Graph the linear equation y = 2x + 1.
What is the largest possible product of two positive integers whose sum is 9?
Answer:
The largest possible product of two positive integers whose sum is 9 is achieved when the two integers are as far apart as possible, which occurs when one integer is the largest possible integer and the other is the smallest possible integer. The largest possible integer is the one that is closest to but less than 9, which is 8, and the smallest possible integer is 1. The product of 8 and 1 is 8, so the largest possible product of two positive integers whose sum is 9 is 8.
39 is 0.3% of what number? Use pencil and paper. Would you expect the answer to be a lot less than 39, slightly less than 39, slightly greater than 39, or a lot greater than 39? Explain.
39 is 0.3% of 13,000.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
let the number be x
So, 0.3% of x= 39
0.3/ 100 x= 39
0.3 x = 3900
x= 3900/ 0.3
x= 13000

Answer:
(2,0)
Step-by-step explanation:
5x + 9y = 10
4x -3y = 8 If I multiple this second equation all the way through by 3, then the y's would cancel out when I add the equations together.
12x -9y = 24 multiplied the second equation through by 3
5x + 9y = 10 Add the 2 equations together
17x = 34 Divide both sides by 14
x = 2
Plug 2 in for x for either of the two original equations and solve for y
5x + 9y = 10
5(2) + 9y = 10
10 + 9y = 10 Subtract 10 from both sides
9y = 0 Divide both sides by 0
y = 0

Find the 200th term in the sequence below.
a₁ = 8
d=12
The 200th term in the sequence is 2,396.
To find the 200th term in the sequence we have the formula:
an=a1+(n-1)d --------(1)
Given that values of a1 and d are 8,12
"a1" is called the first value of the sequence.
"d" is called the difference between two numbers.
Assume that n is 200 because we have to find the 200th term.
Now, we will substitute all the values in the above equation(1)
an=a1+(n-1)d
a200=8+(200-1)12
a200=8+(199)12
a200=8+2,388
a200=2,398.

The correct option for the given linear equation condition is D. i.e. Liza will pass Ralph after 5 hours, and they each will have travelled 325 miles.
What is a linear equation?
When the parameter in the equation has a degree of 1, the system is said to be linear. One, two, or even more variables could be present.
The collection of two or more linear equations involving the same variables is known as a system of linear equations.
From the question,
The situation is given as:
y = 60x + 25
y = 65x
The time after Liza leaves, she passes Ralph will be
or, 65x = 60x + 25
or, 5x = 25
or, x = 5 hours
Then the distance covered by both of them, then after 5 hours will be
y = 65 (5)
y = 325 miles
Hence, the correct option is D.

Applying the Pythagorean theorem, the missing side of each of the right triangle are:
i. c = 15.8 m
ii. s = 24.1 cm
iii. a = 12.8 feet
iv. t = 4.6 inches
Pythagorean Theorem.Pythagorean theorem is one that can be used to determine the third unknown side of a right angled triangle. It is given by:
/Hyp/^2 = /Adj/^2 + /Opp/^2
The missing side of each of the right triangle can be determined as:
1. Let the value of unknown hypotenuse side by represented by c, so that:
/Hyp/^2 = /Adj/^2 + /Opp/^2
c^2 = /13/^2 + /9/^2
= 169 + 81
= 250
c = [tex]\sqrt{250}[/tex]
= 15.8
c = 15.8 m
2. Let the value of unknown hypotenuse side be represented by s, so that;
/Hyp/^2 = /Adj/^2 + /Opp/^2
s^2 = /16/^2 + /18/^2
= 256 + 324
= 580
s = [tex]\sqrt{580}[/tex]
= 24.1
s = 24.1 cm
3. Let the value of unknown adjacent side be represented by a,
/Hyp/^2 = /Adj/^2 + /Opp/^2

a = [tex]\sqrt{165}[/tex]
= 12.8
a = 12.8 ft
4. Let the unknown adjacent side be represented by a,
/Hyp/^2 = /Adj/^2 + /Opp/^2
/11/^2 = t^2 + /10/^2
121 = t^2 + 100

