Answer:

(5b-6)^2

Step-by-step explanation:

by using formula

(a-b)^2 = (a)^2 - 2(a)(b) + (b)^2

by putting values in the above formula

(5b)^2 - 2(5b)(6) + (6)

(5b-6)^2 answer

Answer:

(5b - 6)(5b - 6)

Step-by-step explanation;

25b^2 - 60b + 36

=> (5b)^2 - 2 × 5b × 6 + (6)^2           [Using (a + b)^2 = a^2 + b^2 + 2ab]

=> (5b - 6)^2

=> (5b - 6)(5b - 6)

Answer:

n=3   n=5

Step-by-step explanation:

|4n−15|=|n|

Positive

4n−15=n

Subtract 4n from each side

-15 = -3n

Divide by -3

-15/-3 = n

5 = n

negative

4n -15 = -n

Subtract 4n from each side

-15 = -5n

Divide by -5

-15/-5 = n

3 = n

Answer:

n=3 and n=5

Step-by-step explanation:

|4n−15|=|n|

we know either

4n-15=-n        or 4n=15=n

4n+n=15              4n-n=15

5n=15                     3n=15

n=15/5=3                 n=15/3=5

Step-by-step explanation:

The vertex is always in the middle.

Answer:

2d(b-c)+b=a

Step-by-step explanation:

First you start off with the equation given

2d=(a-b)/(b-c)

Second, you want to start getting A by its self so that means you have to multiply both sides by (b-c) to get (a-b) by its self. (underlined portion cancles out)

2d(b-c)=((a-b)/(b-c)) (b-c) ----> 2d(b-c)=a-b

Finally, you want to add b to both sides to get a completely by it's self. (underlined portion cancles out)

2d(b-c)+b=a-b+b -----> 2d(b-c)+b=a

Answer:

The correct option is;

D) Neither the domain restriction nor the expression for f⁻¹(x) is correct

Step-by-step explanation:

The given function can be written as follows;

f(x) = x² - 331

The inverse of the function f(x), which is f⁻¹(x), can be found as follows;

Let f(x) = x² - 331 = y, we have;

f(x) + 331 = x²

x = √(f(x) + 331)

We replace x with f⁻¹(x) and f(x) with x, to get;

f⁻¹(x) = √(x + 331)

We note that the domain of the inverse function will include values from x ≥ -331, and the correct inverse function √(x + 331) ≠ √x - 331

Therefore, we have that neither the domain restriction nor the expression for f⁻¹(x) is correct.

Answer:

B) The domain restriction is correct, but the expression for f–1(x) is not.

Answer:

Stephon can buy total 4 chips bag and 2 candy bar

Given as :

The money which Stephon has in his pocket = $ 12

The cost of one chips bag = $ 2.25

The cost of one candy bar = $ 1.50

The total number of items he can buy = 6

So, Let the number of chips bag he can buy = x

∴ The number of candy bar he can buy = 6 - x

Now, according to question

The number of chips bag×The cost of one chips bag + The number of candy bar×The cost of one candy bar = $ 12

Or, x × $ 2.25 + (6-x) × $ 1.50 = $ 12

Or,  x × $ 2.25 + 9 -  x × $ 1.50 = $ 12

or,  x × $ 0.75 = 12 - 9

or, x =  = 4

The number of chips bag he can buy = x = 4

And The number of candy bar he can buy = 6 - x = 6 - 4 = 2

Hence Stephon can buy total 4 chips bag and 2 candy bar .  

Answer:

Neither

Step-by-step explanation:

-2x+2y=20

First, you need to transfer the [-2x+2y=20] equation to slope intercept form. First, get the y variable on one side by subtracting -2x from the left side.

So then you have

2y= 2x+20

Then you divide the 2 from the y on BOTH side

y= x+10

Now compare the slope of both equations

y= -1/2x+10 (slope= -1/2)

y=x+10 (slope= 1)

Since the parallel slope to -1/2 is the same slope

Since the perpendicular slope to -1/2 is equal to 2/1 or 2,

Neither of them work

Answer:

Step-by-step explanation:

sqrt(80b^2) can be also written as sqrt(16(5)b^2).

The property sqrt(x*y) = sqrt(x) * sqrt(y) allows us to factor out square root of 16. Thus,

sqrt(16) * sqrt(5) * sqrt (b^2)

4*sqrt(5)*sqrt(b^2)

Sqrt(b^2) is the same as b^2/2, so Sqrt(b^2)= b

final answer 4b * sqrt(5)

Answer:

Carlos could play a total of 15 games

Step-by-step explanation:

In the grand opening of JoJo's arcade:

First 3 games are free

75 cents after the first 3 free games

Carlos has $9 saved from his allowance

75 cents = $0.75

Number of games Carlos could play = Total saved allowance / cost per game after 3 free games

= $9 / $0.75

= 12 games

Total number of games Carlos could play = free games + games from his allowance

= 3 + 12

= 15 games

Carlos could play a total of 15 games

Answer:

No, because 4/8*2= 8/16

And 8/16 is greater than 5/16

Answer:

The statement is false.

