4x ➡️ 4(35) = 140
10 degrees is already known
Step by step
The angles are x and 3x and 2x and 4x and 10 degrees, they form a complete circle equal to 360 degrees. So our equation to solve
x + 3x + 2x + 4x + 10 = 360
Combine like terms
10x + 10 = 360
Subtract 10 from both sides to isolate x
10x +10 -10 = 360 -10
Combine like terms
10x = 350
Divide by 10 to solve for x
x = 35
Now we use the expressions for each angle and substitute value of x (35) for x
x ➡️ = 35
3x ➡️ 3(35) = 105
2x ➡️ 2(35) = 70
4x ➡️ 4(35) = 140
10 degrees is already known
See the attachment for degrees of each angle

Q18: x = 21, y = 15
Q19: x = 16, y = 10
Q20: x = 24, y = 19
Step-by-step explanation:
Q18:
(3x - 16) + (6x + 7) = 180 (corresponding angles, sum of angles on a straight line=180°)
9x - 9 = 180
9x = 189
x = 21
11y - 32 = 6x + 7 (vertically opposite angles)
11y - 32 = 6(21) + 7
11y - 32 = 133
11y = 165
y = 15
Q19:
8x - 14 = 5x + 34 (corresponding angles, vertically opposite angles)
3x = 48
x = 16
(8x - 14) + (5y + 16) = 180 (sum of angles on a straight line=180°)
8(16)-14 + (5y + 16) = 180
114 + 5y + 16 = 180
5y + 130 = 180
5y = 50
y = 10
Q20:
47 + 3x + (2x + 13) = 180 (corresponding angles, sum of angles on a straight line=180°)
5x + 60 = 180
5x = 120
x = 24
5y - 23 = 3x (corresponding angles)
5y - 23 = 3(24)
5y - 23 = 72
5y = 95
y = 19
XYZ has coordinates X(2, 3), Y(1, 4), and Z(8, 9). A translation maps X to X′(4, 8). What are the coordinates for Z′? *
Answers
Answer:
Z'(10, 14)
Explanation:
Taking into accoun that the vertex point X(2, 3) is mapped to X'(4, 8), we can say that the translation rule is:
(a, b) ----> (a + 2, b + 5)
Because
X(2, 3) ----> (2 + 2, 3 + 5)
----> X'(4, 8)
So, using this rule, we can find the coordinates for Z' as:
Z(8, 9) ----> (8 + 2, 9 + 5)
----> Z'(10, 14)
Therefore, the answer is Z'(10, 14)

6. Create a systems of inequalities to represent the graph below
Answers
System of inequalities
We are given the graph where two lines represent the solution of a system of inequalities.
The solution is the double-shaded region of the graph.
We need to find the equation of the blue line and the red line and then convert them to inequalities.
Let's start with the blue line. We need to find two clear points through which it passes. These are (0,6) and (2,0). Now we write the equation of the line when knowing two points (the point-point form):
[tex]\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex][tex]\begin{gathered} \displaystyle y-6=\frac{0-6}{2-0}(x-0)=-3x \\ \text{Adding 6:} \\ y=-3x+6 \end{gathered}[/tex]For the red line, the points are (0,0) and (2,2):
[tex]\begin{gathered} y-0=\frac{2-0}{2-0}(x-0)=x \\ y=x \end{gathered}[/tex]Now we have the equations of the lines, we must convert the equation to inequality by inserting one of these symbols instead of the equal sign:
> ≥ < ≤
For the blue line, the equation of the line is:
y = -3x + 6
Testing the origin (0,0):
0 = 0 + 6
0 = 6
To convert this to a true inequality we must replace the = for < or ≤
Since the blue line is solid, the points on the line belong to the solution, thus the first inequality is:
y ≤ -3x + 6
Now for the red line. The equation is
y = x. Let's test the point (2,1)
1 = 2
We must use the sign ≤ to make the expression true, thus the second inequality is:
y ≤ x
Thus, the system of inequalities is:
y ≤ -3x + 6
y ≤ x

