and b <= 0

Inequality expressions are mathematical statements that are represented by variables, coefficients and operators where the opposite sides are not equal

System of inequalities 1

Here, we have

3 - 18x < 0

0.2 - 0.1x > 0

Rewrite as

0 < 0.2 - 0.1x

The above means that

3 - 18x  < 0.2 - 0.1x

Collect the like terms

So, we have

3 - 0.2 < 18x + 0.1x

Evaluate the like terms

So, we have

2.8 < 18.1x

Divide both sides by 18.1

So, we have

0.155 < x

Rewrite as

x > 0.155

The integer value greater than 0.155 is at least one

Hence, the integer solution of the system is x >= 1

System of inequalities 2

Here, we have

6 - 4b > 0

3b - 1 > 0

The above means that

6 - 4b > 0 < 3b - 1

Collect the like terms

So, we have

-4b > - 6 + 0 + 1< 3b

Evaluate the like terms

So, we have

-4b > -5 < 3b

Solve for b

b < -1.25 or -1.67 < b

The integer values in this case are 0

So, we have

b <= 0

Hence, the integer solution of the system is b <= 0

The expansion and simplified form of the expression [(x+3)(2x-1)(x+4)] will be (2x³ + x² - 25x - 12).

As per the question statement, we are provided with the expression of [(x+3)(2x-1)(x+4)] where three separate factors of the variable "x" are multiplied with each other.

We are required to expand and simplify the above-mentioned expression to obtain our desired answer.

Given, [(x + 3)(2x - 1)(x + 4)]

= [{(x + 3)*(2x - 1)}(x + 4)]

= [{(x*2x) - (x*1) + (3*2x) - (3*1)}(x + 4)]

= [(2x² - x - 6x -3)(x + 4)]

= [(2x² - 7x -3)(x + 4)]

= [(2x²*x) + (2x²*4) - (7x*x) - (7x*4) - (3*x) - (3*4)]

= [2x³ + 8x² - 7x² - 28x - 3x - 12]

What is equation of line in slope intercept form?

The most general form of equation of line in slope intercept form is given by y = mx + c

Where m is the slope of the line and c is the y intercept of the line.

Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.

If [tex]\theta[/tex] is the angle that the line makes with the positive direction of x axis, then slope (m) is given by

m = [tex]tan\theta[/tex]

The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.

The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.

The perimeter of each pool is 92 ft.

What is perimeter?

A perimeter is a closed route that covers, surrounds, or outlines a two-dimensional form or length. The circumference of a circle or an ellipse is its perimeter.

Given, the triangles are congruent so,

20x-15 = 15x+15

=> 20x-15x = 15+15

=> 5x = 30

=> x = 30/5 = 6

Therefore, perimeter = (4x-4) + (5x+1) + 41

                                    = (4x6 - 4) + (5x6 + 1) + 41

                                    = 20 + 31 + 41

What is Rectangle?

A rectangle is a quadrilateral that has parallel sides equal to each other and all the four angles are equal to 90 degrees.

Given that;

Length of a rectangle = 60 cm

Width of a rectangle = 91 cm

Now,

Since, We know that;

Diagonal of a rectangle (D) = √Length² + Width²

Substitute all the values we get;

Diagonal of a rectangle (D) = √Length² + Width²

                                         = √60² + 91²

                                         = √3600 + 8,281

                                         = √11,881

Hope this helps

Answer:

Yeah

Step-by-step explanation:

but i can also do it in opposite

Main Answer:

Explanation:

Given that,

[tex]\frac{dA}{dt}[/tex] = -4

The surface area of the snow ball = 4π[tex]r^{2}[/tex]

Let the surface area = A

If A denotes the surface area and D the diameter then,

A = 4π[tex]r^{2}[/tex] = 4π[tex](\frac{D}{2} )^{2}[/tex]

⇒ A = π[tex]D^{2}[/tex]

Differentiate with respect to r,

[tex]\frac{dA}{dD}[/tex] = 2πD

By using chain rule,

[tex]\frac{dA}{dD}[/tex] = [tex](\frac{dA}{dt})[/tex][tex](\frac{dt}{dD})[/tex] = [tex]\frac{\frac{dA}{dt}}{\frac{dD}{dt}}[/tex]

⇒ 2πD = [tex]-\frac{4}{\frac{dD}{dt}}[/tex]

∴ [tex]\frac{dD}{dt}[/tex] = [tex]-\frac{4}{2\pi\\D}[/tex]

when D = 9,

[tex]\frac{dD}{dt}[/tex] = [tex]-\frac{4}{18\pi}[/tex]

∴ [tex]\frac{dD}{dt}[/tex] = [tex]-\frac{2}{9\pi}[/tex]

so, the diameter is decreasing at a rate of [tex]\frac{2}{9\pi}[/tex] .

An equation is an expression that shows the relationship between two or more numbers and variables.

Equations are classified based on degree (value of highest exponents) as linear, quadratic, cubic and so on. Variables can be dependent or independent. Dependent variables depend on other variable while an independent variable do not depend.

A polynomial is an expression that involves only the operations of addition, subtraction, multiplication, and positive exponent powers of variables. If the expression has a negative exponent, it is not a polynomial.
