The system of equations involving 1/3x - 3y = -4 and x - 9y = -12 has infinite number of solutions.

A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.

There are three methods that can be used to solve system of linear equations.

1. Elimination

2. Substitution

3. Graphing

Using substitution method, given two linear equations in x and y,

1/3x - 3y = -4     (equation 1)

x - 9y = -12     (equation 2)

Using the second equation, find the value of one variable, lets say x, in terms of the other.

x - 9y = -12     (equation 2)

x = 9y - 12

Substitute the equation of x to the first equation.

1/3x - 3y = -4     (equation 1)

1/3(9y - 12) -3y = -4

3y - 4 - 3y = -4

Combining the all terms containing the variable y on one side and the constants on the other side of the equality, and solving for y.

3y - 3y = -4 + 4

0 = 0

Since we did not get unique values for x and y, check if one of the equations is a simplified form of the other. Multiply the first equation with 3.

1/3x - 3y = -4     (equation 1)

3(1/3x - 3y) = 3(-4)

x - 9y = -12

Since this new equation is the same with the second equation, this means that the lines of the two equations are the same(overlapping). Hence, the system of equations has infinite number of solutions.

The area left to be tiled on Wednesday is 1/6

Let the total area to tile be 60 sq feet

We have taken 60 sq feet as the LCM of 2 and 3 is 6. So taking up 60 makes our calculation part easy.

Area tiled on Monday = 1/3*60 = 20 sq feet

Area tiled on Tuesday = 1/2*60 = 30 sq feet

Area remaining to be tiled = 10 sq feet

So, a fraction of the area left to be tiled = Area left to be tiled/Total area to be tiled

= 10/60 = 1/6

Hence, 1/6 of the area is left to be tiled

It depends on the sign of [tex]x-4[/tex].

Recall the absolute value function's definition:

[tex]|x| = \begin{cases}x & \text{if } x \ge 0 \\ -x & \text{if } x < 0\end{cases}[/tex]

Now, if [tex]x-4\ge0[/tex], then

[tex](x-4)|x-4| = (x-4)(x-4) = x^2 - 8x + 16[/tex]

On the other hand, if [tex]x-4<0[/tex], then

[tex](x-4)|x-4| = -(x-4)(x-4) = -(x-4)^2 = -x^2 + 8x - 16[/tex]

What you first suggested is incorrect. We have

[tex]x^2 - 16 = (x - 4) (x + 4)[/tex]

but [tex]|x-4| \neq x + 4[/tex].

We can show this using the definition again. If [tex]x-4\ge0[/tex], then

[tex]x-4 = x+4 \implies -4=4[/tex]

which is a contradiction; on the other hand, if [tex]x-4<0[/tex], then

[tex]-x+4 = x+4 \implies 2x = 0 \implies x =0[/tex]

holds for only one value of [tex]x[/tex].

Step-by-step explanation:

The value of A - B is - 12

It is given that A + B = 0 .......... ( Eq . 1 )

⇒ A = - B ............ ( i )

Another equation which is given is :

AB  = - 36 ........... ( Eq . 2 )

Using (i) in Eq . 2

- B ( B ) = -  36

- B ² = - 36

B ² = 36

B  = √ 36

B = 6 .......( ii )

Using B = 6 in ( i ) ,

A B = - 36

A ( 6 ) = - 36

A = -6

This implies,  A = - 6 and B = 6

Now to find the value of A - B , we need to put the values

A - B = - 6 - 6

=  - 12

Hence, the value of A - B is - 12 .

According to the given statement Outliers would be any sightings that are more than 1.5 IQR below Q1 or more then 1.5 IQR above Q3.

An outlier is a value that is significantly different from the other values in a random sampling of a population. In some ways, this definition leaves it up towards the analyst (or a consensus process) to determine what is abnormal.

Identifying potential outliers is critical for such following reasons. An outlier could imply faulty data. For example, the data could have been wrongly coded, or an experiment could have been done erroneously.

An outlier is defined as an observation that is less than or more than Q3 times IQR.

We need to look for place variances in Q1 and Q3.

