Prove: An even plus an odd
equals an odd.
(2m) + (2n + 1) = 2(m + [?] + [ ]
odd
Answer:
2(m + [n)] + [1]
Step-by-step explanation:
(2m) + (2n + 1) =
= 2m + 2n + 1
= 2(m + n) + 1
= 2(m + [n)] + [1]
The simplification of the expression would be equal to 2(m + [n)] + [1].
What is a simplification of an expression?Usually, simplification involves proceeding with the pending operations in the expression.
Like, 5 + 2 is an expression whose simplified form can be obtained by doing the pending addition, which results in 7 as its simplified form.
Simplification usually involves making the expression simple and easy to use later.
An even plus an odd equals an odd.

4. Two consecutive even numbers are such that the sum of the larger number and three times the smaller number is 42. Find the two numbers.
Answer: The two numbers are 10 and 12.
Step-by-step explanation:
Let the two consecutive numbers are x and x +2.
As per given, we have
[tex](x+2)+3x=42\\\\\Rightarrow\ 4x+2=42\\\\\Rightarrow\ 4x=40\\\\\Rightarrow\ x=10[/tex]
Smaller number = 10
Larger number = 10+2=12
Therefore, The two numbers are 10 and 12.
Write a quadratic function that has been translated 1
units to the right and 3 units down.
Step-by-step explanation:
Hi,
f(x) = (x - 1) - 3
The -1 is the 1 unit to the right (even though it's being subtracted, it's going to the right because it's embedded with the x)
And the -3 is not embedded with the x, meaning the function will move 3 units down.

Jacob has a list of the estimated costs for each semester to attend a four-year university. What is the total estimated cost to attend college for four years?
Tabel:
Item Cost
Tuition and Fees $3,725.00
Room and Board $2,800.00
Books and Supplies $700.00
Personal Expenses $900.00
A. $8,125
B. $16,250
C. $65,000
D. $32,500
Answer: A, 8125
Step-by-step explanation:
3,725 + 2800 + 700 + 900
3725 + 2800 = 6525
700 + 900 = 1600
6525 + 1600 = 8125
The total estimated cost to attend college for four years is $65,000.00.
Option C is the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Number of semesters in 4 years.
= 2 x 4
= 8
Now,
To find the total cost to attend college for four years, we need to multiply the cost of each item by the number of semesters in four years and add them all together.
So,
Tuition fees:
8 semesters x $3,725.00/semester
= $29,800.00
Room and board:
8 semesters x $2,800.00/semester = $22,400.00
Books and supplies:
8 semesters x $700.00/semester = $5,600.00
Personal expenses:
8 semesters x $900.00/semester = $7,200.00
Therefore,
The total estimated cost to attend college for four years.
= $29,800.00 + $22,400.00 + $5,600.00 + $7,200.00
= $65,000.00
Thus,
The total estimated cost to attend college for four years is $65,000.00.

Camila is working two summer jobs, making $10 per hour lifeguarding and $6 per hour walking dogs. Last week Camila worked 5 more hours lifeguarding than hours walking dogs and earned a total of $114. Write a system of equations that could be used to determine the number of hours Camila worked lifeguarding last week and the number of hours she worked walking dogs last week. Define the variables that you use to write the system.
Let L = the numbers of hours lifeguarding
Let D = the number of hours walking dogs
Camila makes $10 per hour lifeguarding, so in L hours she will make 10L dollars. Camila makes $6 per hour walking dogs, so in D hours she will make 6D dollars. The total amount earned 10L+6D equals $114.
Since Camila worked 5 more hours lifeguarding than hours walking dogs, she worked more hours lifeguarding, so if we add 5 to the number of hours walking dogs, we will get the number of hours lifeguarding, meaning L equals D+5.
10L+6D=114
L=D+5

The second one works becuase the domain aren’t repeated and the range being repeated (or known as y) is but that deosn’t matter.
Answer:
B
Step-by-step explanation:
Hello There!
In order for the relations to be a function the x values may not repeat
For answer choice A the x value -2 repeats multiply times therefore the relation is not a function
For answer choice B each x value has a different y value so this might be our answer but just to be safe lets look at the other answer choices
For answer choice C the x values -3 and 2 repeat therefore it is not a function
For answer choice D the x value 2 repeats therefore the relation is not a function
So we can conclude that the correct answer is B

Answer: The answer to what is the measure of angle x is 48°.
Step-by-step explanation: It’s because this angle is complementary Two Angles are Complementary when they add up to 90 degrees (a Right Angle). They don't have to be next to each other, just so long as the total is 90 degrees. Example: 5° and 85° are complementary angles.
48°+42°=90° and this is a right scalene triangle.