Step-by-step explanation:

The easiest way to answer this question is to make both fractions have the same common denominator.  In this case, we should alter the first fraction to have a denominator of 16 so that it matches the second fraction.  To do this, we should multiply both the numerator and the denominator of the fraction by 2 (this is the same as multiplying by 1, which does not change the value of the fraction).  This is modeled below:

4/8 * 2/2 = 8/16

Now, we can plug this value back into our original statement.

8/16 < 5/16

From comparing the numerators, we know that 5 is NOT greater than 8, so the statement is false.

Hope this helps!

Answer:

No, there is no relationship

Step-by-step explanation:

Since there are no pairs of integers, I will give a general answer.

The distance between any two numbers is the absolute value of their difference.

For example we need a distance between numbers of x and y, then we just subtract them in any order and take absolute value of it:

or

There is no relationship between the sum of the numbers.

It would make sense only in case one of the numbers is zero. Then the sum or difference would be same.

Answer:

x = 30

Step-by-step explanation:

The perimeter is the sum of all of the sides of a shape. Therefore, because the sum is equivalent to 104 inches and we are given the lengths of all three sides, we can add the three sides together and set them equal to 104 in order to solve for x.

(x + 3) + (x + 4) + (x + 7) = 104 Drop the parentheses.

x + 3 + x + 4 + x + 7 = 104 Combine like terms (variables first!).

3x + 3 + 4 + 7 = 104 Now, combine constant terms.

3x + 14 = 104 Subtract 14 from both sides.

3x = 90 Divide by 3 on both sides of the equation.

x = 30

Answer:

3/4

Step-by-step explanation:

The mean of a data set is synonymous with the average. To find the mean, add up all the values in the data set and then divide by the number of elements.

From the table, there is 12 values. Thus, add up all the 12 values and then divide by 12:

[tex]\bar x=\frac{(-3)+4+8+(-1)+(-4)+(-2)+0+2+5+2+(-3)+1}{12}[/tex]

Simplify:

[tex]\bar x=\frac{9}{12}[/tex]

Reduce:

[tex]\bar x=3/4[/tex]

Therefore, the mean of the data set is 3/4.

For the data set, this means that the average person guesses the temperature too high by about 3/4°F.

(Note: the symbol of x with a bar over it denotes the mean of a set)

It is 72 because 24 * 3 = 72. The Number is 14

Answer:

y = (2/5)x + 2

Step-by-step explanation:

To find the inverse of a function, we simply exchange the variables x and y and solve for y.

For this function we will write it as such:

y = -5 + (5/2)x

So to find the inverse, we will swap the x and y and solve.

y = -5 + (5/2)x

x = -5 + (5/2)y

x + 5 = (5/2)y

(2/5) * (x + 5) = y

(2/5)x + (2/5)5 = y

(2/5)x + 2 = y

Thus the inverse of the function is:

y = (2/5)x + 2

14

Let me know if this helps :)

Answer: 14

Step-by-step explanation: It’s a good idea to get into the habit of

using parentheses when substituting numbers in for variables.

Since a = 9 and b = 4, 2a - b is 2(9) - (4).

Now think about your order of operations.

Multiplication comes before subtraction so first multiply 2(9) to get 18.

So we have (18) - (4) which is 14.

Answer:

y = -1.0

Step-by-step explanation:

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operations, and =

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

First, add 4y and subtract 14 from both sides:

1y (+4y) + 14 (-14) = -4y (+4y) + 9 (-14)

1y + 4y = 9 - 14

Combine like terms:

5y = -5

Isolate the variable, y. Divide 5 from both sides:

(5y)/5 = (-5)/5

y = -5/5

y = -1

y = -1 is your answer.

Answer:

She is 90 feet above ground before she begins to descend.

She descends by a rate of 5 feet per second.

Step-by-step explanation:

She is 90 feet above ground before she begins to descend. You can see that by looking at the y value of the highest point of the line, which is just between 80 and 100, which is 90.

We can find the rate of her descending by finding the slope. Remember that the slope formula is (y1-y2)/(x1-x2)

We can find two points on the line and plug the x and y values in. Let's use the points (0, 90) and (16, 10).

We plug the values in:

(90-10)/(0-16)

(80)/-16

-5

The slope is negative, which makes sense, because Aretha is descending and not ascending.

So, she is descending by a rate of 5 feet per second.

I hope this helps you!
