Final answer:

The ratio of Russel's weight to Brooke's weight, given that Russel's weight is 3/4 of Brooke's, is 3:4.

Explanation:

The student is asking how to find the ratio of Russel's weight to Brooke's weight given that Russel's weight is 3/4 of Brooke's weight. To find this ratio, it's straightforward since the value 3/4 already represents the ratio of Russel's weight to Brooke's weight.

Therefore, the ratio of Russel's weight to Brooke's weight is 3:4. This simply means that for every 3 parts of weight that Russel has, Brooke has 4 parts of weight. Ratios are usually expressed in simplest form, and since 3/4 is already in its simplest form, we use it as it is.

Solutions to systems of equations are typically found at the point where the lines intersect on a graph. For linear equations, this is represented by the equation y = mx + b. Quadratic equations also have solutions known as roots, and ones based on physical data typically have real, positive roots.

Due to the incomplete equation and graph not provided, we can first discuss general methods for finding solutions to systems of equations. One common method is the intersection of two lines on a graph, which illustrates the system of equations. Here, the zeros on the two-dimensional (x-y) graph represent the solution to the equations:

In this scenario, the y-axis represents the variable V, and the x-axis represents the variable X. The primary task is to find the point where these two lines intersect on the graph - this is the solution to the system of equations. The equation of a line is typically a linear equation, represented as y = mx + b, where m is the slope and b is the intercept.

If the equations are quadratic, these also have solutions, known as roots. Quadratic equations constructed on physical data always have real roots, but often only those having positive values are of any significance.

Without the specifics of your graph, an exact solution cannot be provided.

Answer:

Do you still need help with this? If so just say if you do in the comments and I can probably help.

Step-by-step explanation:

Hey there!

Let's start by solving for x.

Take the first equation, y = -3x - 7, and substitute in the second equation, y = x + 9, for y.

We now have:

x + 9 = -3x - 7

Add 3x to both sides.

4x + 9 = -7

Subtract 9 from both sides.

4x = -16

Divide each side by 4.

x = -4

Let's use the second equation, y = x + 9, to solve for x.

Put in the value we just solved for.

We now have:

y = -4 + 9

Simplify.

y = 5

Let's check our answer, starting with the first equation, y = -3x - 7.

Put in the values for x and y.

5 = -3(-4) - 7

5 = 12 - 7

5 = 5

Do the same with the second equation, y = x + 9.

5 = -4 + 9

5 = 5

The solution to the system of equations is (5, -4).

Hope this helps!

Answer:

(-4, 5)

Step-by-step explanation:

Since y = -3x - 7 in the first equation, substitute y of the second equation with -3x - 7:

-3x - 7 = x + 9

Subtract x from both sides. Add 7 to both sides.

-4x = 16

Divide both sides by -4.

x = -4

Now, substitute -4 for x in the second equation.

y = -4 + 9

y = 5

The solution is:

x = -4; y = 5

As an ordered pair, the solution is:

(-4, 5)

Replace x^2 with m

Step-by-step explanation:

x^8-3x^4+2=0

We want to write this as a quadratic, which means as am^2+bm +c

x^8  needs to become m^2

Let m = x^4

Then m^2 = x^4^2 = x^8

Our equation becomes

m^2 -3m +2 =0

Replace x^2 with m

Answer:

Replace x with  [tex]y^{1/4}[/tex]

Step-by-step explanation:

The general  form of a quadratic equation is  [tex]ax^{2}[/tex] + bx + c.

To  find a substitution  we have to think of a way of substituting ‘x’ to make it have a power of 2,

Here, we will use [tex]y^{1/4}[/tex]  

[tex]x^{8}[/tex] - [tex]3x^{4}[/tex] +2 = 0

let x = [tex]y^{1/4}[/tex]

so it gives

([tex]y^{1/4}[/tex])^8 – 3( [tex]y^{1/4}[/tex] )^4 +2 = 0

[tex]y^{2}[/tex] – 3y + 2 = 0

Solving the equation

[tex]y^{2}[/tex]  - 2y – y + 2 =0

([tex]y^{2}[/tex] – 2y) -1(y – 2) = 0

y(y - 2) -1(y - 2) = 0

(y-1) (y-2)

:- y = 1 or y = 2

Since x = [tex]y^{1/4}[/tex]  

When y = 1

X = [tex]1^{1/4}[/tex]

X = [tex]4\sqrt{1}[/tex]

X = 1

and when  y = 2

X = [tex]2^{1/4}[/tex]

X = [tex]4\sqrt{2}[/tex]

X = 1.1892...

