Answer:
y = (x+8)(x+3)
Step-by-step explanation:
If you multiply
(x+8)(x+3),
you get x^2 + 3x + 8x + 24
This simplifies to x^2 + 11x + 24, same as the original question.
The graph of y=x² + 11x + 24 is equivalent to the y=(x+8)(x+3).
What is Polynomial?An algebraic expression known as a polynomial requires that all of its exponents be whole numbers. Any polynomial must have variable exponents that are non-negative integers. Constants and variables are components of a polynomial.
We have Graph whose equation is
y=x² + 11x + 24
Now, factories the above equation using splitting the middle term
y=x² + 11x + 24
y=x² + 8x + 3x + 24
y = x(x+8) + 3(x+8)
y= (x+3)(x+8)
Thus, the factors are (x + 3)(x+8).

Which of the following is a point on the plane curve defined by the parametric equations?
x=3t
y=18t^2+12t+2
The ANSWER is (-1,0) ---- PLEASE EXPLAIN!!! THANK YOU x1000000!!!
By eliminating the parameter t and evaluating the function at x = -1 we conclude that the parametric equations contains the point (x, y) = (-1, 0).
How to determine that point belongs to a set of parametric functions
In this case we must determine if a point in rectangular format belongs to a set formed by two parametric functions. The functions are parametric as they are based in a parameter t. A quick approach consist in reduce the number of equations by eliminating the parameter.
The first equation is represented below:
t = x/3
And the parameter is substituted in the second equation:
y = 18 · (x/3)² + 12 · (x/3) + 2
y = 2 · x² + 4 · x + 2
If we know that x = -1, then the y-value is:
y = 2 · (- 1)² + 4 · (- 1) + 2
y = 0
By eliminating the parameter t and evaluating the function at x = -1 we conclude that the parametric equations contains the point (x, y) = (-1, 0).

Put the following equation of a line into slope-intercept form, simplifying all fractions. 5x+6y=42
Answer:
[tex]y=-\frac{5}{6} + 7[/tex]
Step-by-step explanation:
Slope-intercept formula requires us to isolate the y variable. We can do this in just a couple of steps.
1) Move 5x from the left to the right side by subtracting 5x from both sides. This cancels out the 5x on the left side, and remember, what we do to one side we must do to the other to keep the equation balanced.
[tex]6y=-5x+42[/tex]
2) Divide both sides by 6. Again, we are cancelling out the 6 on the left but we must also divide on the right. This would mean dividing -5 and 42 by 6 to get:
[tex]y=-\frac{5}{6} + 7[/tex]

What is the Arithmetic Sequence?Arithmetic sequence is a sequence where each consequtive term has a common constant difference.
An arithmetic sequence, therefore, is defined by two parameters, viz. the starting term and the common difference.
The arithmetic sequence formula is;
aₙ = a + (n − 1)d,
where;
a is the first term
n is the position of the term in the sequence
d is the common difference
aₙ is the nth term of the sequence.
Our sequence is 10, 14, 18, 22 up to row 20.
Using the sequence formula;
[tex]a_{20} = 10 + (20 - 1)4.\\a_{20} = 10 + (19\times 4)\\a_{20}= 10 + 76\\a_{20}= 86.[/tex]

Part C: After approximately how many years is the number of homes in Neighborhood A and Neighborhood B the same? Justify your answer mathematically. (4 points)

Answer:
We know that:
Neighbourhood A = 30 homes and the number increases by 20% each year
Neighbourhood B = 45 homes, and each year 3 new homes are built.
A.
Neighbourhood A and B are as follows:
For neighbourhood A: f(x) =
For neighbourhood B: f(x) = 45 + 3x

Over five years:
Neighbourhood A has =
Neighbourhood A =
Neighbourhood A = 74.65 homes
Neighbourhood B: = 45 + 3(5)
Neighbourhood B: = 45 + 15
Neighbourhood B: = 60 homes
C.
To determine how many years the number of homes are the same for neighbourhood A and B, we need to equate both together.
So x= 3.3

14.35: a baseball league has nine teams. during the season, each of the nine teams plays exactly three games with each of the other teams. what is the total number of games played?
Answer:
One team must play 8 games 3 times equals 24 games
One team must play 24 games
But each game uses 2 teams so there are 12 games in all
Or 9 * 24 / 2 = 108 games
Check: If there were 3 teams then one team must play
2 games 3 times for a total of 6 times so the total of games played will be six for each team or 18 games, but each game uses 2 teams so the total of games is nine: 1-2, 2-3, 1-3 (each team has played its opponent once) - 3 * 3 = 9

Tammy said the product of 5/7 and 1 1/4 is 1 3/4.
Answer:
Tammy is incorrect
Step-by-step explanation:
The product of 5/7 and 1 1/4 is,
(5/7) x (1 1/4)
turn the mixed number to a whole number.
1 1/4= 4/4 + 1/4 = 5/4
(5/7) x (5/4) = 25/28 which is approximately 0.8929
Tammy believes it equals 1 3/4
1 3/4 = 4/4 + 3/4 = 7/4 which is 1.75

John and Elijah are both driving from New York City to Richmond.
John leaves at 7:20 and averages 60 mph (miles per hour) on the way.
Elijah leaves at 7:30 and averages 62 mph on the way.

y = 60x + 10 ...1
y = 62x ...2
The time is taken by Elijah to cross John will be
62x = 60x + 10
