The marked price of a drawing table is $12,90 if a discount going to be 18%is offered on the table what is the sale price?

When you solve an equation for one variable and then substitute the resulting expression in for that variable in the other equation its is known as Substitution method.

I will demonstrate how the substitution method works. Suppose we have the following systems of linear equations with two variables:

Equation 1:  3x + 2y = 11

Equation 2:  -x + y = 3

By solving these two equations we get x=1 and y=4.

Equation 2:  -x + y = 3

-x + x + y = x + 3

y = x + 3

Next, substitute the value of y in Equation 2 (from the previous step), and substitute its value into Equation 1 to solve for x:

Equation 1:  3x + 2y = 11

Substitute y = x + 3 into Equation 1:

3x + 2(x + 3) = 11

3x + 2x + 6 = 11

Combine like terms:

5x + 6 = 11

5x + 6 - 6 = 11 - 6

5x = 5

Divide both sides by 5 to solve for x:

[tex]\frac{5x}{5} = \frac{5}{5}[/tex]

x = 1

Substitute the value of x into Equation 2 to solve for y:

Equation 2:  -x + y = 3

-1 + y = 3

y = 3 + 1

y = 4

The two boys are far away from the resort and distance measured about 35.81m.

The Pythagoras theorem equation is written as c² = a² + b², with c denoting the hypotenuse of the right triangle and a and b denoting the other two legs. So, any triangle that has a 90° angle creates a Pythagoras triangle, which can then be solved using the Pythagoras equation.

We must first use the Pythagoras theorem to determine how far the resort is from Manuel's home.

S₁ = √50²+20²

S₁ = √2500+400

S₁ = √2900

The coordinates of the vertex of the function y = -3x² -12x + 3 is (-2,15) and the graph of the function is attached below.

Vertex in math is known as a point on a polygon where the sides or edges of the object meet or where two rays or line segments meet.

Here we have given that the function y = -3x² - 12x + 3 and we have to find the coordinates of the vertex.

As we all know that for any equation of the type y = ax² + bx + c the vertex is given by (h, k)

And the value of the vertex is calculated by using the formula  h = -b/2a and k = (4ac - b2)/4a.

From the given question we have identified the value of  a = -3, b = -12 and c = 3

Then the value of h is calculated as,

=> h = -(-12)/2(-3)

When we simplify this one then we get the value of h as -2

Similarly the value of k is calculated as,

=> 4ac = 4(-3)(3) = -36

Then the equation is written as,

=> k = [-36 - (-12)2]/4(-3)

When we simplify this one then we get

=> k = -180/-12

Therefore, the value of k is 15

Hence the coordinates of the vertex is (h, k) = (-2, 15).

Answer:

23.6 units.

Step-by-step explanation:

Since quadrilateral DEFG is similar to quadrilateral HIJK, the ratios of corresponding sides are equal. We can use this information to find the measure of IJ.

We know that:

DF/HJ = EF/IJ = 6/23.6 = 2/8 = 1/4

So we can set up the proportion:

IJ/EF = HJ/DF

IJ/6 = 23.6/6

IJ = 23.6/6 * 6 = 23.6

The given expression is expressed in an algebraic expression as: y^5 + 11

To produce g, function was reflected over the x-axis and | shifted up 3 units . Function g can be defined as g(x)=f(x-1)+4.

What is axis ?

An axis is a straight line around which an object or a geometric shape can rotate or be symmetrical. In a coordinate system, an axis is a line that serves as a reference for the location of points in space.

When a function f(x) is reflected over the x-axis, it changes the sign of the y-coordinate values. By reflecting the graph of f(x) over the x-axis, the new function g(x) will have the same shape as f(x) but with all y-coordinate values inverted.

Additionally, by shifting the function up 3 units, it means that the y-coordinate values of the new function g(x) will be 3 units greater than the y-coordinate values of the original function f(x).

