The length of ribbon is 48 yards.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Kala got a prepaid debit card with $15.

Price of Ribbon = 24 cents per yard.

After purchase money left $3.48.

So, Price of Ribbon purchased = 15 - 3.48 = $11.52 = 1152 cents

length of ribbon = 1152/ 24

                           = 48 yards

To factor the expression 4x^2 - 25, we can use the difference of squares formula, which states that a^2 - b^2 can be factored as (a + b)(a - b).

In this case, we have 4x^2 - 25, which can be written as (2x)^2 - 5^2. Comparing it with the difference of squares formula, we can identify that a = 2x and b = 5. Therefore, the correct option is:

b. (2x)^2 - (5)^2

Using the difference of squares formula, we can factor it as follows:

(2x + 5)(2x - 5)

Hence, the correct factorization of 4x^2 - 25 is (2x + 5)(2x - 5), which is equivalent to option b.

Answer:

1/10 pound

Step-by-step explanation:

If you set up the equation as 3/5 - 1/2, you'll have to give them a common denominator. Multiply 3/5 by 2 and multiply 1/2 by 5, and now you can rewrite this equation as 6/10 - 5/10. From here, just subtract and you'll get 1/10.

The inverse of matrix A, if it exists, is:

A^(-1) = [7/43, 2/43; 10/43, 9/43]

To find the inverse of a matrix A, we need to determine if the matrix is invertible by calculating its determinant. If the determinant is non-zero, then the matrix has an inverse.

Given the matrix A = [9, -2; -10, 7], we can calculate its determinant as follows:

det(A) = (9 * 7) - (-2 * -10)

= 63 - 20

= 43

Since the determinant is non-zero (43 ≠ 0), we can proceed to find the inverse of matrix A.

The formula to calculate the inverse of a 2x2 matrix is:

A^(-1) = (1/det(A)) * [d, -b; -c, a]

Plugging in the values from matrix A and the determinant, we have:

A^(-1) = (1/43) * [7, 2; 10, 9]

Simplifying further, we get:

A^(-1) = [7/43, 2/43; 10/43, 9/43].

Multiplying so both equations have the same leading coefficient

In this case the coefficient of x of the first

x + 3y = -7

is 1

and for the second

-x + 2y = -8​

the coefficient is -1

We multiply the second by -1 both sides, so the coefficient is +1

-x + 2y = -8​

-1 (-x + 2y ) = -1( -8​)

x -2y = 8

Now we have

x + 3y = -7

x -2y = 8

Subtracting the second equation from the first

x + 3y = -7

x -2y = 8

Answer:

\(f(x)=\dfrac{-50(x-1)(x-2)}{(x-5)(x+5)}\)

Step-by-step explanation:

Since f(x) has asymptotes at x = 5 and x = -5, then the denominator of the rational function contains the terms (x - 5) and (x + 5):

\(f(x)=\dfrac{?}{(x-5)(x+5)}\)

Since f(x) has x-intercepts at x = 2 and x = 1, then the numerator of the rational function contains the terms (x - 2) and (x - 1):

\(f(x)=\dfrac{A(x-1)(x-2)}{(x-5)(x+5)}\)

Now substitute the point (0, 4) and solve for A:

\(f(0)=4\\\\\implies \dfrac{A(0-1)(0-2)}{(0-5)(0+5)}=4\\\\\\\implies -\dfrac{2}{25}A=4\\\\\\\implies A=-50\)

The value of the given expression −(8 − 12) + 60 + (−4)² will be 80.

Arithmetic operators are operators in mathematics where basic four operators involve. Addition, multiplication, division, and subtraction.

Addition =  addition of two or more numbers or variable

For example =3 + 4

Subtraction = Minus of any two or more numbers with each other called subtraction.

For example =8 - 9

Division = divide any two numbers or variable called division.

For example 7/3

Multiplication = to multiply any two or more numbers or variables called multiplication.

For example 5 × 4.

Given,

⇒  −(8 − 12) + 60 + (−4)²

⇒ -(-4) + 60 + 16

⇒ 4 + 60 + 16

⇒ 80

Hence "The value of the given expression −(8 − 12) + 60 + (−4)² will be 80".

