What is the value of (23−19)×43−59?

Answer:

y = 0.47x + 25

y1 = 41.45 and not 55.55

Step-by-step explanation:

Given that:

x = number of brochures

y = total. Cost

Total cost of 35 brochures = $41.45

Total cost of 65 brochures = $55.55

The ordered pairs :

(x1, y1) ; (x2, y2)

x1 = 35 ; y1 = 41.45 ; x2 = 65 ; y2 = 55.55

(35, 41.45), (65, 55.55)

The slope :

Slope (m) = change in y / change in x

m = (y2 - y1) / (x2 - x1)

m = (55.55 - 41.45) / (65 - 35)

m = 14.1 / 30

m = 0.47

The y intercept :

y - y1 = m(x - x1)

y - 41.45 = 0.47(x - 35)

y - 41.45 = 0.47x - 16.45

y = 0.47x - 16.45 + 41.45

y = 0.47x + 25

Lila incorrectly chose 41. 45 as y1

Answer:

C. Lila made an error in Step 3 when she did not use the x- and y-coordinates from the same ordered pair.

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}

27×9+4

243+4

247

Answer:

247

Step-by-step explanation:

(20 + 7) x 9 + 4

(27) x 9 + 4

243 + 4 = 247

Thus, (20+7) x 9+4 = 247

Answer:

this answer should be green

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

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

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 slope is 23

Step-by-step explanation:

Answer:

8.73 Ounces

Step-by-step explanation:

8.73 + 8.86 = 17.59

17.59 - 0.23 = 17.36

17.36 divide by 4 = 8.73

Each bowl has 4.46 ounces of fruit.

The division is one of the four basic mathematical operations, the other three being addition, subtraction, and multiplication.

Now it is given that,

ounces of strawberries = 8.73 ounces

ounces of blueberries = 8.86 ounces

So, total ounces of fruits = 8.73 ounces + 8.86 ounces

⇒  total ounces of fruits = 17.59 ounces

Left over fruit = 0.23 ounces

So, total ounces of fruit in all bowls = 17.59 ounces - 0.23 ounces

⇒ total ounces of fruit in all bowls = 17.82 ounces

Since there are 4 bowls.

Thus, ounces of fruit in each bowl = 17.82/4 ounces

⇒ ounces of fruit in each bowl = 4.46 ounces

Thus, Each bowl has 4.46 ounces of fruit.

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]
