John had 84 dollars, and his brother Fred owed 12 dollars to his friend. John gave his brother some money. Fred paid his debt and now both of them has the same amount left. How much money did John give Fred? PLZZZZ HELP!!!!!

Answer:

8 units

Step-by-step explanation:

The x coordinates don't change so you just subtract 2 from 10 to get the distance.

Answer:

8

Step-by-step explanation:

To calculate the distance d, using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = A(- 9, 2) and (x₂, y₂ ) = B(- 9, 10)

d = [tex]\sqrt{(-9+9)^2+(10-2)^2}[/tex]

   = [tex]\sqrt{0^2+8^2}[/tex] = [tex]\sqrt{64}[/tex] = 8

QUESTION 1a.

We want to add

[tex]( - 2 {x}^{2} - 4x + 13) + (12 {x}^{2} + 2x - 25)[/tex]

We group similar terms to get

[tex]- 2 {x}^{2} + 12 {x}^{2}- 4x + 2x - 25 + 13[/tex]

Simplify:

[tex]- 10{x}^{2} - 2x -12[/tex]

QUESTION 1b.

The given function is:

[tex](7x^2+4x-26)-(-7x^2-3x+15)[/tex]

Expand the parenthesis to obtain,

[tex]7x^2+4x-26 + 7x^2 + 3x - 15[/tex]

Group similar terms,

[tex]7x^2+7 {x}^{2} + 4x + 3x-26 - 15[/tex]

Simplify:

[tex]14{x}^{2} + 7x-41[/tex]

QUESTION 2

The given function is

[tex]f(n)=n^2-6n-16[/tex]

The zeros of this function is given by;

[tex]n^2-6n-16 = 0[/tex]

Split the middle term.

[tex]n^2-8n + 2n-16 = 0[/tex]

Factor;

[tex]n(n - 8) + 2(n - 8) = 0[/tex]

[tex](n - 8)(n + 2) = 0[/tex]

[tex]n - 8 = 0 \: or \: n + 2 = 0[/tex]

[tex]n = 8 \: or \: n = - 2[/tex]

A. Pi= 22/7 =3.1415....

C. Pi is the ratio to a circles circumference to its diameter

Option: C is the correct answer.

The equation of the blue graph i.e. function G(x) is:

               C.  [tex]G(x)=(x+3)^2+1[/tex]

We are given a parent function F(x) as:

                      [tex]F(x)=x^2[/tex]

Now after looking at the graph of the transformed function G(x) we see that the graph of G(x) is obtained by shifting the graph of F(x) 3 units to the left and  1 units upward.

Hence, the equation of the transformed function G(x) is given by:

                           [tex]G(x)=(x+3)^2+1[/tex]

Answer:

Price of the drink = $1.25

Step-by-step explanation:

4.5% * ( $4.5 + $6.25 + drink) = $0.54

4.5/100 * ( $4.5 + $6.25 + drink) = $0.54

0.045 * ( $4.5 + $6.25 + drink) = $0.54

0.045/0.045 * ( $4.5 + $6.25 + drink) = $0.54/0.045

( $4.5 + $6.25 + drink) = $12

10.75 + drink = $12

drink = $12 - $10.75

drink = $1.25

The price of the drink is $1.25

The given parameters are:

Tax amount = $0.54

Salad = $4.50

Sandwich = $6.25

Let the price of the drink be x.

Given that the sales tax is 4.5%, we have:

4.5% * ( $4.5 + $6.25 + x) = $0.54

Divide both sides by 4.5%

( $4.5 + $6.25 + x) = $12

Evaluate the sum

$10.75 + x= $12

Subtract $10.75 from both sides

x = $1.25

Hence, the price of the drink is $1.25

Final answer:

To make a 40-ounce mixture that is 60% fruit juice, equal amounts (20 ounces each) of 20% fruit juice and 100% fruit juice should be used.

Explanation:

Calculating the Fruit Juice Mixture

To solve this problem, we'll use a system of equations. Let's assume that the amount of 20% fruit juice used is x ounces, and the amount of 100% fruit juice used is y ounces. We are trying to make 40 ounces of a mixture that is 60% fruit juice.

