Answer:
x = 2
Step-by-step explanation:
Given equation,
→ 4x - 22 = -14
Now the value of x will be,
→ 4x - 22 = -14
→ 4x = -14 + 22
→ 4x = 8
→ x = 8/4
→ [ x = 2 ]
Hence, the value of x is 2.

Question 1 options: James is observing the population of the fish he put into a pond. He built a pond and populated it with 900 fish. The population of the fish doubles every year.
The equation by using x represent the number of years and y represent the number of fish is y=900×(2)ˣ.
Given that,
James is keeping an eye on the fish population in the pond he created. He constructed a pond and added 900 fish to it. Every year, the fish population doubles.
We have to find the equation by using x represent the number of years and y represent the number of fish.
We know that,
We get
Number of fish at starting =900
Number of fish after 1 year =900×2=1800
Number of fish after 2 year =1800×2=3600=900×(2)²
Number of fish after 3 year =3600×2=7200=900×(2)³
So,
Here we can see that the number of fish are in Geometric progression (G.P) with a=900 and r=2
So,
Tₙ=arⁿ⁻¹
We get
y=900×(2)ˣ
Therefore, The equation by using x represent the number of years and y represent the number of fish is y=900×(2)ˣ.

The inequality which represents the range of temperature at which water boils is 100 ≤ b thus, option (C) is correct.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.
As per the given,
Water boils at a minimum temperature of 100 degrees Celsius.

What is an expression?
Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows: Expression: (Math Operator, Number/Variable, Math Operator)
Given that
the number of yellow tile in figure 1 is 8.
The number of yellow tile in figure 2 is 12.
The number of yellow tile in figure 3 is 16.
(a) The table is
Figure 1 2 3
Number of tiles 8 12 16
(b)
The number of tiles increase at a constant rate.
The rate is (12 - 8) = (16 - 12) = 4
The relation with the figure and number of tiles is
The number of tiles is = 4 + (the number of figure - 1)4
C)
Assume that y represents total number of tiles.
x = Number of figure
Rewrite "The number of tiles is = 4 + (the number of figure - 1)4" in term of x and y:
y = 8 +(x - 1)4
y = 8 + 4x -4
y = 4x + 4
d) Putting x = 24 in y = 4x + 4
y = 4×24 + 4
y = 96 + 4
y = 100
e)
Putting y = 176 in y = 4x + 4
176 = 4x + 4
Subtract 4 from both sides:
172 = 4x
Divide both sides by 4
x = 43
f)
Putting y = 54 in y = 4x + 4
54 = 4x + 4
Subtract 4 from both sides:
50 = 4x
Divide both sides by 4
x = 50/4
The value of x is not a whole number. Thus it is not possible that a figure has with 54 yellow tiles.

The various depreciation methods include:
Straight-line methodUnit-of-activity methodDouble-declining-balance methodSum-of-the-years-digit methodModified accelerated recovery systems (MACRS).The cost of the delivery truck on January 1, 2022 = $26,000

64 - (-2)⁵ ÷ 2³ + (-1)³ · (0.5)²
To solve this expression, we need to use the rules of order of operations, which dictate the order in which mathematical operations should be performed. The order of operations is typically abbreviated using the acronym PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
Using the order of operations, we can solve the expression as follows:
64 - (-2)⁵ ÷ 2³ + (-1)³ · (0.5)²
= 64 - (-2)⁵ ÷ 8 + (-1)³ · 0.25
= 64 - (-32) ÷ 8 + (-1)³ · 0.25
= 64 + 32 + (-1)³ · 0.25
= 96 + (-1)³ · 0.25
= 96 + (-1) · 0.25
= 96 - 0.25
= 95.75
Therefore, the final result of the expression is 95.75

[tex]n=45 \implies \frac{180(n-2)}{n}=\boxed{172^{\circ}}[/tex]
The degree measure of one angle of a 45-sided regular polygon is 172°.
What is an angle measure?When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.
Here, the polygon has 45 sides.
To find the measure of an interior angle of a regular polygon,
we make use of the formula for each angle = (n - 2) × 180 / n.
The formula calculated is only valid in cases of regular-sided polygons.
n = 45 substituting the value of n to the formula.
(n - 2) × 180 / n
= 180 ( 45-2) / 45
= 180 x 43 / 45
= 7740 / 45
= 172°
Therefore, the measure of one angle is 172°.

What is a polynomial?A polynomial is an algebraic expression.
A polynomial of degree n in variable x can be written as,
a₀xⁿ + a₁xⁿ⁻¹ + a₂xⁿ⁻² +...+ aₙ.
Given, We have to construct a polynomial of degree 5, a positive lead
co-efficient and zeros or roots are -5, -2, 0, 3, 6.
If roots are -5, -2, 0, 3, 6 factors are (x + 5), (x + 2), (x + 0), (x - 3), (x - 6).
∴The required polynomial is (x + 5)(x + 2)(x + 0)(x - 3)(x - 6).
= x(x + 5)(x + 2)(x - 3)(x - 6).
= (x² + 5x)(x² - 3x + 2x - 6)(x - 6).
= (x² + 5x)(x² - x - 6)(x - 6).
= (x² + 5x)(x³ - 6x² - x² + 6x -6x + 36).
= (x² + 5x)(x³ - 7x²+ 36).
= x⁵ - 7x⁴ + 36x² + 5x⁴ - 35x³ + 180x.
= x⁵ - 2x⁴ - 35x³ + 36x² + 180x.
