0 Expand 3(2x - 3y - 2)
The expanded form of 3(2x -3y -2) is given by the equation 6x -9y -6
The equation given is a linear equation in two variables and to simplify the equation 3(2x -3y -2), we need to use algebraic properties
The algebraic property used here is distributive property which says that a (b+ c) = ab + ac.
So, let us expand the equation using the algebraic property mentioned above
As a= 3, b=2x and c=3y+2
3(2x -3y -2)
3 (2x) -3(3y+2)
Using the property again with a=3, b=3y and c=2
3 (2x) -3(3y+2)
6x -3(3y) -3(2)
6x - 9y -6
Hence, the expanded form of 3(2x -3y -2) is given by the equation 6x -9y -6

Step-by-step explanation:
on the first birthday, we light one candle; on the second birthday 2 candles; and on the 120th birthday 120 candles. how many candles do we light total in all 120 birthdays? use the proper summation formula we learned in class.
Candles we light total in all 120 birthdays is 7260.
Arithmetic Progression is defined as the sequence of numbers where the difference is constant .
According to the given question
No of candle on 1st birthday = 1
no of candle on 2nd birthday =2
.
.
No of candle on 120th birthday= 120
The given situation can be represented in the form of sequence .
1,2,3,4,5,...,120.
The above sequence forms an Arithmetic Progression as the common difference is same that is 1.
To find the total candles we need to find the sum of the above AP.
Sum of AP [tex]=\frac{n}{2}[2a+(n-1)d][/tex] ...where a=first term , n=total number of terms , d=common difference .
a=1 , d=1 , n=120
Substituting the value we get
[tex]=\frac{120}{2} [2(1)+(120-1)1]\\ \\ =60[2+119] \\ \\ =60*121\\ \\ =7260[/tex]
Therefore , Total of 7260 candles will be light in all 120 birthdays.

The difference between two numbers is 12. The first number is 5 less than twice the second number. What are the two numbers?
Two expressions with an equal sign is called as Equation. If the difference between two numbers is 12. The first number is 5 less than twice the second number then the two numbers are 29 and 17.
What is Equation?Two expressions with an equal sign is called as Equation.
Let the two numbers be a and b.
Given equation is a-b=12 .....(1) and
The first number is 5 less than twice the second number i.e a=2b-5
Substitute a in (1)
2b-5-b=12
b-5=12
b=17
b=17 is the second number.
Now we have to find first number so
a=2b-5...(2)
Substitute b=17 in (2)

2. (g)(-1)
3. (h)(4)
6. (f - g)(-3)
7. (g + h)(-2)
4. (f + g)(-2)
Answer:
see explanation
Step-by-step explanation:
1
f(4) means what is the value of f(x) when x = 4
substitute x = 4 into f(x)
f(4) = 2(4) - 5 = 8 - 5= 3
-----------------------------------
2
substitute x = - 1 into g(x)
g(- 1) = 3(- 1)² + 5 = 3(1) + 5 = 3 + 5 = 8
--------------------------------------
3
substitute x = 4 into h(x)
h(4) = 3(4) + 2 = 12 + 2 = 14
--------------------------------------
4
(f + g)(- 2)
= f(- 2) + g(- 2)
= 2(- 2) - 5 + 3(- 2)² + 5
= - 4 - 5 + 3(4) + 5
= - 9 + 12 + 5
= - 9 + 17
= 8
-----------------------------------------
5
(f + h)(2)
= f(2) + h(2)
= 2(2) - 5 + 3(2) + 2
= 4 - 5 + 6 + 2
= - 1 + 8
= 7
-------------------------------------------------
6
(f - g)(- 3)
= f(- 3) - g(- 3)
= 2(- 3) - 5 - (3(- 3)² + 5)
= - 6 - 5 - ( 3(9) + 5)
= - 11 - ( 27 + 5)
= - 11 - ( 32)
= - 11 - 32
= - 43
------------------------------------------------
7
(g + h)(- 2)
= g(- 2) + h(- 2)
= 3(- 2)² + 5 + 3(- 2) + 2
= 3(4) + 5 - 6 + 2
= 12 + 5 - 4

Thus, the relationship between the students and the tickets sold is not a function A function is a relation in which one input can have only one output.
Let the students be = x
Let the number of tickets sold by the student be = y
Thus, from the table, it can be inferred -
Student 1 and student 3 are having the same number of outputs meaning that the number of tickets sold by student 1 and student 3 is the same.

Evaluate each logarithm.
log₄₉7
The answer to the given logarithm expression is log₄₉7 = 1/2
Another technique to clarify exponents in mathematics is through logarithms. A base number's logarithm equals another number.
For instance, log10 100 = 2 if 102 = 100. A logarithm is defined as an influence by which variety must be raised to receive another value. this is often the foremost convenient thanks to represent large numbers. Logarithms have several important properties that prove that logarithmic multiplication and division is written because the logarithm of addition and subtraction. The log is named the logarithm of base e. The logarithm is represented by ln or loge. where 'e' represents Euler's constant, approximately capable 2.71828. as an example, the log of 76 is written as ln 76. The log defines what percentage times 'e' must be multiplied to induce the required output.
We need to evaluate log₄₉7
Using Property
logₙ (a) = 1 / logₐ (n)
log₄₉7 = 1/ log₇ 49
Using the properties of log again logₐ (mⁿ) = n logₐ m
49 = 7²log₇ 49
can be written as
log₇ 49 = 2 log₇ 7
We know that logₐ a = 12 log₇ 7= 2

Find the inverse of each function. Is the inverse a function?
y=(1-2 x)²+5
The inverse function returns the original value for which the output of a function was given.
[tex]y^{-1}[/tex] = -1 ± √(x - 5) /2 be the inverse the function y = (1 - 2x)² + 5.
What is the inverse formula?The inverse function returns the original value for which the output of a function was given. When it comes to functions, f and g are inverse, with f(g(x)) = g(f(x)) = x. A function that is made up of its inverse returns the original value. The inverse of f is then g(y) = (y - 5)/2 = x.
An inverse in mathematics is a function that serves to "undo" another function. That is, if f(x) produces y, then putting y into the inverse of f yields x. Invertible functions are those that have an inverse, which is denoted by f1.
Let the equation be y = (1 - 2x)² + 5
simplifying the above equation, we get
√(x - 5) y = (1 - 2x)² + 5
x = (1 - 2y)² + 5
The function of x be x = (1 - 2y)² + 5
x - 5 = (1 - 2x)²
± √(x - 5) = (1 - 2y)
± √(x - 5) - 1 = 2y
Divide both sides of the equation by 2, we get
[± √(x - 5) - 1]/2 = 2y/2
[± √(x - 5) -1] /2 = y
[tex]y^{-1}[/tex] = -1 ± √(x - 5) /2
Therefore, the inverse of the function be [tex]y^{-1}[/tex] = -1 ± √(x - 5) /2.
