What addition does the model represent 3 + (-1)

Answer:

20

Step-by-step explanation:

The pythagorean theorem states that

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

So [tex]16^2 + 12^2 = c^2\\256+144 = c^2\\400 = c^2[/tex]

You would then do

[tex]400 = c^2\\\sqrt{400} = c[/tex]

Because a square root is the opposite of a square.

[tex]\sqrt{400} = 20[/tex]

because 20 * 20 = 400

Answer:

-x - 8

Step-by-step explanation:

Simplify each term.

   Apply the distributive property.

    5x - 2(3x) - 2 ⋅ 4

    Multiply 3 by -2

    5x - 6x - 2 ⋅ 4

     Multiply -2 by 4

     5x - 6x - 8

Subtract 6x from 5x

 -x - 8

The most common form of explicit proof in highschool geometry is a two column proof consists of five parts: the given, the proposition, the statement column, the reason column, and the diagram (if one is given).

Answer:

Proofs contain given information and a statement to be proven. You use deductive reasoning to create an argument with justification of steps using theorems, postulates, and definitions. Then you arrive at a conclusion.

Answer:

x can be anything. (Infinite solutions)

Step-by-step explanation:

[tex]3\left(x-3\right)+18=3\left(x+3\right)[/tex]

Expand:

[tex]3x-3*3+18=3x+3*3[/tex]

[tex]3x+9=3x+9[/tex]

Subtract 9 from each side:

[tex]3x=3x[/tex]

Subtract 3x from both sides:

[tex]0=0[/tex]

Both sides are equal, and hence this equation is true for any "x" value.

Answer:

MP= (1,-3.5) or written another way MP= (1,[tex]-\frac{7}{2}[/tex])

Step-by-step explanation:

Midpoint formula: [tex]MP= (\frac{x_1+x_2}{2}),(\frac{y_1+y_2}{2} )[/tex]

[tex]MP= (\frac{-5+7}{2}),(\frac{-2+-5}{2})[/tex]  -5+7=2  -2+-5=7

[tex]MP= (\frac{2}{2}),(\frac{-7}{2})[/tex]  2/2=1  -7/2=-3.5

[tex]MP= (1,-3.5)[/tex]  

Answer:

$10

Step-by-step explanation:

The question made is How much did I have? This question is about the amount of money that you had before receiving the money from your mom, dad and aunt and uncle. This means that the answer is the $3 you had plus the other $7 you said you had. So, $3+$7=$10. You had $10.

The FitnessGram Pacer Test is a multistage aerobic capacity test that progressively gets more difficult as it continues. The 20 meter pacer test will begin in 30 seconds. Line up at the start. The running speed starts slowly, but gets faster each minute after you hear this signal. A single lap should be completed each time you hear this sound.  Remember to run in a straight line, and run as long as possible. The second time you fail to complete a lap before the sound, your test is over. The test will begin on the word start. On your mark, get ready, start.

Answer:

m = -11/7

n = -8/7

Step-by-step explanation:

Here, what we want to calculate is the coordinates of the point B

Let’s consider the straight line as A B C

we can see that actually, the point B divides the line into the ratio 2:5 since AB:AC is 2:5

Thus, by using the internal division formula (section formula) with the ratio of division, we can get the coordinates of point B

Mathematically, the formula for internal division is given as follows;

B = ( (mx2 + nx1) /m + n , (my2 + ny1)/( m + n))

From the question;

m:n = 2:5

Thus m = 2, n = 5

(x1,y1) are coordinates of A

x1 = -3 , y1 = -4

(x2, y2) are coordinates of C

x2 = 2 , y2 = 6

Thus, substituting these values into the equation we have;

B ={ 2(2) + 5(-3)}/(2+5) , {2(6) + 5(-4)}/(2+5)

B = (-11/7, -8/7)

Answer:

2:8

Step-by-step explanation:

Answer:

First off, this is a easy question but your answer is 2:8  just divide both numbers in half 8 divided but 2 equals 4 and 2 divided in half is 1

your answer would be 4:1

Step-by-step explanation:

there is 8 black birds and 2 white birds, and to show a different way to show the two is dividing it from 8:2 to 4:1

Answer:

c = a

Step-by-step explanation:

Let k be one of the root of the given equation.