Answer:

Part A) The legs have already been given. I’m looking for the hypotenuse

Part B) [tex]c^{2}=40^{2} +71.5^{2}[/tex]

Part C) The missing length is [tex]81.93\ in[/tex]

Part D) [tex]82\ in[/tex]

Step-by-step explanation:

Part A) What parts of the right triangle have you been given? Are you looking for a leg or the hypotenuse?

we know that

Applying the Pythagoras Theorem

[tex]c^{2}=a^{2} +b^{2}[/tex]

where

c ----> is the hypotenuse of the right triangle

a and b -------> are the legs of the right triangle

In this problem we have

[tex]a=40\ in[/tex]

[tex]b=71.5\ in[/tex]

so

The legs have already been given. I’m looking for the hypotenuse

Part B) Set-up your equation by substituting the correct numbers in to the formula

we have

[tex]a=40\ in[/tex]

[tex]b=71.5\ in[/tex]

substitute in the Pythagoras Theorem and solve for c (hypotenuse)

[tex]c^{2}=40^{2} +71.5^{2}[/tex]

Part C) Solve for the missing length

we have

[tex]c^{2}=40^{2} +71.5^{2}[/tex]

solve for c

[tex]c^{2}=1,600 +5,112.25[/tex]

[tex]c^{2}=6,712.25[/tex]

[tex]c=\sqrt{6,712.25}\ in[/tex]

[tex]c=81.93\ in[/tex]

Part D) What is the size of the television rounded to the nearest whole inch (whole number)?

[tex]81.93=82\ in[/tex]

The Pythagorean Theorem is used to find the size of the TV, which is the hypotenuse in this scenario and equals to approximately 82 inches when rounded to the nearest whole inch.

Since we've set up our equation as 71.5^2+40^2=c^2, we can now simply solve for c, which is our hypotenuse, and in this case, represents the size of the television.

To do so, calculate the square of both given sides and add them: (71.5)^2 + (40)^2 = 5112.25 + 1600 = 6712.25.

The next step is to take the square root of that sum to get the length of the hypotenuse/c: sqrt(6712.25) = ~81.94 inches

Part D: Now, to answer the final part of your question, if we round this result to the nearest whole inch, we get 82 inches as the size of the new television.

[tex]\large\boxed{f(x)=(x+8)^2-110}[/tex]

Step-by-step explanation:

[tex]\text{The vertex form of equation}\ y=ax^2+bx+c:\\\\y=a(x-h)^2+k\\\\\text{We have the equation:}\\f(x)=x^2+16x-46=x^2+2(x)(8)-46=x^2+2(x)(8)+8^2-8^2-46\\\\\text{use}\ (a+b)^2=a^2+2ab+b^2\to x^2+2(x)(8)+8^2=(x+8)^2\\\\f(x)=(x+8)^2-64-46=(x+8)^2-110[/tex]

The function f(x)=x^2+16x-46 can be rewritten by completing the square to achieve the vertex form of the function: f(x)= (x+8)^2 - 110. After rewriting, we can determine the vertex of this parabola is located at (-8,-110).

The problem asks you to rewrite the function f(x)=x^2+16x-46 by completing the square. This involves manipulating the quadratic formula to write it in the form f(x)=a(x-h)^2+k where (h,k) is the vertex of the parabola.

So, let's start by rearranging the original function:

f(x)=x^2+16x-46

The coefficient of x is 16; halving this, we get 8. Then we add and subtract (which means adding 0, so we don't change the equation) this within the square to complete the square:

f(x)= (x^2+16x+64) - 64 - 46

Then, the equation can be written as:

f(x)= (x+8)^2 - 110

This is the vertex form of the function. We can see that the vertex of the parabola is at (-8,-110).

Valerie's monthly income tax payment is $235.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Now, Based on Valerie's annual salary of $24,000, her monthly salary would be,

$24,000 / 12

$2,000

Hence, To calculate her income tax, we first need to determine how much of her earnings are over $944.

⇒ $2,000 - $944

⇒ $1,056

Thus, Valerie's earnings over $944 are $1,056.

Next, we'll calculate the income tax on that amount.

$1,056 x 0.15 = $158.40

So Valerie pays $158.40 in income tax each month.

Additionally, she pays a fixed amount of $76.60 each month, which brings her monthly total to:

⇒ $158.40 + $76.60 = $235.

Therefore, Valerie's monthly income tax payment is $235.

Step-by-step explanation:

Part A: You can solve the equations for an x value which make both true. You do this by setting each equation equal and using inverse operations.

2x = 4x - 2

2x - 4x = 4x - 4x - 2

-2x = -2

x = 1

Part B: You can make a table by substituting the values -4 to 4 in each equation and simplifying.

x     y = 2x      y = 4x - 2

-4           -8            -18

-3           -6             -14
