BONUS QUESTION: Is it true or false that each system of linear equations
has either one solution, no solutions OR an infinite number of solutions?

Answer:

Standard form is a way of writing down very large or very small numbers easily. 103 = 1000, so 4 × 103 = 4000. So 4000 can be written as 4 × 10³. This idea can be used to write even larger numbers down easily in standard form. Small numbers can also be written in standard form.

Factored form, the product of a constant and two linear terms: or. The parameters and are the roots of the function (the x-intercepts of the graph ). Converting a quadratic function to factored form is called factoring.

The y -intercept of a graph is the point where the graph crosses the y -axis. (Because a function must pass the vertical line test , a function can have at most one y -intercept . ) The y -intercept is often referred to with just the y -value.

The x-intercept is the point where a line crosses the x-axis, and the y-intercept is the point where a line crosses the y-axis. and vertex is

In geometry, a vertex (in plural form: vertices or vertexes), often denoted by letters such as, is a point where two or more curves, lines, or edges meet. As a consequence of this definition, the point where two lines meet to form an angle and the corners of polygons and polyhedra are vertices.

the legs are denoted as 'a' and 'b'

the Pythagorean Theorem allows you to find the missing side using this formula:

Total amount of water before it was drained will be 510 gallons.

"It is a ratio in which the two terms being compared have different units."

For given question,

We have been given  a table for  the number of gallons of water left in the tank after being drained for two amounts of time.

First we find the rate at which the water was drained from the tank.

[tex]r=\frac{450-330}{30-10}\\\\ r=\frac{120}{20}\\\\ r=6~gallons~per~minutes[/tex]

Let the amount of water in the tank before it was drained = 'x' gallons

And the initial time = 0

Using the rate formula,

[tex]r=\frac{x-450}{10-0}\\\\ 6=\frac{x-450}{10}\\\\ 60=x-450\\\\x=450+60\\\\x=510~gallons[/tex]

Therefore, total amount of water before it was drained will be 510 gallons.

Answer:x=√−y2+18y−56 or x=−√−y2+18y−56

Step-by-step explanation:

x2+(y−9)2=25

Step 1: Add -y^2 to both sides.

x2+y2−18y+81+−y2=25+−y2

x2−18y+81=−y2+25

Step 2: Add 18y to both sides.

x2−18y+81+18y=−y2+25+18y

x2+81=−y2+18y+25

Step 3: Add -81 to both sides.

x2+81+−81=−y2+18y+25+−81

x2=−y2+18y−56

Step 4: Take square root.

x=√−y2+18y−56 or x=−√−y2+18y−56

Answer:

x = 55

Step-by-step explanation:

Since 2 sides of the triangle are congruent, both 5, then the triangle is isosceles and the 2 base angles are congruent, both x , then

x + x + 70 = 180 ← sum of 3 angles = 180°

2x + 70 = 180 ( subtract 70 from both sides )

2x = 110 ( divide both sides by 2 )

x = 55

Answer:

55.52

Step-by-step explanation:

By sine rule:

[tex] \frac{ \sin x \degree}{5} = \frac{ \sin 70 \degree}{5.7} \\ \\ \sin x \degree = \frac{ 5 \: \sin 70 \degree}{5.7} \\ \\ \sin x \degree = \frac{ 5 \: \sin 70 \degree}{5.7} \\ \\ x \degree = {sin}^{ - 1} ( \frac{ 5 \: \sin 70 \degree}{5.7}) \\ \\ x \degree = 55.516753493 \degree\\ \\ x = 55.52[/tex]

Answer:

x = 20

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² = 12² + 16² = 144 + 256 = 400 ( take the square root of both sides )

x = [tex]\sqrt{400}[/tex] = 20

Answer:

3 hours 43 minutes

Answer:

3 hours and 43 minutes = 223 minutes

Step-by-step explanation:

Answer:

Please check the explanation.

Step-by-step explanation:

Part a)

Given that the two parallel lines are crossed by a transversal line.

Given that

m∠2 = 2x + 54 and m∠6 = 6x - 11

Angle ∠2 and ∠6 are corresponding angles.

Corresponding angles are congruent.

Thus,

m∠2 = m∠6

2x + 54 = 6x - 11

flipe the equation

6x - 11 = 2x + 54

subtract 2x from both sides

6x - 2x - 11 = 2x - 2x + 54

4x - 11 = 54

adding 11 to both sides

4x - 11 + 11 = 54 + 11

4x = 65

dvide both sides by 4

4x/4 = 65/4

x = 16.2500    (round to 4 decimal places)

Part b)

We have already determined

x = 16.2500

Given

m∠2 = 2x + 54

substitute x = 16.2500 in the euation

        = 2(16.2500) + 54

        = 86.5°

As angle ∠2 and angle ∠1 lie on a straight line. Hence, the sum of their angles must be 180°.

i.e.

m∠1 + m∠2 = 180°

substituting m∠2 =  86.5° in the equation

m∠1 + 86.5°  = 180°

subtracting 86.5° from both sides

m∠1 + 86.5° - 86.5° = 180° - 86.5°

m∠1 = 93.5°

Therefore, the measure of angle m∠1 is:

Answer: Monitor C is the different one.

Step-by-step explanation:

The aspect ratio is the relationship between width and height.

So we only need to see the quotients between width and height for each monitor and see which quotient is different.

Monitor A:  

Quotient = 1152/864 = 1.333....

Monitor B:

Quotient = 800/600 = 1.333...

Monitor C:

Quotient = 1920/1080 = 1.777...

Monitor D:

Quotient = 1600/1200 = 1.333...

We can see that the one with a different aspect ratio is monitor C.