To construct the difference table, we start by writing down the given sequence. Then, in the first column, we calculate the differences between consecutive terms. In the second column, we calculate the differences between the values in the first difference column. Similarly, in the third column, we calculate the differences between the values in the second difference column.

Analyzing the difference table, we observe that the third differences are constant at 3. This indicates a cubic pattern in the sequence, where the difference between consecutive terms is increasing by a constant amount each time.

To predict the next term, we take the last term of the sequence (266) and add the next difference (23) to it:

Next term = 266 + 23 = 289

Therefore, based on the pattern observed in the difference table, the next term in the sequence is predicted to be 289.

Lol, thank you for telling me this information..

Answer:

Let's call the number of diners at the Italian restaurant x, and the number of diners at the Mexican restaurant y. We can set up the following system of equations to represent the problem:

Italian restaurant: $20 + 2x = $30 + $1y

Mexican restaurant: $30 + $1y = $20 + 2x

Subtracting $20 from both sides of the first equation and $30 from both sides of the second equation, we get:

Italian restaurant: 2x = $10 + $1y

Mexican restaurant: $1y = $10 + 2x

Multiplying both sides of the first equation by 1/2, we get:

x = $5 + $0.5y

Substituting this expression for x in the second equation, we get:

$1y = $10 + 2($5 + $0.5y)

Expanding the expression on the right side, we get:

$1y = $10 + $10 + $1y

Subtracting $1y from both sides, we get:

0 = $10

This equation is true, so the system of equations is consistent.

Since the total donations from each restaurant would be the same, we can set the total donations equal to each other and solve for the number of diners at each restaurant. The total donation from the Italian restaurant is $20 + 2x, and the total donation from the Mexican restaurant is $30 + $1y. Setting these expressions equal to each other, we get:

$20 + 2x = $30 + $1y

Subtracting $20 from both sides and $1 from both sides, we get:

2x - 2 = $10 + $1y - $1

Combining like terms on both sides, we get:

2x - 2 = $10 + $1y - $1

2x - 2 = $9 + $1y

2x - $9 - $1y = 2 - $9

2x - $1y = -$7

Dividing both sides by 2, we get:

x - $0.5y = -$3.5

Substituting this expression for x in the first equation, we get:

$20 + 2(-$3.5) = $30 + $1y

Simplifying the expression on the left side, we get:

$20 - $7 = $30 + $1y

Subtracting $20 from both sides, we get:

-$7 = $10 + $1y

Subtracting $10 from both sides, we get:

-$17 = $1y

Dividing both sides by -1, we get:

$17 = -$1y

Multiplying both sides by -1, we get:

-$17 = $1y

Dividing both sides by $1, we get:

-$17/$1 = $1y/$1

Simplifying the expression on the left side, we get:

-17 = y

Thus, the number of diners at the Mexican restaurant is -17, and the number of diners at the Italian restaurant is x = $5 + $0.5y = $5 + $0.5(-17) = $5 - $8.5 = -$3.5.

The four points that appear on the line are:

B- (0,-9)

D-(9,-3)

E-(6,-5)

F-(3,-7)

Step-by-step explanation:

The equation of the line in slope-intercept form is:

y = mx + b

Being m the slope and b the y-intercept.

We are given the values of m=2/3 and b=-9, so the equation of the line is:

y = 2/3 x - 9

We must select from the list below the points that lie on the line. To test each point, we substitute the value of x and calculate the value of y. If it matches the given y-coordinate, then the point lies on the line.

Calculate: y = 2/3 (2) - 9 = -23/3.

This point is not on the line because -23/3 ≠ 3

Calculate: y = 2/3 (0) - 9 = -9.

This point is on the line because -9 = -9

Calculate: y = 2/3 (1) - 9 = -25/3.

This point is not on the line, because -25/3 ≠ 3

Calculate: y = 2/3 (9) - 9 = -3.

This point is on the line because -3 = -3

Calculate: y = 2/3 (6) - 9 = -5.

This point is on the line because -5 = -5

Calculate: y = 2/3 (3) - 9 = -7.

This point is on the line because -7 = -7

The four points that appear on the line are:

B- (0,-9)

D-(9,-3)

E-(6,-5)

F-(3,-7)
