Answer:

Step-by-step explanation:

Parabola f(x) = ax² + bx + c passing through points (8,0) and (12,0) means that 8 and 12 are its root and (x-8) and (x-12) are its factors

So we get:

               f(x) = a(x - 8)(x - 12)

The parabola passes through point (13, -5) that means if x=13 then f(x)=-5

So:

      -5 = a(13 - 8)(13 - 12)  

      -5 = a(5)(1)

      -5 = 5a

       a = -1          {<0 so parabola opens down}

Therefore:

                 f(x) = -(x - 8)(x - 12)

And expanding:

                f(x) = -(x² - 12x - 8x + 96)

So the standard form equation of the parabola:

                f(x) =  -x² + 20x - 96

Answer:

314 million

Step-by-step explanation:

Given that :

Number of motor vehicle in the U.S for every 1000 people = 828

If the number of motor vehicle in the United States = 260 million

Then,

Let x = number of people Given number of vehicles = 260,000,000

1000 people = 828 vehicles

x = 260,000,000

828x = (260,000,000 * 1000)

828x = 260,000,000,000

x = 314009661. 835

x = 314 million (approx)

Answer:

Answer Choice D- y=x/5

Step-by-step explanation:

All the numbers in the table fit in and correlate to the equation. You can substitute any of the x's into the equation and get y correctly this is why the equation y=x/5 is the solution.

Answer:

3oz of pasta per serving

Step-by-step explanation:

Given parameters:

Number of oz of pastas used = 2oz

Quantity of serving  = [tex]\frac{2}{3}[/tex]

Unknown:

Number of oz of pasta per serving  = ?

Solution:

To solve this rate problem use;

  Number of oz of pasta per serving = [tex]\frac{number of oz of pasta}{number of serving}[/tex]  

 Number of oz of pasta per serving  = [tex]\frac{2}{\frac{2}{3} }[/tex]  = 2 x [tex]\frac{3}{2}[/tex]   = 3oz of pasta per serving

Answer:

The line of the equation is:

[tex]y-7=5\left(x+8\right)[/tex]

Step-by-step explanation:

Given

As the point-slope form is given by

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope

substituting the values m=5 and the point (-8, 7)

[tex]y-7=5\left(x-\left(-8\right)\right)[/tex]

[tex]\mathrm{Apply\:rule}\:-\left(-a\right)=a[/tex]

[tex]y-7=5\left(x+8\right)[/tex]

Therefore, the line of the equation is:

[tex]y-7=5\left(x+8\right)[/tex]

Answer:

  A = {put, the, cake, in, basket}

  B = {is, the, cake, in, basket}

  C = {no, the, cake, in, basket}

  D = { }

Step-by-step explanation:

A = (A -B) ∪ (A∩B) ∪ (A∩C}

A = {put} ∪ {the, cake, in, basket} ∪ {the, cake, in, basket}

A = {put, the, cake, in, basket}

__

B = (B -A) ∪ (B -C) ∪ (B∩A) ∪ (B∩C)

B = {is} ∪ {is} ∪ {the, cake, in, basket} ∪ {the, cake, in, basket}

B = {is, the, cake, in, basket}

__

C = (C -B) ∪ (C∩A) ∪ (C∩B)

C = {no} ∪ {the, cake, in, basket} ∪ {the, cake, in, basket}

C = {no, the, cake, in, basket}

Answer: 6 3/4

Step-by-step explanation:

You have to mulitply 2 x 4 + 1 = 9 and 4 is going to be the denomiator and how much can 3 can go into 9 only 3 times and that going to be on top of the denomiator  and 2 x 3 = 6

Answer:

acute

Step-by-step explanation:

Step-by-step explanation:

let eqn be y = mx + b.

m = (9 - 1)/(2 - 4) = -4

sub (4, 1):

1 = -4(4) + b

b = 17

therefore, it's y = -4x + 17
