Answer:
-1/2
Step-by-step explanation:
3(y + 12) = 24
3y + 36 = 24
3y = 24 - 36
3y = -12
y = -12/3
y = -4
Value of 1/8 × y
1/8 × (-4)
-4/8
-1/2
Answer:
-1/2
Step-by-step explanation:
3(y + 12) = 24
~Simplify left side
3y + 36 = 24
~Subtract 36 to both sides
3y = -12
~Divide 3 to both sides
y = -4
~Now substitute in 1/8y
1/8(-4)
= -1/2

James walked at a constant rate for 3 hours as shown in the graph. Jaycee walked 14.5 miles in 3 hours at a constant rate. Who walked farther, and how much farther?
Answer:
Jaycee walked [tex]2.5[/tex] miles farther.
Step-by-step explanation:
Given
Jaycee walked 14.5 miles in 3 hours at a constant rate.
Step 1 of 1
From given graph [tex]$(1,4)$[/tex], [tex]$(2,8)$[/tex] is a two points.
Then the equation of the line are [tex]$y=4 x$[/tex]
This imply at [tex]$x=3[/tex] ;

im confused on the bottom circle answer its a bit weird it reads "a. (use algebra) Use the diagram at the right. What algebraic expression represents GK?
b. if GK = 30, what are GH and JK?"
Step-by-step explanation:
well you need to add the right expressions for the shorter lines so that there is no overlap. otherwise GK would be too long.
so, how can we combine the 3 red lines to get exactly GK ?
we cannot just add 2 of these lines. the results would always be either too long or too short.
but we see "2x + 3" overlaps a bit with "4x - 3". and hey, the third line "x" is just the length of the overlap of the other 2 lines.
so, we can add the first 2 lines, IF we reduce first one of them by the overlap length.
I picked the second line.
so, we have
2x + 3 - x + 4x - 3 = GK
5x = GK
so, "5x" is the algebraic expression representing GK.
now, if GK = 30, then we know
5x = 30
x = 6
GH = 2x + 3 - x (again, we need to shorten that line by the overlap length to count only to H)
= 2×6 + 3 - 6 = 6 + 3 = 9
JK = GK - GJ = 30 - (2x + 3) (here we need the full line, as we are dealing with J)
= 30 - 2×6 - 3 = 15

A set of integers each is greater than 40 and less than 46. List the members.
Answer:
{41 , 42 , 43 , 44 , 45}
Answer:
Set (x) = {41, 42, 43, 44, 45}
Step-by-step explanation:
Given statement,
→ A set of integers each is greater than 40 and less than 46.
Now the set will be,
→ 40 < x < 46
Then the members of the set are,
→ 40 < x < 46
→ 40 < 41 < 46
→ 40 < 42 < 46
→ 40 < 43 < 46
→ 40 < 44 < 46
→ 40 < 45 < 46
The list of required integers are,
→ 41, 42, 43, 44, 45
→ {41, 42, 43, 44, 45}
Hence, this is the correct answer.

Last year’s match at Wimbledon between John Isner and Nicolas Mahut, which lasted 11 hours and 5 minutes, set a record for the longest match in tennis history. The fifth set of the match lasted 8 hours and 11 minutes. Approximately what fraction of the whole match was taken up by the fifth set?
Using proportions, it is found that approximately 74% of the whole match was taken up by the fifth set.
What is a proportion?A proportion is a fraction of total amount, and is given by the number of desired outcomes divided by the number of total outcomes.In this problem:
To build the fraction, we find the times in minutes.The fifth set took 8 hours and 11 minutes, that is, 8 x 60 + 11 = 491 minutes.In total, the match lasted 11 hours and 5 minutes, that is, 11 x 60 + 6 = 665 minutes.Hence:
[tex]p = \frac{491}{665} \approx 0.74[/tex]

What is the value of the 20th term in this sequence? f(n)=6n−18
The value of the 20th term in this sequence will be 102
Since we are given f(n)=6n−18.
In this case, we have been given n to be 20. Therefore, f(n)=6n−18 will then be written as:
f(n)=6n−18
f(20) = 6(20) - 18
f(20) = 120 - 18
f(20) = 102
In conclusion, value of the 20th term in this sequence will be 102

A rectangle has sides measuring (4x + 5) units and (3x + 10) units.
Part A: What is the expression that represents the area of the rectangle? Show your work. (4 points)
Part B: What are the degree and classification of the expression obtained in Part A? (3 points)
Part C: How does Part A demonstrate the closure property for polynomials? (3 points)
Part A
Like with any other rectangle, we multiply the length and width to get the area
This applies even when we have algebraic expressions like this (recall that x is simply a placeholder for a number).
So,
area = length*width
area = (4x+5)*(3x+10)
area = w(3x+10) ..... replace (4x+5) with the variable w
area = 3xw + 10w ..... distribute
area = 3x(4x+5)+10(4x+5) .... plug in w = 4x+5
area = 3x*4x+3x*5 + 10*4x+10*5 .... distribute again
area = 12x^2+15x + 40x+50
area = 12x^2+55x+50
Answer: 12x^2+55x+50
=======================================================
Part B
The degree of any single variable polynomial is the largest exponent. In this case, the largest exponent is 2. This 2nd degree polynomial is considered a quadratic. Because we have three terms, this quadratic polynomial is also a trinomial. So there are many ways to describe the result of part A. Possibly the quickest way to describe it is to say "quadratic trinomial" to say all that has been mentioned in this paragraph.
Answers:
Degree = 2Classification = quadratic trinomial=======================================================
Part C
The concept of closure is the idea of taking two objects of the same type, applying some operation to them, and getting an output object of the same type.
Admittedly that last paragraph is a bit vague so I'll go over a few examples.
If we take any two integers and add them up, then we get another integer. This shows integers are closed under addition.We can also multiply any two whole numbers to get some other whole number. This is another example of closure.A non-example would be dividing whole numbers. Something like 10/2 = 5 is a whole number but 10/3 = 3.33 is not. This shows that integers are not closed under division. We don't always get a whole number output.
With polynomials, multiplying any two of them will result in some other polynomial. It's basically using the two examples in the bullet points and building upon them. That's the short version of why polynomials are closed under multiplication.
For this particular problem, (4x+5), (3x+10), and 12x^2+55x+50 are all polynomials.
-----------
In terms of notation,
polynomialA * polynomialB = polynomialC
This notation hopefully shows that multiplying any two polynomials leads to another polynomial.
