The midpoint of A (-4, 2) and B(8,5) is
(2, 7/2)
(-6, 3/2)
(4, 7/2)

Answer:

Whats the question?

Step-by-step explanation:

Area of a triangle is 1/2 x base x height.

The base is 6 units long and the height is 4 units.

Area = 1/2 x 6 x 4 = 12 square units.

The dots do not form a straight line, there is a small curve.

The dots do move up and to the right which makes it a positive curve.

The answer would be B. nonlinear positive association.

Answer:

The smallest number that is in the domain of fog is 3

Step-by-step explanation:

f(x) = [tex]\sqrt{8x}[/tex] (as corrected in comments)

g(x) = x-3

we need to find fog = f(g(x))

For finding f(g(x)) we put the value of g(x) inside the f(x)

f(g(x))=[tex]\sqrt{8(x-3)}[/tex]

The domain of this function is x ≥ 3

because if value of x is less than 3 than the result would be negative and we know √f(x) ≥ 0

So, the smallest number that is in the domain of fog is 3

Answer:

Pythagorean Theorem

hypotenuse^2 = side^2 + side^2

16^2 = 7^2 + side ^ 2

256 - 49 = side^2

side x = sq root (207)

207 = 9 * 23 Therefore,

side x = 3 * sq root (23)

answer is A

Step-by-step explanation:

Answer:

20

Step-by-step explanation:

If the three numbers are x, x+1, and x+2, then:

x (x+1) (x+2) = 990

x (x² + 3x + 2) = 990

x³ + 3x² + 2x - 990 = 0

(x - 9) (x² + 12x + 110) = 0

Since x must be a whole number, x = 9.  You can also use simple trial and error to find that the three numbers are 9, 10, 11.

The sum is:

9 + 10 + 11 = 20

Answer:

4xy[2xy - x - 3]

Step-by-step explanation:

When finding the Greatest Common Factor [GCF], along with the coefficient, you have to factor out the least degree term possible, which in this case is 4xy. This is because although all terms have y and x, their degrees are not all similar, so we have to go with 4xy.

Answer:

-1

Step-by-step explanation:

Given equation of line is:

x - y = 8

In order to find the slope of other line we have to convert the given equation in standard form

So,

-y = -x + 8

Multiplying the equation with -1

y = x - 8

The co-efficient of x is the slope of the line.

Here the co-efficient is 1 so the slop of line is 1.

We know that the producct of slopes of perpendicular lines is -1.

Let m2 be the slope of the other line then

1 * m2 = -1

m2 = -1

So the slope of line perpendicular to line x-y = 8 will be: -1 ..

Answer:

d

Step-by-step explanation:

Given the 2 equations

2x - y = 11 → (1)

3x - 2y = 6 → (2)

Multiply (1) by - 2 and adding will eliminate y

- 4x + 2y = - 22 → (3)

Add (2) and (3) term by term

(3x - 4x) + (- 2y + 2y) = (6 - 22)

- x = - 16 ( multiply both sides by - 1 )

x = 16

Substitute x = 16 into (1) or (2) for corresponding value of y

(1) : 32 - y = 11 ( subtract 32 from both sides )

- y = - 21 ( multiply both sides by - 1 )

y = 21

Solution is (16, 21 ) → d

Answer:

It's d. (16,21).

Step-by-step explanation:

2x -  y =  11 .............(1)

3x – 2y = 6...........(2)

Multiply the first equation by -2:

-4x + 2y = -22.......(3)

Adding (2) + (3):

-x = -16

x = 16.

Substitute for x in equation (1):

2(16)  - y = 11

-y = 11-32 = -21

y = 21.

92 boxes

1379/15=91.93 but u need a full box so 92

Answer:

92

Step-by-step explanation:

Given:

Number of Paperweights = 1,379

Number of Paperweights that each box can hold = 15

Number of boxes needed = 1379 ÷ 15 = 91.933 boxes

Because 0.933 of a box is of no use to anyone, we simply round this number up to the next whole box and just have the last box partially full.

This gives us 92 boxes.

Answer:

I believe it's 22/15

Step-by-step explanation:

17x -6 + 3x - 5 = 1x + 11 + 4x first you add the 17x and 3x and 1x and the 4x

which it would be: 20x - 6 -5 = 5x + 11;

20x - 11 = 5x + 11,

 -5            -5

15x - 11 = 11

      +11   +11

15x = 22

15       15     Divide

x = 22/15

Answer:

C

Step-by-step explanation:

Since the triangle is right with hypotenuse QR

Use Pythagoras' identity to solve for QR

The square on the hypotenuse is equal to the sum of the squares on the other two sides, that is

QR² = 8² + (8[tex]\sqrt{3}[/tex] )²

       = 64 + 192

       = 256 ( take the square root of both sides )

QR = [tex]\sqrt{256}[/tex] = 16

Final answer:

The length of QR is approximately 2.25 units. Since qr and qs are similar, the length of QR is also approximately 2.25 units.