with full explanations and working please
The matrix equations are solved as

b) The value of matrix X is [tex]X=\begin{pmatrix}-5&1\end{pmatrix}[/tex]
What is multiplication of matrices?
The product of two matrices A and B is defined if the number of columns of A is equal to the number of rows of B. The first matrix must have the same number of columns as the second matrix has rows. The number of rows of the resulting matrix equals the number of rows of the first matrix, and the number of columns of the resulting matrix equals the number of columns of the second matrix
Given data ,
a)
Let the value of the matrix be X
Now , the equation is
[tex]2X = \begin{pmatrix}-4&0&8\end{pmatrix}[/tex]
Now , on simplifying the equation , we get
Divide by 2 on both sides of the equation , we get
[tex]X = \begin{pmatrix}-4&0&8\end{pmatrix} / 2[/tex]
Now , the value of matrix X is
[tex]X = \begin{pmatrix}-2&0&4\end{pmatrix}[/tex]
Therefore , the value of matrix X is [tex]X = \begin{pmatrix}-2&0&4\end{pmatrix}[/tex]
b)
Let the value of the matrix be X
Now , the equation is
[tex]3X\:-\:\begin{pmatrix}1&7\end{pmatrix}=\begin{pmatrix}-16&-4\end{pmatrix}[/tex]
On simplifying the equation , we get
Adding [tex]\begin{pmatrix}1&7\end{pmatrix}[/tex] on both sides of the equation , we get
[tex]3X=\begin{pmatrix}-16&-4\end{pmatrix}+\begin{pmatrix}1&7\end{pmatrix}[/tex]
Now , the value for 3X can be calculated as adding the 2 matrices
[tex]3X=\begin{pmatrix}-15&3\end{pmatrix}[/tex]
Divide by 3 on both sides of the equation , we get
[tex]X=\frac{1}{3}\begin{pmatrix}-15&3\end{pmatrix}[/tex]
So , [tex]X=\begin{pmatrix}-5&1\end{pmatrix}[/tex]
Therefore , the value of matrix X is [tex]X=\begin{pmatrix}-5&1\end{pmatrix}[/tex]
Hence , the matrix equations are solved as
a) The value of matrix X is [tex]X = \begin{pmatrix}-2&0&4\end{pmatrix}[/tex]
b) The value of matrix X is [tex]X=\begin{pmatrix}-5&1\end{pmatrix}[/tex]

ƒ”(x)=6x, f'(-3)=20, ƒ(-3)=-5
f(x)=?
Answer:
f(x) = x^3 - 7x + 1
Step-by-step explanation:
ƒ”(x)=6x ==> ƒ”(x)=6 * (x^1)
f'(x)=6/(1+1) * x^(1+1) + C ==> C is a constant that doesn't affect the derivative
f'(x)=6/2 * x^2 + C ==> simplify the first derivative
f'(x)=3 * x^2 + C ==> f'(x)=3(x^2) + C
f'(-3)=3((-3)^2) + C ==> plug in -3 into the derivative equation
f'(-3)=3(9) + C ==> simplify
20=3(9) + C ==> plug in 20 for f'(-3)
20=27+C
20-27=27-27+C ==> solve for C
C=-7
f'(x)=3(x^2) + (-7) ==> plug in -7 for C
f'(x)=3(x^2) - 7 ==> simplify
f(x) = 3/(2+1) * x^(2+1) - 7x + C
f(x) = 3/3 * x^3 - 7x + C
f(x) = x^3 - 7x + C
f(-3) = (-3)^3 - 7(-3) + C ==> plug in -3 into f(x)
f(-3) = -27 - (-21) + C
f(-3) = -27 + 21 + C ==> simplify
f(-3) = -6 + C
-5 = -6 + C ==> plug in -5 for f(-3)
-5 + 6 = -6 + 6 + C ==> solve for C
C = 1 ==> simplify

Ashley's hair grew 1 and 1/2 inches in 2 and 3/4 of a month. At what
Rate did ashley's hair grow per month?
Ashley's hair grew at a rate of approximately 0.545 inches per month.
What is the rate of change?
Rate of change problems can generally be approached using the formula R = D/T, or rate of change equals the distance traveled divided by the time it takes to do so.
To find the rate at which Ashley's hair grew per month, we need to divide the total amount of hair growth by the number of months.
First, let's convert the units to a common denominator. 1 and 1/2 inches is the same as 3/2 inches, and 2 and 3/4 months is the same as 11/4 months.
Now we can divide the total amount of hair growth (3/2 inches) by the number of months (11/4 months) to get the rate at which Ashley's hair grew per month:
(3/2 inches) / (11/4 months) = (3/2) * (4/11) inches/month
= 6/11 inches/month
= approximately 0.545 inches/month
Therefore, Ashley's hair grew at a rate of approximately 0.545 inches per month.

20. A pair of standard dice are rolled. What is

given that the sum of the numbers on the
dice is at least 8?
The probability that at least one die is a 5, given that the sum of the numbers on the dice is at least 8 = 2/5
What is probability?
Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.
The outcomes when the sum dice is 8 are
S = { (2,6), (3,5), (4,4), (5,3) , (6,2)}
Total outcomes = 5
Number of outcomes when there is at least one die is a 5,
given that the sum of the numbers on the dice is at least 8 = 2
Probability = (Number of possible outcomes)/(Total number of outcomes)

So , the total possible outcomes are 6 because are only 6 highest outcome possible
The factors of 4 are the numbers 1 , 2 and 4 which means its 3 outcomes
And the multiple of 3 are the numbers 3 and 6 which means it has 2 outcome
