The table represents the direct relationship y = - 3 · x. (Correct choice: C)

Two variables have a direct relationship if and only if the following model is observed:

y ∝ x

y = k · x

Where k is the constant of proportionality.

The table may represent a direct relationship if and only if each ordered pair has the same constant of proportionality. Now we proceed to evaluate the table:

k₁ = - 3 / 1

k₁ = - 3

k₂ = - 9 / 3

k₂ = - 3

k₃ = - 15 / 5

k₃ = - 3

As k₁ = k₂ = k₃, then the table represents the direct relationship y = - 3 · x.

System of equation are,

9x + 3y + 12z = $45.75

5x + 6y + 8z = $41.50

12x + 4y + 50z = $128

Where, x is number of boxes of pencil,

           y is number of boxes of markers.

           z is number of packages of notebook paper.

What is System of equation?

System of equation is two or more equations to be solved together. For a system to have a unique solution, the number of equations must equal the number of unknowns.

Now, Let number of boxes of pencil = x

The third term of a given geometric sequence based on common ratio 2 is 8.

A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.

Given a geometric sequence.

First term = 2

Second term = 4

Common ratio = Next term / previous term

Common ratio = 4/2 = 2

So,

Common ratio = Third term / second term

The third term = common ratio × second term

The third b = 2 × 4 = 8

Average cost of a gallon of gas in Texas in 2013 was $3.42.

Given,

Average cost of a gallon of gas in Texas in 2010 = $2.53

From 2010 to 2013 average cost of regular gasoline in Texas increased by 35%

We have to find the average cost of a gallon of gas in Texas in 2013:

= Average cost in 2010 × (135/100)

= 2.53 × (135/100)

= 2.53 × 1.35

Based on the alternate exterior angle theorem, if m<1 = m<2, the statement which is true is that: B. n || m.

Parallel lines can be defined as two (2) lines that are always the same (equal) distance apart and never meet.

The alternate exterior angle theorem states that when two (2) parallel lines are cut through by a transversal, the alternate exterior angles that are formed are congruent or angles of equal measure.

In this context, we can reasonably infer and logically deduce that the true statement which best proves that lines n and m are parallel is that angle 1 is congruent to angle 2 because by definition, all alternate exterior angles are congruent, if two (2) parallel lines are cut by a transversal.

The process of breaking or decomposing an entity (such as a number, a matrix, or a polynomial) into a product of another entity, or factors, whose multiplication results in the original number, matrix, etc., is known as factorisation or factoring.

According to the given value;

The prime factorisation of 20 = 2 x 2 x 5 = 2 2 x 5

Thus, here we can see, 20 is not a perfect square, because we cannot pair digit 5 after factoring 20.

By using the fact that the two lines with the purple arrow are parallel, We can conclude that the angles are y = 133° and x = 47°

First,  notice that the two lines with the purple arrow are parallel lines, and these lines are intersected by the same line, then the 4 angles formed in the above line are the same ones than in the below line.

So, if the angle in the fourth quadrant of the above intersection is the same as the angle in the fourth quadrant of the below intersection, then we can see that:

y = 133°

And x + y should be equal to 180°, then:

133° + x = 180°

x = 180° - 133° = 47°

We can conclude that the angles are y = 133° and x = 47°