Explanation:

The length of QR can be determined based on the given information about the vectors near S, R, and T. The vectors near S start at about 6 units away, while vectors near R and T start at about 4 units. Using the equation qr|d² = qs|D², we can find that as|¶R = D² / d² = 36 / 16 = 2.25. Since qr and qs are similar, the length of QR is also approximately 2.25 units.

Answer:

Δ = 60

Step-by-step explanation:

Given a quadratic in standard form : ax² + bx + c = 0 : a ≠ 0

Then the discriminant

Δ = b² - 4ac

Given

3x² + 6x = 2 ( subtract 2 from both sides )

3x² + 6x - 2 = 0 ← in standard form

with a = 3, b = 6 and c = - 2

b² - 4ac = 6² - (4 × 3 × - 2) = 36 - (- 24) = 36 + 24 = 60

Answer:

The coordinates of vertex A" is (3 , 1)

Step-by-step explanation:

* Lets revise The translation of a point

- If the point (x , y) translated horizontally to the right by h units

 then the new point = (x + h , y)

- If the point (x , y) translated horizontally to the left by h units

 then the new point = (x - h , y)

- If the point (x , y) translated vertically up by k units

 then the new point = (x , y + k)

- If the point (x , y) translated vertically down by k units

 then the new point = (x , y - k)

* Now lets solve the problem

∵ Δ ABC has a vertex A = (-4 , 2)

∵ The Δ ABC is translated 2 units right and 5 units down to form

   triangle A′B′C′

- From the rule above the x coordinate id added by 2 and the

 y-coordinate is subtracted by 5

∴ A' = (-4 + 2 , 2 - 5) = (-2 , -3)

∴ The image of vertex A is A' = (-2 , -3)

∵ Δ A'B'C' is then translated 5 units right and 4 units up to form

   triangle A″B″C″

- From the rule above the x coordinate is added by 5 and the

 y-coordinate is add by 4

∴ A" = (-2 + 5 , -3 + 4) = (3 , 1)

* The coordinates of vertex A" is (3 , 1)

Answer:

The satisfaction level gained when a customer consumes a product is total utility.It calculated by finding the total sum of utility from consumption.

Marginal utility is the rate of change of total utility and quantity consumed.

Here you apply the expression, Marginal utility=change in total utility/change in quantity consumed

Let, Marginal utility=MU

Total utility=TU

Quantity consumed=QC

Then MU=ΔTU ÷Δ QC

Given the table

Answer:

20 , 20 , 30 will produce a triangle

Step-by-step explanation:

* Lets study how to know if the lengths of the three segments

 can formed a triangle

- It is a fact that in any triangle the sum of the smallest two sides

 must be greater than the largest side

- Lets study some examples

# If the lengths of the three segments are 5 , 6 , 7

∵ 5 and 6 are the smallest

∴ 5 + 6 = 11

∵ 11 > 7 ⇒ the sum greater than the 3rd side

∴ 5 , 6 , 7 can formed a triangle

# If the lengths of the three segments are 5 , 7 , 12

∵ 5 and 7 are the smallest

∴ 5 + 7 = 12

∵ 12 = 12 ⇒ the sum equal the 3rd side

∴ 5 , 7 , 12 can not formed a triangle

# If the lengths of the three segments are 10 , 12 , 24

∵ 10 and 12 are the smallest

∴ 10 + 12 = 22

∵ 22 < 24 ⇒ the sum less than the 3rd side

∴ 10 , 12 , 24 can not formed a triangle

* Now lets solve the problem

∵ The length of the three segments are 20 , 20 , 30

∵ 20 and 20 are the smallest

∴ 20 + 20 = 40

∵ 40 > 30 ⇒ the sum greater than the 3rd side

∴ 20 , 20 , 30 will produce a triangle

Answer:

86

Step-by-step explanation:

Since something minus a negative is just adding, we get 37-(-8)=37+8 or 45. We can do the same with 11-(-30) which is 11+30 or 41. So 45+41=86

Answer:

86.

Step-by-step explanation:

Work out the 'inner' parentheses first:

(37 - (-8)] + [11 - (-30)]

= (37 + 8) + (11 + 30)

Now the outer parentheses:

= 45 + 41

= 86.

Answer:

199

Step-by-step explanation:

For this problem, you have to write an formula.

a(n)=a(1)+(n-1)d

n is the term you are trying to find (in this case it's 50).

a(1) is the first term in the sequence (in this case it's 3).

d is the common difference (in this case it's 4).

Plug those in, and you get:

a(50)=3+(50-1)4

And you can easily solve that and get a(50)=199.

Answer:

199

Step-by-step explanation:

Hello There!

X=2

To solve this, we first need to understand that when we see an X in parentheses, we multiply the number before it in this case 4 by X.

The answer is 2 because we multiply 4 by 2 which is the x value so 4*2 is equal to 8 and they we add 9 to it because the sum of 6 and 3 is 9.

Finally, our answer we get is 17 so our X value is 2.