So the transformation can be represented as:

g(x) = f(x-1) + 4

It is the horizontal shift of 1 unit to the right, and a vertical shift of 3 units up

Answer:

The given expression is -7xy^3z^2

The degree of x is 1

The degree of -7 is 0

The degree of y^3 is 3

The degree of z^2 is 2

The degree of a polynomial is the highest exponent of its variables. In the case of the polynomial -7xy^3z^2, the degree is the highest exponent among x, y, and z.

The highest exponent is 3, which is the exponent of y. So the degree of the polynomial -7xy^3z^2 is 3.

It's worth noting that the coefficient -7 has no effect on the degree of the polynomial. The degree of a polynomial is determined by the exponents of its variables, not its coefficients.

∫(f(x) + g(x)) dx = ∫f(x) dx + ∫g(x) dx is the sum rule in integration.

The sum rule in integration states that if f(x) and g(x) are two functions that are both integrable over a given interval, then the integral of the sum of these functions over that interval is equal to the sum of the integrals of the individual functions over that interval. Mathematically, this can be expressed as:

∫(f(x) + g(x)) dx = ∫f(x) dx + ∫g(x) dx

The sum rule of integration is: Integral of the sum of two functions is equal to the sum of integration of individual functions.

Correct option is A,  f(x) -2 has changed the parent function f(x) = (0.5)x to its new appearance.

The parent function f(x) = log5x has been modified by reflecting it over the x-axis, extending it vertically by a factor of three, and moving it down by three units.

In the picture below you can see the blue line is the graph of the function

f(x) = log(5x) and the green line is the graph of the function

g(x) = log[5(x + 4)] - 2

Since the function f passes at point (2, 1), we must reduce it by 2 units to ensure that it also passes at position (-2, -1). To do this, we add 2 to the function f.

We only need to add 4 to the variable x to have the function go left when we obtain log(5x) - 2.

The function shifts to the left when you add a number to x;

The function moves to the right when you remove a number from x;

The function increases when you add a number to it;

The function decreases when you take a number away from it.

Then we get a function g(x) = log[5 (x + 4)] - 2.

To find the sine of an angle in a right triangle, we can use the following relationship:

[tex]sin(angle) = opposite side / hypotenuse\\[/tex]

What is right triangle?

A right triangle is a type of triangle that has one angle that measures exactly 90 degrees (also known as a right angle). This angle is formed by the intersection of two legs of the triangle, which are not the hypotenuse of the triangle. The side opposite the right angle is called the hypotenuse and it is always the longest side of the triangle.

To find the sine of an angle in a right triangle, you can use the following relationship:

[tex]sin(angle) = opposite side / hypotenuse\\[/tex]

This relationship holds true for any angle in a right triangle, not just the acute angles.

For example, if you have a right triangle with an angle of 30 degrees and the opposite side is 5 units and the hypotenuse is 12 units, you can find the sine of the angle by dividing the opposite side by the hypotenuse:

[tex]sin(30) = 5/12 = 0.4166\\[/tex]

It's also important to note that the sine of an angle is always between -1 and 1, and the sine of an acute angle is always positive.

The difference between the largest 5-digit number and the smallest 6-digit number is 1.

The aim is to find the largest 5-digit and the smallest 6-digit numbers, and then we need to identify the difference between these two values.

Let's start by finding the smallest 6-digit number.

We know that 0 is the smallest digit that can not be used in the highest place value, so we will consider the next smallest digit; that is, 1 and 1 can be used in the highest place value.

Thus, we can create the required 6-digit smallest number with 0 and 1.

Hence, the smallest 6-digit number is 100000.

Now, we will discover the largest 5-digit number.

As we know, the largest digit is 9, which can be used anywhere. So, we will form the largest 5-digit number with the digit 9.

Thus, the largest 5-digit number is 99999.

Next, we need to find the difference between these two values.

So, we can determine the difference between the smallest 6-digit number and the largest 5-digit number by subtracting the smallest from the largest.

Thus, we get,

⇒100000 - 999999

⇒1

Hence, 1 is the difference between the smallest 6-digit and the largest 5-digit numbers.
