Step-by-step explanation:

f(n+1) = f(n) -2

We know f(1) = 10

Let n=1

f(1+1) = f(1) -2

f(2) = 10-2 =8

We now know f(2)

Let n=2

f(2+1) = f(2)-2

f(3) = 8 -2=6

f(3) =6

Answer:

Terry has 20 quarters and 18 dimes

Step-by-step explanation:

Let

x -----> the number of quarters

y ----> the number of dimes

Remember that

1 quarter=$0.25

1 dime=$0.10

we know that

x=y+2 ----> equation A

0.25x+0.10y=6.80 -----> equation B

Substitute equation A in equation B and solve for y

0.25(y+2)+0.10y=6.80

0.25y+0.50+0.10y=6.80

0.25y+0.10y=6.80-0.50

0.35y=6.30

y=18 dimes

Find the value of x

x=y+2 -----> x=18+2=20 quarters

therefore

Terry has 20 quarters and 18 dimes

To determine the number of quarters and dimes Terry has, set up two equations based on the information provided, solve one of the equations for one variable, and substitute this into the second equation. Solve the equation to get the number of dimes and substitute it into the first equation to get the number of quarters.

To solve this, we can use algebra, setting up equations to represent the problem and then solve it.

Let F represent the number of dimes (since a dime is worth $0.10) and let Q represent the number of quarters (since a quarter is worth $0.25). We have two key pieces of information:

From the first equation, we can substitute F + 2 for Q in the second equation: 0.10F + 0.25(F + 2) = 6.80.

Solve this equation to find the value of F, representing the number of dimes, Terry has. Then, substitute the value of F into the first equation to determine the number of quarters Terry has.

The domain but not the range of the transformed function is the same as that of the parent function ⇒ answer D

Step-by-step explanation:

* Lets talk about the transformation

- If the function f(x) reflected across the x-axis, then the new

 function g(x) = - f(x)

- If the function f(x) translated horizontally to the right  by h units,

 then the new function g(x) = f(x - h)

- The domain of a function is set of the values of x which make

  the function defined

- The range is the set values of y that corresponding with the domain

- The domain of the function f(x) = IxI is the set of all real numbers

∴ The domain of f(x) is {x : x ∈ R}

- The range of  the function f(x) = IxI is the set of all real numbers

  greater than or equal 0

∴ The range f(x) = {y : y ≥ 0}

∵ f(x) reflected across the x-axis, then it will be change to g(x) = -IxI

∴ All the y-coordinates of the point on the function will be change

  from positive values to negative values

∵ The rang of f(x) is {y : y ≥ 0}

∴ The range of g(x) is {y : y ≤ 0}

∵ After the reflection the function translated 6 units to the right

∴ The x will change to x - 6

∴ The function will be h(x) = -Ix - 6I

- There is no values of x make h(x) undefined, then its domain is

  set of all real number

∴ The domain of h(x) is {x : x ∈ R}

∵ The domain of f(x) is {x : x ∈ R}

∵ The range of h(x) is the same the range of g(x)

∴ The range of h(x) is {y : y ≤ 0}

- f(x) and h(x) have same domains and different ranges

∴ The correct statement is: The domain but not the range of the

   transformed function is the same as that of the parent function

Final answer:

To find four consecutive even integers with a sum of -52, we denote the smallest integer as x and use the equation x + (x+2) + (x+4) + (x+6) = -52 to find that these integers are -16, -14, -12, and -10.

Explanation:

To find four consecutive even integers with a sum of -52, let's denote the smallest of these integers as x. Consequently, the next three integers can be represented as x+2, x+4, and x+6. The sum of these four integers can be expressed as the equation x + (x+2) + (x+4) + (x+6) = -52.

Combining like terms gives us 4x + 12 = -52. Subtracting 12 from both sides gives 4x = -64, and dividing both sides by 4 yields x = -16. Therefore, the four consecutive even integers are -16, -14, -12, and -10.

The four consecutive even integers with a sum of -52 are -16, -14, -12, and -10.

Let's denote the four consecutive even integers as [tex]\( x \), \( x+2 \), \( x+4 \), and \( x+6 \)[/tex].

