To graph lines, we can find two points in it and draw a line that passes through both.

Let's pick x = 0 and x = 1 for the first equation:

So, we plot the points (0, 1) and (1, 6).

For the inverse, we can simply invet the coordinates, which is the same as picking x = 1 and x = 6:

Thus, we have the points (1, 0) and (6, 1).

The line y = x is jus the diagonal that passes though point (0, 0) and (1, 1), for example.

Putting these points and drawing the lines, we get:

A die can have 6 possible outcomes.

The probability of an event is calculated using the formula:

The equation for 'P', representing Madeline's total pay on a day on which she sells 'x' computers is → P = 80 + 20x.

Given, At an electronics store, Madeline sells computers as a salesperson. She receives a $80-per-day base salary in addition to a $20 commission for each computer she sells.

What is Equation Modelling?

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We can model the equation for Madeline's total pay as follows -

P = base pay + (number of sold computer) × (cost of 1 computer)

P = 80 + 20x

Therefore, the equation for 'P', representing Madeline's total pay on a day on which she sells 'x' computers is → P = 80 + 20x

Hence, the probability of selecting a red marble is;

The expression has a value of -31 when a = 2 and b = –3

From the question, the expression is given as

5 – a(3² + (ab + 2)² – 7)

Also, we have the values of the variables to be

a = 2 and b = –3

Substitute a = 2 and b = –3 in the expression 5 – a(3² + (ab + 2)² – 7)

So, we have the following equation

5 – a(3² + (ab + 2)² – 7) = 5 – 2 * (3² + (2 * -3 + 2)² – 7)

Evaluate the expressions in the bracket

5 – a(3² + (ab + 2)² – 7) = 5 – 2 * (3² + (-4)² – 7)

Evaluate the exponents

5 – a(3² + (ab + 2)² – 7) = 5 – 2 * (9 + 16 – 7)

So, we have

5 – a(3² + (ab + 2)² – 7) = 5 – 2 * 18

This gives

5 – a(3² + (ab + 2)² – 7) = 5 – 36

Evaluate the difference

5 – a(3² + (ab + 2)² – 7) = -31

Hence, the value of the expression is -31

The Pythagoras theorem gives the relation for the right-angle triangle between the perpendicular, base, and hypotenuse thus the perpendicular x will be 14.70.

A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices.

Triangle is a very common figure to deal with in our daily life.

In a triangle, the sum of all three angles is 180°

As per the given right-angle triangle,

Pythagoras' theorem states that in a right-angle triangle →

Hyp² = Perp² + Base²

In the given triangle Hyp = 21 , Base = 15 and Perp = x

So,

21² = x² + 15²

x² = 21² - 15²

x = √216 = 14.6993 ≈ 14.70

Hence "The value of x for the given right-angle triangle is 14.70 units".

The sides of the triagle have lengths:

1.1 p + 9.5 q

4.5 p - 5.2 r

5.3 r + 5.4 q

Or:

1.1 p + 0 r + 9.5 q

4.5 p - 5.2 r + 0 q

0 p + 5.3 r + 5.4 q

If we want to calculate the perimeter of the triangle, we just need to sum the three lenghts:

(1.1 + 4.5) p + (-5.2 + 5.3) r + (9.5 + 5.4) q

= 5.6 p + 0.1 r + 14.9 q

The measure of angle 1 is 71º, we can find this, because angle 1 and angle x form a straight line of 180º, so 180º - 109º = 71º

The measure of angle 2 is also 71º, we can use the vertical angles propierty, then m∠1 = m∠2

The measure of angle 3 is 109º, we can use again the vertical angles theorem to find that m∠x = m∠3

Themeasure of angle 7 is 109º. We need to use the alternating exterior angles theorem. Since angle x and angle 7 are not between the parallel lines they're exterior angles; and since they're on opposite sides of the transversal line, they're alternates. Then the theorem says that m∠x = m∠7

The measure of angle 6 is 71º, again we're using the fact that angle 7 and angle 6 forms a straight line, then m∠6 = 180º - 109º = 71º

Now we can find the lasts two measures using the vertical angles theorem.

The measure of angle 5 is 71º, because m∠6 = m∠5

The measure of angle 4 is 109º, because m∠7 = m∠4

You have:

sin 2A = -√7/4

In order to determine the value of sin A, first calculate the value of angle A by using sin⁻¹ over the previous equation, just as follow:

sin⁻¹(sin 2A) = sin⁻¹(-√7/4) In this way you cancel out the sin

2A = -41.41° divide by 2 both sides

A = -41.41°/2

A = -20.705°

however, take into account that angle A is in the third quadrant. Then, it is necessary to consider the result A=-20.705° is respect to the negative x-axis.

To obtain the angle respect the positive x-axis (the normal way), you simply sum 180° to 20.705°:

20.705 + 180° = 200.705°

Next, use calculator to calculate sinA:

sin(200.705°) = -0.3535
