Answer:
x = 16.
Explanation:
The angels x and 164 are supplementary, meaning they add up to 180; therefore, we can say
[tex]x+164^o=180^o[/tex]Subtracting 164 from both sides gives
[tex]x+164^o-164^o=180^o-164^o[/tex][tex]x=16^o\text{.}[/tex]Hence, the value of x is 16 degrees.

If a triangle ABC is at: A = (10, 7) B = (4, -4) C= (- 11, -9) and if it is translated right 2 and down 7, find the new point B'
Answers
B' (6, -11)
Explanations:
Translations is a transformation technique used to change the position of an object in an xy-plane.
Given the coordinate of a triangle ABC given as A (10, 7) B (4, -4) C (- 11, -9). If it is translated right 2 and down 7, the translation rule will be;
(x, y) -> (x+2, y-7)
Determine the new point B'
B' = (4+2, -4-7)
B' = (6, -11)
Therefore the coordinate of the new point B' is (6, -11)
is the prime factorization of what composite number?
Answers
A factor of a number is called a prime factor.
The prime factor of a number is obtained by a factor tree method or by a division method.
The expression of a given number as a product of factors is called prime factorisation.
The prime number has 1 and the number itself is a factor.
The composite number will have more than one factor.
A number which is not a prime number is a composite.
1 and the number itself are not included in the prime factorisation of a composite number.
let us take the example
For the number 20, the prime factors are 2*2*5.
The above example is an example of the prime factorization of the composite number. where 1 and the number itself are not included in the prime factorisation of a composite number.

Answers
The general equation of a line is:
[tex]y=m\cdot x+b[/tex]Where m is the slope of the line and b its the value of the y-intercept of the line.
Q) The question asks about the equation of a graphed line.
A) In order to find the equation of the line, we note that it passes through the points:
[tex]\begin{gathered} (x_1,y_1)=(0,-2) \\ (x_2,y_2)=(4,-1) \end{gathered}[/tex]The first point give us the value of the y-intercept of the line (b), so the y-intercept is y = -2, and we have:
[tex]b=-2[/tex]Now we must calculate the slope (m) of the line. In general the slope of a line is given by the following formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]Where (x1,y1) and (x2,y2) are the coordinates of two points of the line. Using the points of above and the last formula we find that:
[tex]m=\frac{y_2-y_1}{x_2-x_1}=\frac{-1-(-2)}{4-0}=\frac{2-1}{4}=\frac{1}{4}[/tex]Answer
Using the values of m and b, and the general equation, we find that the equation of the line is:
[tex]y=m\cdot x+b=\frac{1}{4}x-2[/tex]Or: y = 1/4 x - 2
So the correct option is option number 3.

First you will answer some questions below to find the correct coordinates to use for your graph. In part H, you will create the graph using this spreadsheet.Part AThe starting coordinates of the graph will be (0, 0), or the origin. This point represents Kiley’s house. From here, if you drew a line segment that represents Kiley’s car ride from her house to the airport, at what point would the line segment end?
Answers
We want to draw a graph with a y-axis equal to the distance from Kiley's home, and the x-axis represents the amount of time the trip will take. Then, each point point on this graph represent a location. Since our origin(0, 0) is Kiley's house, if we drew a line segment that represents Kiley’s car ride from her house to the airport, this line would end at the location of the airport, the y-axis would inform how far is the airport and the x-axis how much time it is needed to get there.
Since Kiley drove 24.3 miles from their house to the airport in 1/2 hour, this means the end of this line will be at (0.5, 24.3).
What is the simple interest on $4000 principal at 5% for 3/4 years
Answers
Answer:
$150
Explanation:
The simple interest can be calculated using the following equation
I = Prt
Where P is the principal, r is the rate as a decimal and t is the number of years.
So, replacing P = $4000, r = 5% = 0.05 and t = 3/4 years, we get:
I = ($4000)(0.05)(3/4)
I = $150
Therefore, the simple interest is $150

The exact value of the cosine of the subtraction of angles is equal to - 3 / 5. (Correct choice: A)
How to determine the exact value of a trigonometric expression
In this problem we find the exact value of the sine of an angle set in the third quadrant and the exact value of the cosine of an angle set in the fourth quadrant. Herein we need to determine the cosine of subtraction of two angles:
cos (u - v) = cos u · cos v + sin u · sin v
First, determine the missing cosines and sines by the fundamental trigonometric formula:
cos u < 0, sin v < 0
cos u = - √(1 - sin² u)
cos u = - √[1 - (- 7 / 25)²]
cos u = - 24 / 25
sin v = - √(1 - cos² v)
sin v = - √[1 - (12 / 15)²]
sin v = - 3 / 5
Second, determine the exact value of the trigonometric equation:
cos (u - v) = (- 24 / 25) · (12 / 15) + (- 7 / 25) · (- 3 / 5)
cos (u - v) = - 3 / 5

Answers
The transformation that changes the area of a shape is dilation (Option D)
Step by step explanation
Option A: Translation
A translation is a geometric transformation that moves every point of a figure, shape, or space by the same distance in a given direction. For this type, the image is congruent with the original shape.
Option B: Rotation
A rotation is a type of transformation that takes each point in a figure and rotates it a certain number of degrees around a given point. For this type, the image is congruent with the original shape.
Option C: Reflection
A reflection is a transformation where each point in a shape appears at an equal distance on the opposite side of a given line - the line of reflection. For this type, the image is congruent with the original shape.
Option D: Dilations
Dilation in math is a transformation that changes the size of a figure so it becomes larger or smaller without changing shape. This type changes the area since the area is the size of a figure.

Answers
Answer:

Explanation:
The number of minutes Diamond spends singing = s
The number of minutes she spends dancing =d
Since she spends a total of 45 minutes singing
• s+d=45
Since she spends 20 minutes of her time singing.
• s=20 minutes
Substitution into: s+d=45
[tex]\begin{gathered} 20+d=45 \\ d=45-20=25 \end{gathered}[/tex][tex]\text{Rate}=\frac{Number\text{ of calories burned}}{Time}[/tex]The number of calories burned = Time X Rate
