Use the Distributive Property to determine which of the following statements is equivalent to 4(8 – 1).

James defines that an angle is a figure consisting of two rays.

The statement of James is not precise enough because he should specify that the rays must be collinear.

The two rays coming from the same point will form collinear rays which will form an angle at the end point. The common end point is the vertex of the angle. And each ray will known as an arm of an angle.

From the figure, we can see that the vertex is the corner of the angle, i.e.,  O is the vertex in the given figure.

OA and OB are the two arms of the angle. The line OB is also known as reference line which is the line where an angle is drawn.

Also, the line OA will be considered as terminal line. Terminal line is the side up to which an angle measurement done.

Answer:

y=x+6

Step-by-step explanation:

First, write out the slope intercept equation.

y=mx+b

Ok, the first step for finding a linear equation is finding the y-intercept. The line crosses the y-axis at 6, so the y-intercept is 6. Plug that into the slope-intercept Equation:

y=mx+6

Then, slope is rise over run, and the line goes up 1 and right 1 to get to the next point, so divide those numbers.

1/1=1

Then plug that into your slope intercept equation:

y=1x+6

Since the one won't do anything, it will just be this:

y=x+6

The equations of each line are:

a. y = -3x + 3

b. y = -2/3x - 3

In slope-intercept form, the equation of a line is written as, y = mx + b, given that:

Note: the slope values of parallel lines are the same.

a. The slope of y = -3x - 1 is, -3. The line that is parallel to it will have the same slope (m) of -3.

Substitute m = -3 and (x, y) = (2, -3) into y = mx + b to find b:

-3 = -3(2) + b

-3 = -6 + b

-3 + 6 = b

3 = b

b = 3

Substitute b = 3 and m = -3 into y = mx + b

y = -3x + 3

b. Rewrite 2x + 3y = 6 in the slope-intercept form

3y = -2x + 6

y = -2/3y + 2

The slope of y = -2/3y + 2 is, -2/3. The line that is parallel to it will have the same slope (m) of -2/3.

Substitute m = -2/3 and (x, y) = (0, 5) into y = mx + b to find b:

5 = -2/3(0) + b

-3 = 0 + b

-3 = b

b = -3

The probability of getting no. less than 11  after 1 spin is  0.833 .

An experiment is a situation involving chance or probability that leads to results called outcomes.

An outcome is the result of a single trial of an experiment.

An event is one or more outcomes of an experiment.

Probability is the measure of how likely an event is.

P(A) = The Number Of Ways Event A Can Occur /(The total number Of Possible Outcomes).

The probability of an event depends on the number of favorable (occurrence of the desired event) outcomes in comparison to the total number of outcomes.

We define the probability of an event by dividing the favorable outcomes by the total number of outcomes, as shown below.

P = n(E) / n(S)

Where,

n(E) = The favorable number of outcomes

n(S) = The total outcomes

Given Data:

The spinner rotates 1 time

find the probability of getting P(number> 11) from numbers 1 to 12.

n(E) =  10

n(S) = 12

P(A) = 10 /12

The width of the rectangle, w, is: 19 inches.

The perimeter of a rectangle is the sum of all its four sides which is calculated using the formula:

Perimeter = 2(length + width).

Given:

Perimeter = 144 inches

Width = w inches

Length = 3w - 4 inches

Thus:

2(3w - 4 + w) = 144

2(4w - 4) = 144

8w - 8 = 144

8w = 144 + 8

8w = 152

8w/8 = 152/8

w = 19

Answer: 30

Step-by-step explanation:

Slope: y/x

y/x =

+60/+2=

60/2=30

Answer: We have m = −3/2 as the slope and b = 150 as the y-intercept.

Step-by-step explanation:

Given data,

The slope of the following line 3x+2y=300

Define Slope :

Slope = (Change in height)/(Change in width) Or: Slope = rise/run. If y represents the vertical direction on a graph, and x represents the horizontal direction, then this formula becomes: Slope = (Change in y)/(Change in x)

The equation of a line presents the relationship between the components of a line in a certain coordinate system. To construct the equation of the line, we must take note of the parameters such as the slope, a point at which the line passes through, and the intercepts.

We solve for the slope, m, and the y-intercept, b, for the given line. We do this by rewriting the expression into the slope-intercept form,

                                y = mx + b

We proceed with isolating y in the given equation.

                                3x + 2y = 300

                                 2y = - 3x + 300

                                  y = (-3x + 300) / 2

                                  y = (-3/2) x + 300/2

                                  y = (-3/2) x + 150

Therefore, we have m = −3/2 as the slope and b = 150 as the y-intercept.

So, slope = -3/2

      b = 150

So, For this purpose, we know that the

A Rectangle may be a four sided-polygon, having all the interior angles adequate 90 degrees.

From the given information:The length of a rectangle is 3 ft but double the width, and therefore the area of the rectangle is 44.

Then

The formula for the world of a rectangle may well be a = L(length) × W(width)A = L × W

Plug in the information:A = 44, L = 2W - 3

b/c but means switch the order before subtracting, W = W

44 = (2W - 3)×W

44 = 2W² - 3W

And then

2W² - 3W - 44 = 0

so,

Factoring: (2W - 11)(W + 4) = 0

2W - 11 = 0 solves to W = 5.5

W + 4 = 0 solves to W = -4

So W = 5.5 and L = 2(5.5) - 3 = 8.

Taking into account the definition of a system of linear equations, the speed of the first train is 363 mph and the speed of the second train is 356.8 mph.

A system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.

Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied. In other words, the values ​​of the unknowns must be sought, with which when replacing, they must give the solution proposed in both equations.

In this case, a system of linear equations must be proposed taking into account that:

So, the system of equations to be solved is

[tex]\left \{ {{F+S=719.8} \atop {F=S+6.2}} \right.[/tex]

It is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.

In this case, substituting the second equation in the first one you get:

S + 6.2 + S= 719.8

Solving:

2S + 6.2= 719.8

2S= 719.8 - 6.2

2S= 713.6

S= 713.6÷ 2

S= 356.8

Remembering that F= S+ 6.2, then:

F= 356.8 + 6.2

F= 363