According to the problem, their sum is -52. So, we can set up the equation:

[tex]\[ x + (x + 2) + (x + 4) + (x + 6) = -52 \][/tex]

Now, let's solve for \( x \):

[tex]\[ 4x + 12 = -52 \][/tex]

Subtract 12 from both sides:

[tex]\[ 4x = -52 - 12 \][/tex]

[tex]\[ 4x = -64 \][/tex]

Divide both sides by 4:

[tex]\[ x = \frac{-64}{4} \][/tex]

[tex]\[ x = -16 \][/tex]

Now that we've found the value of \( x \), we can find the consecutive even integers:

- First even integer: [tex]\( x = -16 \)[/tex]

- Second even integer: [tex]\( x + 2 = -16 + 2 = -14 \)[/tex]

- Third even integer: [tex]\( x + 4 = -16 + 4 = -12 \)[/tex]

- Fourth even integer: [tex]\( x + 6 = -16 + 6 = -10 \)[/tex]

So, the four consecutive even integers with a sum of -52 are -16, -14, -12, and -10.

Answer:

The rate of change determines the average speed of the ball when it is dropped from the building.

Step-by-step explanation:

d(t) = 16t^2

when t = 2

d(t) = 16 (2)²

d(t) = 64

when t = 5

d(t) = 16 (5)²

d(t) = 400

Average speed/rate of change = distance/time = 64/2 = 32 feet

Average speed/rate of change = distance/time = 400/5 = 80 feet

The rate of change determines the average speed of the ball when it is dropped from the building.

!!

The average rate of change of d(t) from [tex]\( t = 2 \) to \( t = 5 \)[/tex] represents that the ball traveled at an average rate of 112 feet per second during this time interval.

The average rate of change of a function over a given interval is calculated by finding the difference in the function values at the endpoints of the interval and dividing by the difference in the independent variable values. In this case, we want to find the average rate of change of the function [tex]\( d(t) = 16t^2 \) from \( t = 2 \) to \( t = 5 \).[/tex]

First, we find the values of the function at the endpoints of the interval:

- At [tex]\( t = 2 \), \( d(2) = 16(2)^2 = 64 \)[/tex] feet.

- At [tex]\( t = 5 \), \( d(5) = 16(5)^2 = 400 \)[/tex] feet.

Then, we calculate the difference in the function values:

[tex]\[ \text{Difference in } d(t) = d(5) - d(2) = 400 - 64 = 336 \text{ feet} \][/tex]

Next, we calculate the difference in the independent variable values:

[tex]\[ \text{Difference in } t = 5 - 2 = 3 \text{ seconds} \][/tex]

Finally, we find the average rate of change by dividing the difference in d(t) by the difference in t:

[tex]\[ \text{Average rate of change} = \frac{\text{Difference in } d(t)}{\text{Difference in } t} = \frac{336}{3} = 112 \text{ feet/second} \][/tex]

Answer:

a- p(x) = 2xy(2x -y)(2x + y)(4x² + y²) ⇒ 2nd answer

b- repeated differences of squares ⇒ 1st answer

Step-by-step explanation:

* Lets explain how to solve the problem

∵ p(x) = 32x^5y - 2xy^5

- The coefficients of the two terms are 32 and 2

∵ 2 is a common factor in 32 and 2

∵ 32 ÷ 2 = 16 and 2 ÷ 2 = 1

∴ p(x) = 2(16x^5y - xy^5)

* Now lets find the common factors of the variables x and y

∵ The common factor is x^5 and x is x

∵ The common factor in y and y^5 is y

∴ the common factors in 16x^5y - xy^5 are xy

∵ 16x^5y ÷ xy = 16x^4

∵ xy^5 ÷ xy = y^4

∴ p(x) = 2xy(16x^4 - y^4)

- Remember that a² - b² is called difference of two squares we

 factorize it by distributed into two polynomials have same terms

 with different middle sign (a + b)(a - b)

∵ 16x^4 - y^4 is a different of two squares because √(16x^4) = 4x²

  and √9y^4) = y²

∴ The factorization of 16x^4 - y^4 is (4x² + y²)(4x² - y²)

∴ p(x) = 2xy[(4x² + y²)(4x² - y²)]

- The bracket 4x² - y² is also different of two squares because

 √(4x²) = 2x and √(y²) = y

∴ The factorization of 4x² - y² is (2x - y)(2x + y)

∴ p(x) = 2xy(2x -y)(2x + y)(4x² + y²)

a- p(x) = 2xy(2x -y)(2x + y)(4x² + y²)

b- The methods used to factor p(x) are:

    greatest common factor and repeated differences of squares

- But you ask to chose one answer of b so chose repeated

Answer:

The system is inconsistent because there is no solution.  