First, the total amount of the mixture should be 40 ounces:

x + y = 40

Second, the total percentage of fruit juice in the mixture should be 60%:

0.20x + 1.00y = 0.60 * 40

Now, let's solve these equations step-by-step:

From the first equation, we can say y = 40 - x.

Substitute y in the second equation: 0.20x + 1.00(40 - x) = 24.

Simplify: 0.20x + 40 - x = 24.

Combine like terms: 40 - 0.80x = 24.

Subtract 40 from both sides: -0.80x = -16.

Divide both sides by -0.80 to find x: x = 20.

Substitute x back into y = 40 - x to find y: y = 20.

Therefore, to achieve a 60% fruit juice mixture, 20 ounces of the 20% fruit juice and 20 ounces of the 100% fruit juice should be combined.

Final answer:

After substituting the x and y values of the point (3,-1) into the circle's equation, it is determined that (3,-1) does not lie on the circle since the equation does not hold true.

Explanation:

To determine if the point (3,-1) lies on the circle given by the equation [tex](x+1)^2 + (y-1)^2[/tex]=16, we must substitute the x and y values of the point into the equation and see if the equation holds true.

Let's plug in x = 3 and y = -1:

[tex](3+1)^2 + (-1-1)^2[/tex]= 16

[tex](4)^2 + (-2)^2[/tex] = 16

16 + 4 = 20

Since 16 + 4 does not equal 16, the point (3, -1) does not lie on the circle

Answer:

the correct answer is -9

Step-by-step explanation:

Answer:

y = -5

Step-by-step explanation:

To solve this, we simply plug in 4 into x and then solve for y. We have:

[tex]-3x+9y=-57\\[/tex]

Now we put 4 into x and do some algebra and solve for the value of y:

[tex]-3x+9y=-57\\-3(4)+9y=-57\\-12+9y=-57\\9y=-57+12\\9y=-45\\y=\frac{-45}{9}\\y=-5[/tex]

So y = -5

It’s a good idea to get into the habit of using parentheses

when substituting numbers in for variables.

If you have parentheses in your original problem, change them to brackets as you substitute (to avoid confusion).

Now plug in the values for b and c into the problem.

So we have [(-5) + (-3)].

Simplifying inside the brackets, we get [(-8)].

So -8 is the answer.

Step-by-step explanation:

Surface Area Formula: SA=2lw+2lh+2hw

SA is surface area. l is length, w is width, h is height. Make sure to follow PEMDAS and keep multiplication together before adding.

Now substitute values

2(12 3/4*8 1/2)+ 2(12 3/4 * 5 1/2)+ 2(5 1/2*8 1/2)

SA=450.5 inches squared

To find the total surface area of three identical boxes with given dimensions, calculate the surface area of one box using the formula for a rectangular prism and then multiply by three. The total surface area of three boxes is 1351.5 square inches.

Calculating the Total Surface Area of Three Boxes

The question involves finding the total surface area of three identical boxes, each with the dimensions 8 1/2 inches wide, 12 3/4 inches long, and 5 1/2 inches tall. To calculate the surface area of one box, we use the formula for surface area of a rectangular prism:

SA = 2lw + 2lh + 2wh

where SA is the surface area, l is the length, w is the width, and h is the height. Convert fractions to decimals for easy calculation:

Width (w) = 8.5 inches

Length (l) = 12.75 inches

Height (h) = 5.5 inches

Applying the dimensions:

SA = 2(12.75)(8.5) + 2(12.75)(5.5) + 2(8.5)(5.5)

Calculate and add up the areas for each pair of sides:

SA = 2(108.375) + 2(70.125) + 2(46.75)

SA = 216.75 + 140.25 + 93.5

Sum to find the total surface area for one box:

SA = 450.5 square inches

To find the total surface area for three boxes, multiply the surface area of one box by 3:

Total SA = 450.5 * 3

Total SA = 1351.5 square inches

The total surface area of three such boxes is 1351.5 square inches.
