Answer:

13. x = 2 - 5y

14. x= 6y + 2

Answer is angle 2

Reason

two angles are adjacent angles when they share the common vertex and a side.

See attached picture

Answer:

Step-by-step explanation:

y - 1 = -9/2 (x + 7)

Distribute -9/2:

y - 1 = -9/2x - 63/2

Add 1 on both sides to isolate y:

(y - 1) + 1 = (-9/2x - 63/2) + 1

y = -9/2x -61/2

A line parallel to another has the same slope as that line so both slopes are -9/2.

M = -9/2

The shortest path between two points on the sphere is the arc of a great circle. Thus, option C is correct.

According to the statement

We have to find about the distance.

So, For this purpose, we know that the

The distance between two points is that the length of the path connecting them.

From the given information:

We have to search out that the the shortest distance between two points on a sphere.

Then we all know that the

Sphere is that the set of all points in three-dimensional space lying the identical distance from a given point, or the results of rotating a circle about one in every of its diameters.

Then

The shortest path between two points on the sphere is that the arc of a good circle.

According to this the option C is correct.

So, The shortest path between two points on the sphere is the arc of a great circle. Thus, option C is correct.

Receipts represents income to the company. It is a source of cash inflow. Expenses represents cash outflow. Net cash flow is the difference between receipts and expenses. Cumulate balance is the sum of the net cash flow of the previous periods and the net cash flow of the present period.

A = Net cash flow + expenses

1975 + 125 = 2100

B = Receipts - expense

$2225 - $1925 = $300

C =  Receipts - expense

$2050 - $2000 = $50

D = Net cash flow = $270

E = cumulative balance in April + net cash flow in May

when we take x = 9.33, the equation becomes true, which means that the linear equation has one solution.

Here we have the following linear equation:

15 + 3*(2x - 9) = 44

And we want to see if this has a solution, it means that there is a value of x such that the equation becomes true. Let's see that.

To do it, we need to isolate the variable, x, in one of the sides of the equation.

Expanding the product we get:

15 + 3*2x - 3*9 = 44

Moving the terms without x to the right side:

15 + 6x - 27 = 44

6x = 44 + 27 - 15 = 56

Now we can divide both sides by 6 so we get:

x = 56/6 = 9.33

So, when we take x = 9.33, the equation becomes true, which means that the linear equation has one solution.

Time is the continuous flow of existence and the events that take place in what appears to be an unbreakable sequence from the past, present, and forward into the future. Time is often referred to be a fourth spatial dimension in addition to the three others.

Philosophers, theologians, and scientists have long considered time to be an important subject of study, but they have never been able to agree on a definition of time that can be used across all of these fields without becoming circular.

The expression represents the perimeter, in centimeters, of the rectangle is P = 30q + 2p

The formula for calculating the perimeter of a rectangle is expressed as:

P = 2(l+w)

l = (7p+8q) cm

w =  (10p - 9q) cm

Substitute

P = 2(7p+8q+10p-9q)

P = 2(15q+p)

P = 30q + 2p

113 with a remainder of 3

Step-by-step explanation:

The order of the points starting with a and going clockwise around the circle is;

a ⇒ c ⇒d ⇒b

Here,

Four points, a, b, c, and d, lie on a circle having a circumference of 17 units.

b is 5 units counterclockwise from a.

c is 3 units clockwise from a.

d is 11 units clockwise from a and 6 units counterclockwise from a.

We have to find, The order of the points starting with a and going clockwise around the circle.

What is Circumference of circle?

The circumference is the distance around a circle or any curved geometrical shape.

Now,

b is 5 units counterclockwise from a.

b ⇒ a

c is 3 units clockwise from a.

b ⇒ a ⇒ c

d is 11 units clockwise from a and 6 units counterclockwise from a.

d ⇒ b ⇒a ⇒ c ⇒d

The three inequalities that satisfies all the points in the unshaded region of the graph of inequalities are;

The three inequalities that satisfies all the points in the unshaded region are;

1) The inequality that represents the unshaded region to the left of the vertical dashed line at x = 5 is found as follows;

A region to the left of a vertical dashed line in inequality is represented by the less than or equal to symbol, ≤. The region to the right is represented by ≥

The region to the left of the dashed line, x = 5 is therefore;

2) The region located below the dashed line y = 10 is represented by the inequality;

3) The slope, m, of the dashed line that extends from point (0, 10) to point (5, 0) is given by the equation;

m = (0 - 10)/(5 - 0) = -2

The equation of the line is therefore;

y - 0 = -2 × (x - 5) = -2•x + 10

y = -2•x + 10

Which gives;

y + 2•x = 10

2•x + y = 10

The inequality that represents the region to the right of the line 2•x + y = 10 is therefore;

2•x + y ≥ 10

Using translation concepts, the series of transformations that shows that pentagon A is congruent to pentagon B is:

B. Rotate pentagon A 90° clockwise about the point (1, 1), reflect it over the x-axis, and translate it 3 units to the left.

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

In this problem, we have that the Pentagons have different orientations, meaning that it was rotated, eliminating options A and D.

For the vertices to reach the position they reached in Pentagon B, there had to be a shift left, and before the shift left, the Pentagon must have been entirely at the fourth quadrant, meaning that it was reflected about the point (1,1), and option B is correct.