Step-by-step explanation:

I'm going to put both of these in slope-intercept form (y=mx+b where m is slope and b is y-intercept).

3x-6y=20

Solve for y.

3x-6y=20

Subtract 3x on both sides:

  -6y=-3x+20

Divide both sides by -6:

    y=(-3/-6)x+(20/-6)

Reduce:

  y=(1/2)x+(-10/3)

The slope is 1/2 and the y-intercept is -10/3.

2x-4y=3

Solve for y.

2x-4y=3

Subtract 2x on both sides:

   -4y=-2x+3

Divide both sides by -4:

    y=(-2/-4)x+(3/-4)

Reduce:

   y=(1/2)x+(-3/4)

The slope is 1/2 and the y-intercept is -3/4.

The lines are parallel so they have no intersection. I know they are parallel because they have the same slope and different y-intercept.

The system is inconsistent because there is no solution.  

Answer:

B) Inconsistent

Step-by-step explanation:

Step 1: Write both equations

3x - 6y = 20

2x - 4y = 3

Step 2: Find x in terms of y

3x - 6y = 20

x = 20+6y/3

Step 3: Substitute x in one of the equations to find y

2x - 4y = 3

2(20+6y/3) - 5y = 3

40 + 12y - 12y = 9

0 ≠ -31

Therefore, these system of equations have no solution.

Step 4: Choose the option

A) consistent- A consistent system of equations has at least one set of equations. Therefore, this option is incorrect.

B) inconsistent- An inconsistent system of equations has no solution. Therefore, this option is correct.

C) Independent- An independent system of equations has one solution. Therefore, this option is incorrect.

D) Dependent- A dependent system of equations have infinite solutions. Therefore, this option is incorrect.

Option B is the right answer

Answer:

Step-by-step explanation:

You find the number of subsets of a set by using the formula [tex]2^{\text{ number of elements}[/tex].

We have 7 elements so that means we have [tex]2^{7}=128[/tex] subsets.

A set with 7 elements can have 128 subsets, as calculated using the equation 2^n, where n is the number of elements in the set.

In Mathematics, a subset is a portion of a set, including the empty set and the set itself. The number of subsets a set can have is calculated using the equation 2^n, where 'n' is the number of elements in the set. In this case, the set A includes 7 elements, therefore applying the equation we get: 2^7=128 subsets, which is the answer to your question.

For example, {-3, -1, 0} would be a subset of set A, as would {0, 1, 2}, {-2, 0, 2}, and so on. The complete set ({-3,-2,-1,0,1,2,3}) is also a subset, as is the empty set ({}).

A term is any number, variable or combination of a number and a variable in an equation.

Examples:

In 2x + 5y + 8, 2x is one term,  5y is a second term and 8 is a 3rd term.

In the equation 2x + 3 + 5x -2

Combine the like terms 2x and 5x are like terms because they both have x as a variable, there is a plus sign in fron of the 5x, so you would have 2x +5x = 7x

Then 3 and 3 are like terms, because they are just numbers, there is a subtraction sign in front of the 2, so you have 3-2 = 1

Answer:

The larger number is 8

Step-by-step explanation:

Let

x -----> the smaller number

y ----> the larger number

we know that

x+y=10

y=10-x -----> equation A

y=4x -----> equation B

Solve by substitution

substitute equation B in equation A and solve for x

4x=10-x

4x+x=10

5x=10

x=2

Find the value of y

y=4x-------> y=4(2)=8

therefore

The smaller number is 2 and the larger number is 8

To find the larger number where the sum of two numbers is 10 and the larger is four times the smaller, the system of equations y = -x + 10 and y = 4x is used, and through solving, the larger number is determined to be 8.

The question entails finding the larger number when two numbers sum to 10, and the larger number is four times the smaller number. The system of equations representing the scenario is y = -x + 10 and y = 4x. To find the larger number, set these two equations equal to each other since they both equal y:

4x = -x + 10

Now, solve for x by adding x to both sides:

5x = 10

Then, divide both sides by 5:

x = 2

Since x is the smaller number, and y is four times larger, compute y:

y = 4x = 4(2) = 8

The larger number (y) in this case is 8.
