Could someone create Equations & Explanations based on this question, because I need to solve using substitution and later modify it to create a system of inequalities.

Answer:

Step-by-step explanation:

It adds by negative 5 because if you add up all of the math and equations, it will all fit together.

Here's an example.

The first one is 3 and -2, so lets add -2 by 5.

-2 + 5 = 3 --- 1st row

We can figure this out by subtracting 2 by 5, which equals 3.

( This does not apply to all equations. )

Let's add all of them by 5 now.

-7 + 5 = -2 --- 2nd row

-12 + 5 = -7 --- 3rd row

On the last row, we add -12 by -5 and you get -17.

-17 + 5 = -12 --- 4th row

That's how you figure it out.

Hope this helps! <3

Answer: 390 miles

Step-by-step explanation:

Reggie ran for half an hour in the morning and half an hour in the evening.

That is a total of 1 hour for the day.

He runs 6.5 miles in one hour.

In 60 days he would have ran;

= 60 * 6.5

= 390 miles

Answer:

A polygon is a very big catagory. For example, a triangle has three sides, while a quadrilateral has four sides.

A triangle would be, A=h*w/2 (h being hight, and w being width)

A quadrilateral would be, A=h*w

Answer:

2 looks good  I & IV

Step-by-step explanation:

Answer:

3Ax-6x = 15

3x(A-2)=15

If A were 2, the left side of the equation would be 0 and it wouldn't equal 15 no matter what the value of x is. So A is 2

So the equation is:

If you think it is not 34°, then your question must be asking to find something else (e.g. angle D, which is 68°)

Answer:

hi its 3.501

Step-by-step explanation:

Answer:

x = 2, y = -1

Step-by-step explanation:

To solve this with elimination, we first multiply the first equation by -2.5

Our new equations are:

-5x - 7.5y = -2.5

5x – 4y = 14

After adding these two equations together, the x cancels out and we have:

-11.5y = 11.5

Divide both sides by -11.5

y = -1

Plugging this value into y in one of the equations we have:

2x + 3y = 1

2x + 3(-1) = 1

2x - 3 = 1

Add 3 to both sides

2x = 4

Divide both sides by 2

x = 2

Answer:

I believe they are equal but I'm not for sure

Answer:

x= -14

Step-by-step explanation:

-x+3x-x=-8-6

x= -14

-x+8+3x=x-6

the first thing we need to do is move the x's to the left and the numbers to the right

when moving a number from one side to another it's sign is changed

-x+3x-x=-6-8

x=-14

Answer: 32

Step-by-step explanation:

The expression that is equivalent to 2^2 divided by 2/2^4 would be calculated as:

= 2^2 ÷ 2/2^4

= 4 ÷ 2/16

= 4 ÷ 1/8

= 4 × 8

= 32

The expression would be equal to 32 based on the above calculation

Answer:

The width of rectangle w = 4 units

Step-by-step explanation:

We are given:

Width of rectangle = w

Length of rectangle = w+ 4

Area of rectangle = 32 units

We need to find width of the rectangle

The formula used is: [tex]Area\:of\:rectangle=Length\times Width[/tex]

Putting values and finding width of rectangle

[tex]Area\:of\:rectangle=Length\times Width\\32=(w+4)\times w\\32=w^2+4w\\w^2+4w-32=0[/tex]

We need to solve this quadratic equation to find width (w)

We will use factorisation and break the middle term.

[tex]w^2+4w-32=0\\w^2+8w-4w-32=0\\w(w+8)-4(w+8)=0\\(w-4)(w+8)=0\\w-4=0\:or\:w+8=0\\w=4\:or\:w=-8[/tex]

Since width of rectangle can't be negative, so rejecting w=-8

Therefore, the width of rectangle w = 4 units

f(x) and g(x) are not closed under subtraction because when subtracted, the result will be a polynomial, the correct option is B.

According to Closure Property, when something is closed, the output will be same as the input.

The polynomials f(x) and g(x) can be seen in the image.

On subtracting the two polynomials, the output will be a polynomial and so it is closed under subtraction.

b. x = 4

Step-by-step explanation:

a.  [tex]\frac{2x}{3}=8[/tex]

Multiply both sides by 3;

[tex]\frac{2x}{3} *3=8*3\\\\2x=24[/tex]

Divide both sides by 2;

x = 12

b.  [tex]\frac{3x}{2}=6[/tex]

Multiply both sides by 2;

Divide both sides by 3;

x = 4

Answer: $3,000.

Step-by-step explanation: The 10% of $15,000 is %1,500, so the value of the car drops by $1,500 each year. So, in eight years (8 years x $1,500), the value will drop by $12,000. Therefore, the price of the car in eight years will be the original amount minus the depreciating amount ($15,000 - $12,000), this will be $3,000.

Responder:

1) x² + y²-8x + 10y + 16 = 0

2) x² + y² + x + 18y + 33 = 0

Explicación paso a paso:

A partir de la pregunta, debemos expresar la ecuación en la forma estándar de un círculo expresado como;

x² + y² + 2gx + 2fy + c = 0 donde;

(-g, -f) es el centro.

1) Para la ecuación (x-4) ² + (y + 5) ² = 25

Expande el paréntesis;

(x-4) ² + (y + 5) ² = 25

x²-8x + 16 + y² + 10x + 25 = 25

x²-8x + 16 + y² + 10y + 25-25 = 0

Recopile términos similares;

x² + y²-8x + 10y + 16 + 0 = 0

x² + y²-8x + 10y + 16 = 0

Por lo tanto, la ecuación requerida es x² + y²-8x + 10y + 16 = 0

2) Para la expresión (x + 1) ² + (y + 9) ² = 49

x² + x + 1 + y² + 18y + 81 = 49

x² + x + 1 + y² + 18y + 81-49 = 0

Recopile términos similares;

x² + y² + x + 18y + 82-49 = 0

x² + y² + x + 18y + 33 = 0

Por tanto, la ecuación requerida es x² + y² + x + 18y + 33 = 0

Answer:

7.21 (7.211103 exact)

Step-by-step explanation:

In this question, we have to find the distance of the two points.

To do so, we would use this equation: d = √(x2-x1)² + (y2-y1)²

Plug in your coordinates and solve:

d = √(4+2)² + (7-3)²

d = √(6)² + (4)²

d = √36 + 16

d = √52

Now, get the square root of 52:

d = 7.211103

The distance of each coordinate would be around 7.21

Simplify

Combine like terms

3=9

Divide both sides of the equation by the same term

3=9

Answer:

13

Step-by-step explanation:

Is there more info to this problem? I'm assuming both triangles are congruent. If so then you can assume that BC = CD

If that's the case then set them equal to each other to solve for x then plug x back into the side for CD to get the value

6x-5 = 4x+1

2x = 6

x = 3

Plug into CD   4(3) +1

= 13