When we utilize the IQR approach to discover outliers outside of Q1 and Q3, we create a "fence." Outliers are any values that fall outside of the defined boundary.

To construct this fence, we take 1.5 times the IQR, deduct it from Q1, and add it to Q3.

IQR = (1.5 - Q1)

IQR = (1.5 + Q3)

This provides us with the minimum and maximum fence posts to which we can compare every observation.

The odds against exactly 5 cars passing over the bridge in that time is calculated as 4:21

A probability must be between 0 and 1 (nothing can happen with a greater than 100% likelihood). The chances are not as limited. Odds can be any positive number; for example, a chance of 2/3 is equivalent to odds of 2/1. By simply dividing the favorable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula.

By dividing the odds in the first group by the odds in the second group, the odds ratio is calculated. For many clinicians, odds and odds ratios are difficult to comprehend. Odds are calculated by dividing the likelihood of an event happening by the probability that it won't.

Distance can be defined as the amount of ground covered or walked by a physical object, regardless of its direction, starting or ending point.

In order to determine the total distance walked by this person, we would simply add each of the distances recorded together as follows:

Total distance = 3 + 7 + 4 + 5 + 4

Total distance = 23 miles.

In order to determine the total displacement vector, we would add all of the vectors together as follows:

3 miles East = <5, 0>

7 miles Southeast = <7/√2, -7/√2> or <7cos45°, -7sin45°>

4 miles South = <0, -4>

5 miles Southwest = <-5/√2, -5/√2> or <-5cos45°, -5sin45°>

4 miles East = <4, 0>

Total displacement vector = <5 + 7/√2 + 0 - 5/√2 + 4, 0 - 7/√2 - 4 - 5/√2 + 0>

Total displacement vector = <9 + 2/√2, -4 - 12/√2>

Total displacement vector = <9 + 1.41, -4 - 8.49>

Total displacement vector = 10.41i - 12.49.

If this person walked straight home, the total distance walked is giving by  the resultant of the above displacement vector:

Total distance = √[10.41² + (-12.49)²]

Total distance = √[108.37 + 156.00]

Total distance = √264.37

Total distance = 16.26 miles.

The other three sides of the patio will be represented by one line with a slope of 2/3 and two lines with a slope of  -3/2.

The general equation of a straight line is -

y = mx + c

Given in the question is a equation that describes the one side of a rectangular patio. From the question, we can write -

Equation representing a side of Patio - y = 2/3x + 5/3

If we compare the equation representing a side of Patio with the general equation of line, we get -

y = 2/3 x + 5/3      

[y] = [m] x + [c]

From this we can conclude that -

m = 2/3 = slope of line

c = 5/3 = y - intercept

The patio is in the shape of a rectangle. Therefore, the side opposite to the line of slope → 2/3 will be equal in length and parallel to it. We know, that the slope of two parallel lines are same. So, the slope of line parallel to  y = 2/3x + 5/3  will be 2/3.

The remaining two sides are perpendicular to both the side of slope → 2/3. The remaining sides are also parallel to each other, indicating they both have same slope. The slope of a line perpendicular to a given line (L) is given by -

m [p] x m [L] = -1

m [p] = - 1 / m [L]

m [p] = - 3/2

Therefore, the remaining two sides will have slope of  -3/2.

Therefore, the other three sides of the patio will be represented by one line with a slope of 2/3 and two lines with a slope of  -3/2.

The given statement is True.

"It is not always helpful to rewrite an equation in standard form as a first step in solving it."

In standard form, the right side of an equation should be 0 and every component on the left side should be 1. For example, x2 = 4; to express this in standard form, move the number 4 to the left side of the equation, resulting in x2 - 4 = 0.

If you are asked to find x in this circumstance, there is no need to write the equation in standard form; simply take this same real number of both of the equation's sides to find x.

Ax+By=C is the common structure for linear equations in two variables. 2x+3y=5, for example, is a simple linear equation. It is rather simple to find both intercepted communications when an equation is stated in this way (x and y). This form is indeed useful for solving two-linear equation systems.