According to the problem,

1/k will be the other root of the given equation.

We know that, product of the roots of the equation = c/a.

Therefore, k × 1/k = c/a.

or, 1 = c/a.

or, a = c [multiplying a on both sides].

The roots of the equation ax2 + bx + c = 0 will be reciprocal if a = c.

Therefore, a = c or c = a.

Answer:

[tex]m=-2[/tex]

Step-by-step explanation:

[tex]3=m+5[/tex]

Switch sides:

[tex]m+5=3[/tex]

Subtract 5 from both sides:

[tex]m+5-5=3-5[/tex]

[tex]m=-2[/tex]

Answer:

-2

Step-by-step explanation:

1. Add the same term to both sides of the equation

3=m+5

( 3-5 = m + 5 -5)

2. Simplify

-subtract the numbers

- add the numbers

3. Solution

-2 = m

Answer:

⇛√2/2.

Step-by-step explanation:

Given that,

√3/√6

The denominator is √6

We know that

The rationalising factor of √a is √a

Therefore, the rationalising factor of √6 is '√6’.

Now,

⇛(√3/6) × (√6/√6)

⇛{√3(√6)}/(√6)(√6)

⇛(√3*6)/(√6)²

⇛(√18)/(6)

⇛(√2*9)/6

⇛(2√2)/6

⇛√2/2

Hence, the denominator is rationalised.

Area of a rectangle = Width * Length

In our problem,

width = 2n^3

length = 7n^2 + 3n

Area = 2n^3 (7n^2 + 3n)

Distribute the 2n^3

Area = 14n^5 + 6n^4

The required, area of the given rectangle is given as 14n⁵ + 6n⁴.

The rectangle is 4 sided geometric shape whose opposites are equal in lengths and all angles are about 90°.

The area of a rectangle is the product of the length and width of the rectangle.

Here,
In the question, we are given,
length = 7n² + 3n
width = 2n³

Area of the rectangle = length × width
Area of the rectangle = 7n² + 3n × 2n³
Area of the rectangle = 14n⁵ + 6n⁴

The required, area of the given rectangle is given as 14n⁵ + 6n⁴.

The equation that represents the set of points that are 8 units from (-8,-7) is  [tex]x_{1} ^{2}[/tex] + 16[tex]x_{1}[/tex] + [tex]y_{1} ^{2}[/tex] + 14[tex]y_{1}[/tex] + 49 = 0.

What is the distance between two points ?

Distance between two points is the length of the line segment that connects the two locations in a plane.

We know that the distance between two points is calculated by using the distance formula which is given as :

D = [tex]\sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2} }[/tex]

Here ; let's assume the first point is (x1, y1). It is given that other point is (x2, y2) = (-8 , -7) and distance D = 8 units. Now use these data to find out the equation :

8  = [tex]\sqrt{(-8 - x_{1})^{2} + (-7- y_{1})^{2} }[/tex]

Squaring on both sides , we get :

64 = [tex](-8 - x_{1} ) ^{2}[/tex] + [tex](-7 - y_{1})^{2} }[/tex]

64 = 64 + [tex]x_{1} ^{2}[/tex] + 16[tex]x_{1}[/tex] + 49 + [tex]y_{1} ^{2}[/tex] + 14[tex]y_{1}[/tex]

[tex]x_{1} ^{2}[/tex] + 16[tex]x_{1}[/tex] + [tex]y_{1} ^{2}[/tex] + 14[tex]y_{1}[/tex] = 64 - 64 - 49

[tex]x_{1} ^{2}[/tex] + 16[tex]x_{1}[/tex] + [tex]y_{1} ^{2}[/tex] + 14[tex]y_{1}[/tex] = -49

or

[tex]x_{1} ^{2}[/tex] + 16[tex]x_{1}[/tex] + [tex]y_{1} ^{2}[/tex] + 14[tex]y_{1}[/tex] + 49 = 0

Therefore , the equation that represents the set of points that are 8 units from (-8,-7) is  [tex]x_{1} ^{2}[/tex] + 16[tex]x_{1}[/tex] + [tex]y_{1} ^{2}[/tex] + 14[tex]y_{1}[/tex] + 49 = 0.
