If the cost of making the dish is $6.75, and he wants to make a 33% profit on each dish he sells. adam's selling price is: $8.98.

Using this formula to find the selling price

Selling price = Cost price + (Cost price × Profit percentage)

Let plug in the formula

Selling price = $6.75 + ($6.75 × 33%)

Selling price = $6.75 + $2.2275

Selling price = $8.977

Selling price = $8.98 (Approximately)

Therefore the selling price is the amount of $8.98

The values of x and y that makes the expression are x = 4 and y = -5

The expression is given as

(4 + 5i)(x + yi)

The above expression is a complex expression

As a general rule, complex expressions are represented as a + bi

Where a is the real part and bi is the complex part

Also, we have

i = √-1

Using the above as a guide, we have

(4 + 5i)(x + yi)

For the above expression to be a real number, then the following must be true

(4 + 5i) must be a conjugate of (x + yi)

This means that

x + yi = 4 - 5i

By comparison, we have

x = 4 and y = -5

Answer:

[tex]x\sqrt{3x}[/tex]

Step-by-step explanation:

Given expression to simplify:

[tex]4x\sqrt{3x}-x\sqrt{3x}-2x\sqrt{3x}[/tex]

Factor out the common term [tex]\sqrt{3x}[/tex] :

[tex]\implies \sqrt{3x}(4x-x-2x)[/tex]

Carry out the operations inside the parentheses:

[tex]\implies \sqrt{3x}(3x-2x)[/tex]

Answer:

a) x√(3x)

Step-by-step explanation:

We have to simplify,

→ 4x√(3x) - x√(3x) - 2x√(3x)

Then the simplest form is,

→ 4x√(3x) - x√(3x) - 2x√(3x)

→ 4x√(3x) - 3x√(3x)

→ x√(3x)

Hence, option (a) is correct.

The length of each segment ST = 63, TU = 63, SU = 126

The midpoint theorem states that “The line segment in a triangle joining the midpoint of two sides of the triangle is said to be parallel to its third side and is also half of the length of the third side.”

From the given figure

ST = 9x

TU = 5x+28

According to midpoint theorem,

ST = TU

9x = 5x+28

9x-5x = 28

4x = 28

x = 7

It means,

ST = 9×7 = 63

TU = 5×7+28 = 35+28 = 63

SU = ST+TU

     = 63+63

ST = 126

Hence, The length of each segment ST = 63, TU = 63, SU = 126

The median of the legs of a triangle joins the vertex to the midpoint of the opposite side of the triangle. Hence, they are congruent. The correct postulate is (D) SAS See proof below.

Congruent triangles are those with the same size and form. This signifies that the respective sides are equal, as are the corresponding angles.

The median of a triangle's legs connects the vertex to the midway of the opposing side of the triangle. An isosceles triangle has two sides and angles that are congruent.

This suggests that postulates AAA and SSS are ruled out.

This is because both postulates entail that the triangles' sides and angles are congruent.

Sides AB and AC are congruent (S)

Sides CD and BD are also congruent (S)

Angles at D on both triangles are congruent (A)

The quadratic function that includes the given points is given by y = 3/5x² + 6/5x + 6.

When a polynomial function has one or more variables and the highest exponent of any one of the variables is two, the function is said to be quadratic. A "polynomial function of degree 2," then, is a quadratic function.

A quadratic function is one that has the formula f(x) = ax2 + bx + c, where a, b, and c are all integers with a not equal to zero. A parabola is the shape that makes up the graph of a quadratic function. The basic "U" shape of a parabola is the same whether it opens upward or downward, or with a different "width" or "steepness."

If we put the values of points in the above equation, then we get.

Putting point (0,6) we get

6 = 0 + 0 + c

=> c = 6

Putting point (2,8) we get

8 = 4a + 2b + 6

=> 2 = 4a + 2b

=>  = 2a + b                  ......(1)

Putting point (3,-3) we get

-3 = 9a + 3b + 6

=> -9 = 9a + 3b

=> -3 = 3a + b                 ......(2)

From equation (1) b = 2a. Substitute the value of b in equation (2) we get

3 = 3a +  2a

=> a = 3/5

Now, b = 6/5

The quadratic function that includes the given points is given by y = 3/5x² + 6/5x + 6.

What is cross multiplication?
To discover the unknown values in a mathematical equation, we cross multiply the numbers in the equation. The method of cross multiplication is frequently employed to identify the missing variable in an equation. We multiply both the numerator and denominator of the provided expression or fractions.
If w/e = r/t is the given expression, then the formula for cross multiplication can be given as: w*t = r*e

For 11, comparing numerators by multiplying the 'x' on right with 2.5 we get, x - y = 2.5x ⇒ 1.5x + y = 0, only possible if y = -1.5x
Therefore, the blank in 11 should be filled using (-1.5x).
For 12, comparing numerators by multiplying LHS with 6 and RHS with 4, we get, 6(h + y) = 4(h - 12) ⇒ 6h + 6y = 4h - 12 ⇒ 6y = -2h -12
⇒ y = (-1/3)h -2
Therefore, the blank in 12 should be filled using (-1/3)h -2.
Similarly, using cross multiplication and equating denominators for the next four, the blank spaces can be constructively filled.

Answer

To eliminate x, we will multiply the second equatio by -3.

x = 7

y = 5

Explanation

To solve this, we first write the two equations

-3x - 7y = -56

-7x + 10y = 1

So, to solve this, we need to make sure the factors of x are the same numbers and of opposite signs

So, if we multiply the first equation by 7, we will need to multiply the second equation by -3 to obtain 21x and -21x for the two of them.

(-3x - 7y = -56) × 7

(-7x + 10y = 1) × -3

-21x - 49y = -392

21x - 30y = -3

We will then add the two equations and then the solution for the equation is obtained by solving for y first.

-21x + 21x - 49y - 30y = -392 - 3

0 - 79y = -395

-79y = -395

Divide both sides by -79

(-79y/-79) = (-395/-79)

y = 5

We can then solve for x using any of the two equations

-7x + 10y = 1

-7x + 10(5) = 1

-7x + 50 = 1

-7x = 1 - 50

-7x = -49

Divide both sides by -7

(-7x/-7) = (-49/-7)

x = 7

The Domain of the relation is: -∞ < x <  ∞

The Range of the relation is: -∞ < y ≤ -3

What are Domain and Range?

The Domain of the function is the set of x-values for which the function is defined, whereas the Range of the function is the set of y-values for which it is defined.

Let us first determine the Domain.

On the x-axis, the curve starts from x = -∞, and ends at x = ∞  

So, the domain of the relation is: -∞ < x <  ∞  

Next, let us now determine the Range.

On the y-axis, the curve starts from y = -∞, and it ends at y = -3

The Range of the relation is: -∞ < y ≤ -3
