Answer:

third graph

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{1}{3}[/tex] x + 12 ← is in slope- intercept form

with slope m = [tex]\frac{1}{3}[/tex] and y- intercept c = 12

y = 3x + 4 ← is in slope- intercept form

with slope m = 3 and y- intercept c = 4

• If m > 0 , then graph slopes upwards from left to right

Both equations have a positive slope, thus both slope upwards from left to right.

the first equation has a y- intercept of 12

the second equation has a y- intercept of 4

Theses lines are represented in the third graph

The graph of x − 2 is a vertical line.

The graph of x − 2  is a straight line that is perfectly vertical, with no slope or angle. This line has an x-intercept of -2, meaning that the line crosses the x-axis at a point where x is equal to -2.

All points on the line have the same y-value, which is -2. This line extends infinitely in both directions and is a key example of a linear equation.

x − 2 is a linear equation, so its graph will be a straight line. In this case, the graph of x − 2 will be a vertical line that passes through the point (2, 0).

This is because when x is equal to 2, the equation will equal 0. As the x-value increases, the y-value will increase in a linear fashion, resulting in a vertical line.

The equivalent expression for given complex number i^55 is -i.

What are complex numbers?

Complex numbers are the numbers that are expressed in the form of a+ib where, a,b are real numbers and  ‘i’ is an imaginary number called “iota”. The value of i = (√-1). For example, 2+3i is a complex number, where 2 is a real number (Re) and 3i is an imaginary number (Im).

An imaginary number is usually represented by ‘i’ or ‘j’, which is equal to √-1. Therefore, the square of the imaginary number gives a negative value.

Since, i = √-1, so, i^2 = -1

Now,

complex number i^55=(i^4)^13(i^2*i)

=1^13(i^2*i)     (i^4=1)

=1(-1*i)             (i^2=-1)

Since the Pennsylvania lottery was rigged, the probability of drawing a 666 in the April 24th, 1980 drawing is 100%. The probability of drawing a 666 in the September 19th, 1980 Connecticut lottery, however, is extremely low, as it was not rigged and the odds of picking a specific 6-digit combination are 1 in 1 million.

To calculate this probability, you would take 1 divided by 1 million, which would be 0.000001. This means that the probability of drawing a 666 in the Connecticut lottery is 0.000001.   In conclusion, the probability of drawing a 666 in the April 24th, 1980 Pennsylvania lottery is 100%, while the probability of drawing a 666 in the September 19th, 1980 Connecticut lottery is 0.000001.

The study of mathematics comprises the study of quantities and their variations, equations and associated structures, shapes and their positions, and locations where they can be found. A combination of inputs and corresponding outputs are referred to as a "function," which describes the relationship between them. The term "function" refers to an association between inputs and outputs where each input produces a single, unique result. There are two domains, or scopes, assigned to each function. Usually, the symbol f is used to signify functions (x). input is an x. There are four basic categories of functions that are available: on functions, one-to-one functions, many-to-one functions, within functions, and on functions.

The polynomial functions f(x) = x³-2x²-3x+6

To solve this question, we use the factor theorem, and using it, the polynomial function is: f(x) = x³-2x²-3x+6

The factor theorem means that if k is a root of f(x), f(k) = 0.

Thus, applying the factor theorem for this question, we have to choose the function for which:

f(2) =0, f(√3) =0, f(-√3) = 0

Function 1:

f(x) = x³-2x²-3x+6

Testing the values:

f(2( = 2³-2(2)²-3(2) +6

= 8--6+9 = 0

f(√3) = √3³-2(√3)²-3√3 +6

=3√3-3√3 = 0

f(-√3) = -√3³-2(-√3)²-3(-√3) +6

What is rotation?

A rotation is a transformation that turns the figure in either a clockwise or counterclockwise direction. You can turn a figure 90°, a quarter turn, either clockwise or counterclockwise. When you spin the figure exactly halfway, you have rotated it 180°. Turning it all the way around rotates the figure 360°.

This question is solved by applying a 270° clockwise about the origin, which has the following rule:

(x, y) = (-y, x)

Coordinate Q:

At the Figure, coordinate Q is Q(-4, 5). Applying the rule:

(-4, 5) = (-5, -4)

So the image of Q is Q'(-5, -4).

Coordinate R:

In Figure, the coordinate R is R(-2, 5). Applying the rule:

(-2, 5) = (-5, -2)

So the image of R is R'(-5, -2).

Coordinate S:

At the Figure, coordinate S is S(-2, 9). Applying the rule:

(-2, 9) = (-9, -2)

So the image of S is S' (-9, -2)

Coordinate T:

At the Figure, coordinate T is T(-4, 9). Applying the rule:

(-4, 9) = (-9, -4)

So the image of T is T'(-9,-4).
