Answer:

end point of a segment  X₂ = - 8 ;  Y₂ = 21

Step-by-step explanation:

given;

midpoint = ( Mx = -4 , My = 13 )

endpoint ₁  = ( X₁ = 0 ,  Y₁ = 5 )

find the other endpoint ₂ ( X₂ , Y₂)

use the mid point formula to get the other endpoint:

Mx = ( X₁ + X₂ ) / 2              My = ( Y₁ + Y₂ ) / 2

- 4 = (0 + X₂) / 2                 13 = (5 + Y₂) / 2

-8 = 0 + X₂                         26 = 5 + Y₂

X₂ = -8                                    Y₂ = 21

Answer:

Quedan 3 libras de azúcar en el costal.

Step-by-step explanation:

Una kilo es aproximadamente dos libras y dos libras y media equivalen a un paquete, para determinar la cantidad remanente de libras de azúcar luego de las ventas se calcula la masa vendida por regla de tres compuesta:

[tex]x = 5\,p \times \frac{2,5\,kg}{1\,p}\times \frac{2\,lb}{1\,kg}[/tex]

[tex]x = 25\,lb[/tex]

Juana vendió 25 libras de azúcar. Entonces, la masa remanente de azúcar en el costal es:

[tex]x = 28\,lb-25\,lb[/tex]

[tex]x = 3\,lb[/tex]

Quedan 3 libras de azúcar en el costal.

The total amount of sugar left in the sack is 3 pounds.

Using the conversion:

1 kg = 2lb

2.5kg =5lb

Amount of sugar left in the sack = Total  - amount sold

Amount of sugar left in the sack = 28lb - 25lb

Amount of sugar left in the sack = 3lb

Answer:

H = 3t + 8

Step-by-step explanation:

Since the plant has an initial height of 8 inches, this will be added to the amount it grows each month.

3t will represent how much it grows t months after he bought the plant, since it grows 3 inches each month.

So, the equation will be H = 3t + 8

Answer:

a) Equation of the tangent of the parabola

12 x - y -16=0

b)

slope of the tangent  at x=2.1

[tex](\frac{dy}{dx}) = 3(2.1)^{2} = 13.23[/tex]

slope of the tangent  at x=2.01

[tex](\frac{dy}{dx}) = 3(2.01)^{2} = 12.1203[/tex]

Step-by-step explanation:

Step(i):-

Given parabola  y = x³  ....(i)

Differentiating equation (i) with respective to 'x'

  [tex]\frac{dy}{dx} = 3x^{2}[/tex]

slope of the tangent

[tex](\frac{dy}{dx})_{(2,8)} = 3x^{2} = 3(2)^{2} =12[/tex]

Step(ii):-

Equation of the tangent of the parabola

[tex]y-y_{1} = m (x-x_{1} )[/tex]

y-8 = 12 (x -2)

12 x - 24 -y +8 =0

12 x - y -16=0

b)

slope of the tangent  at x=2.1

[tex](\frac{dy}{dx}) = 3(2.1)^{2} = 13.23[/tex]

slope of the tangent  at x=2.01

[tex](\frac{dy}{dx}) = 3(2.01)^{2} = 12.1203[/tex]

Answer:

41/120, 7/20, 43/120, 11/30, 3/8

Step-by-step explanation:

Write the numbers.

1/3 & 2/5

We need a common denominator, but not the least common denominator. Both 3 and 5 are factors of 60, so let's use 60 as the common denominator.

Multiply 1/3 by 20/20:

1/3 = 20/60

Multiply 2/5 by 12/12:

2/5 = 24/60

Let's multiply each fraction again, but this time by 2/2.

1/3 = 40/120

2/5 = 48/120

Now it's easy to find 5 numbers between 40 and 48, so we get:

41/120, 42/120, 43/120, 44/120, 45/120

Some of these fractions can be reduced, so our answer is:

41/120, 7/20, 43/120, 11/30, 3/8

Question #2 Answer: 76

Calculate 4 to the power of 3 and get 64.

64−(−3)381​+9≈76

Calculate −3 to the power of 3 and get −27.

64−−2781​+9=76

Divide 81 by −27 to get −3.

64−(−3)+9=76

The opposite of −3 is 3.

64+3+9=76

Add 64 and 3 to get 67.

67+9=76

Add 67 and 9 to get 76.

76

Question #3 Answer: -4

Calculate 2 to the power of 4 and get 16.

16−324​−12=−4

Divide 24 by 3 to get 8.

16−8−12=−4

Subtract 8 from 16 to get 8.

8−12=−4

Subtract 12 from 8 to get −4.

2(x-(3/2))^2+(20-9)/2=0

2(x-(3/2))^2+11/2=0

2(x-(3/2))^2=-11/2

Explanation:

Going from figure (1) to figure (2) has us rotate 90 degrees counterclockwise. Note the smallest side of the green figure how it is horizontal, and it corresponds to the smallest side of the blue figure and it is vertical. The center of rotation is the top right corner of the green figure.

Then we apply a translation to go from figure (2) to figure (3). This is another way of saying we shifted the figure some distance left/right and up/down. In this case, we shifted 1 unit to the right and 4 units down.

Answer: m(x) = -7x

Step-by-step explanation:

egen2020

The which function has an inverse that is a function is m(x) = -7x

let f be a Function. If any horizontal line intersects the graph of f extra than once, then f does now not have an inverse. If no horizontal line intersects the graph of f greater than once, then f does have an inverse. The belongings of getting an inverse may be very vital in arithmetic, and it has a call.

Answer:Dilation and rotation

Step-by-step explanation:

Answer:

See attached graph.

Step-by-step explanation:

This equation is already in slope-intercept form.

This means the term next to the x is the slope, and the constant being added is the y-intercept.

We know that the y-intercept will be 4 because that’s the constant being added. We also know the slope is [tex]\frac{2}{3}[/tex].

A slope of [tex]\frac{2}{3}[/tex] will increase in x by 3, for every increase in y by 2.

Answer:

[tex]x=2y+6[/tex]

Step-by-step explanation:

So we have the system:

[tex]-x+2y=-6\\3x+y=8[/tex]

If we isolate the x-variable in the first equation:

[tex]-x+2y=-6[/tex]

Subtract 2y from both sides:

[tex]-x=-6-2y[/tex]

Divide both sides by -1:

[tex]x=2y+6[/tex]

Therefore, we would substitute the above into the second equation:

[tex]3x+y=8\\3(2y+6)+y=8[/tex]

The answer is 2y+6

Further notes:

To solve for the system, distribute:

[tex]6y+18+y=8[/tex]

Simplify:

[tex]7y+18=8[/tex]

Subtract:

[tex]7y=-10[/tex]

Divide:

[tex]y=-10/7\approx-1.4286[/tex]

Now, substitute this value back into the isolated equation:

[tex]x=2(-10/7)+6\\x=-20/7+42/7\\x=22/7\approx3.1429[/tex]

Step-by-step explanation:

Start by solving the equation for x (☓)

[tex] - x + 2y = 6 \\ \: \: \: \: \: 3 + y = 8[/tex]

[tex]x = 6 + 2y[/tex]

[tex]3(6 + 2y) + y = 8[/tex]

[tex]y = - \frac{10}{7} [/tex]

[tex]x = 6 + 2 \times ( - \frac{10}{7} )[/tex]

[tex]x = \frac{22}{7} [/tex]

[tex] (\frac{22}{7} . - \frac{10}{7} )[/tex]

[tex](x.y) \: \: ( \frac{22}{7} . - \frac{10}{7} )[/tex]