The rates of changes of the given function for the corresponding intervals are: [-5, -1] = -8, [-4, -1] = -7, [-3, -1] = -6, [-2, -1] = -5.
What is function?
A function, according to a technical definition, is a relationship between a set of inputs and a set of potential outputs, where each input is connected to precisely one output.
This means that a function f will map an object x to exactly one object f(x) in the set of potential outputs if the object x is in the set of inputs (referred to as the domain) (called the codomain).
The rate of change of a function can be calculate using the formula:
[tex]R = \frac{f(x_2)-f(x_1)}{x_2-x_1}[/tex]
Putting the value from the question:
given [x₁, x₂] = [-5, -1]
f(-5) = 35 , f(-1) = 3
Putting these value in formula:
[tex]R = \frac{3-35}{-1 -(-5)}[/tex]
R = -32/4
R = -8
given [x₁, x₂] = [-4, -1]
f(-4) = 24, f(-1) = 3
Putting these value in formula:
[tex]R = \frac{3-24}{-1 -(-4)}[/tex]
R = -21/3
R = -7
given [x₁, x₂] = [-3, -1]
f(-3) = 15, f(-1) = 3
Putting these value in formula:
[tex]R = \frac{3-15}{-1 -(-3)}[/tex]
R = -12/2
R = -6
given [x₁, x₂] = [-2, -1]
f(-2) = 8, f(-1) = 3

Answers
Let's begin with what we know:
For an ordered pair, we have (independent variable, dependent variable)
For example, when x is the independent variable & y is the dependent variable, we have (x, y)
y = f(x)
We are to write a short statement that expresses a possible relationship between the variables below:
1. (volume of a gas tank, cost to fill the tank)
Volume of gas is the independent variable & Cost to fill the tank is the independent variable. That means that:
As the volume of the gas tank increases. the cost of filling it increases. Once the volume of the gas tank is filled, the cost to fill the tank is at its maximum
2. (time, price of a Ford sedan), where time represents years from 1975 to 2017

As the time lapses from 1975 to 2017, the price of the Ford sedan depreciates/reduces.
The sum of three palm tree heights range from 32 to 42 feet. The height of two of the trees are 8 feet and 16 feet. If the height of the third tree is x feet, write and solve a compound inequality to show the possible heights of the third tree.
Answers
The inequality to show the possible heights of the third tree is 8 ≤ x ≤ 18.
How to calculate the value?Inequalities are created through the connection of two expressions. It should be noted that two expressions in an inequality aren't always equal. They are denoted by the symbols ≥ < > ≤
Let the height of the third tree be x.
By the given condition, this will be:
8 + 16 + x ≥ 32 and 8 + 16 + x ≤ 42
The first relation will give x ≥ 32 - 24 = x ≥ 8
The second relation will give:
8 + 16 + x ≤ 42
24 + x ≤ 42
x ≤ 42 - 24
x ≤ 18
The inequality is 8 ≤ x ≤ 18.

If sum of three palm tree heights range from 32 to 42 feet. The height of two of the trees are 8 feet and 16 feet. If the height of the third tree is x feet. Then compound inequality is 8 ≤ x ≤ 18.
What is Inequality?A relationship between two expressions or values that are not equal to each other is called 'inequality.
Let height of the third tree be x.
By the given condition
The sum of three palm tree heights range from 32 to 42 feet
8 + 16 + x ≥ 32 and 8 + 16 + x ≤ 42
Solve these inequalities
8 + 16 + x ≥ 32
24+x ≥ 32
x≥ 32-24
x≥ 8
and 8 + 16 + x ≤ 42
24+ x ≤ 42
x≤ 42-24
x ≤ 18
Hence the inequality is 8 ≤ x ≤ 18.

Answers
Using the percentage of guests choose one option for their dinner , the number of guest chose meat as their dinner option are 455.
As given in the question,
Options given for dinner :
Meat, Fish and Vegetarian
Percent of guest having
Meat in dinner = 65%
Vegetarian = 5%
Number of guest chose fish =210
Percent of guest chose fish = 100 -(65 +5)
= 30%
Let x be the total number of guest
30% of x = 210
⇒ (30/100) × x = 210
⇒ x= (210 ×100) / 30
⇒ x = 700
Therefore, using the percentage of guests choose one option for their dinner ,the number of guest chose meat as their dinner option are 455.
