Answer: 24

Step-by-step explanation: The first side is 2 by 4 by 1 which equals 8. The middle is 2 by 2 by 2 which equals 8. The last side is 2 by 4 by 1 which equals 8. 8 plus 8 plus 8 equals 24.

Answer: f(x)=x-1

Step-by-step explanation: If you observe the points you will notice that each output is exactly one less than the input, x, so the function is f(x)=x-1.

Problem 2

Based on those variables, we can form these equations

The system of equations is

[tex]\begin{cases}x+y+z = 75\\x = 3y+6\\z = y-11\\\end{cases}[/tex]

Let's start with the first equation. Then apply substitution like so

x+y+z = 75  

3y+6+y+z = 75 ... plug in x = 3y+6

4y+6+z = 75

4y+6+y-11 = 75 ... plug in z = y-11

5y-5 = 75

5y = 75+5

5y = 80

y = 80/5

y = 16 = amount of candy Joe collected

z = y-11 = 16-11 = 5 = amount Josh collected

x = 3y+6 = 3*16+6 = 54 = amount Ian collected

======================================================

Problem 3

x = number of pounds of candy that sells for $1.49 a pound

1.49x = cost of buying those x pounds of candy at that unit price

4.50*5 = 22.50 = cost of buying 5 pounds at $4.50 per pound

1.49x+22.50 = total cost

x+5 = total weight in pounds

(total cost)/(total weight) = final cost per pound

(1.49x+22.50)/(x+5) = final cost per pound

(1.49x+22.50)/(x+5) = 3.64

1.49x+22.50 = 3.64(x+5)

1.49x+22.50 = 3.64x+18.20

22.50-18.20 = 3.64x-1.49x

4.30 = 2.15x

2.15x = 4.30

x = (4.30)/(2.15)

x = 2

======================================================

Problem 5

g = number of ghosts

w = number of witches

s = number of scarecrows

g+w+s = 22 = total number of items

w = g+1 since there's one more witch compared to ghosts

s = w-7 since there's 7 less scarecrows than witches

The system we need to solve is

[tex]\begin{cases}g+w+s = 22\\w = g+1\\s = w-7\\\end{cases}[/tex]

We'll use substitution here as well

g+w+s = 22

g+w+w-7 = 22 ... plug in s = w-7

g+2w-7 = 22

g+2(g+1)-7 = 22 ... plug in w = g+1

g+2g+2-7 = 22

3g-5 = 22

3g = 22+5

3g = 27

g = 27/3

g = 9, there are 9 ghosts

w = g+1 = 9+1 = 10 witches

s = w-7 = 10-7 = 3 scarecrows

10 witches and 3 scarecrows

The ODE

y''' - 7y'' + 8y' + 16y = 0

has characteristic equation

r ³ - 7r ² + 8r + 16 = 0

which can be factorized as

(r - 4)² (r + 1) = 0

Then the characteristic solution to the ODE is

y(x) = C₁ e ⁴ˣ + C₂ x e ⁴ˣ + C₃ e ⁻ˣ

Answer:

  29 square units

Step-by-step explanation:

One estimate could be obtained by approximating the shape by a polygon with vertices at ...

  (-3, 3), (2, 2), (2, -2), (-3, -4), (-4, -3), (-3, -1)

The idea is to try to have about as much area outside this boundary as inside with reference to the curve shown.

This can be subdivided into a trapezoid with the first four vertices shown, and a triangle with the last three vertices shown. The respective areas are ...

  trapezoid area = 1/2(b1 +b2)h = 1/2(7+4)(5) = 27.5

  triangle area = 1/2bh = 1/2(3)(1) = 1.5

Then the total estimated area is about 27.5 +1.5 = 29 square units.

Answer:

[tex]x2=\frac{y2-y1}{m} +x1[/tex]

Step-by-step explanation:

Step 1: Multiply both sides by (x2-x1)

m(x2-x1)=y2-y1

Step 2: Divide both sides by m

x2-x1=(y2-y1)/m

Step 3: Add x1 to both sides

[tex]x2=\frac{y2-y1}{m} +x1[/tex]

Answer:

270 is the answer if you add

Answer:

Step-by-step explanation:

P = 2L + 2W

L = 4w - 30

w = w

P = 2(4w - 30) + 2W

but  P = 240

2(4w - 30) + 2w = 240         Remove the brackets.

8w - 60 + 2w = 240             Combine

10w - 60 = 240                     Add 60

10w - 60 + 60 = 240+60      Combine

10w = 300                             Divide by 10

w = 30

L = 4w - 30

L = 4*30 - 30

L = 120 - 30

L = 90

Answer:

$650.  This was the original price.

Step-by-step explanation:

Let p represent the original price.

The following expression calculates the value of p:  (1 - 0.38)p = $403.  Note that '1' indicates full price and that '0.38' indicates a 38% discount.

(1 - 0.38)p = $403 simplifies to (0.62)p; = $403.

Dividing both sides by 0.62 yields $650.  This was the original price.

Answer:

$650

Step-by-step explanation:

Line up $ with $ and % with % then cross multiply

$403 represents ........100% full price -38% discounted  = 62%

$ x amount of the original price represents .........................100%

x*62 = 403*100, cross multiply

x = (403*100)/62, divide both sides by 62

x = $650

Answer:

There are 3 oatmeal cookies.

Step-by-step explanation:

===========================================================

Explanation:

Let's isolate the variable y in the first equation

-2x - y = 1

-2x = 1 + y

1+y = -2x

y = -2x-1

Then we'll plug this into the second equation

-4x - 2y = -1

-4x - 2(-2x-1) = -1

-4x + 4x + 2 = -1

0x + 2 = -1

0 + 2 = -1

2 = -1

We run into a contradiction. No matter what x value we pick, the last equation will never be true. This leads to a domino effect to cause the first set of original equations to never be true when considered as a system.

Therefore, this system is inconsistent. There are no solutions. These two lines graph out parallel lines that never intersect.

Answer:

360 people in 3 hours. 120 people per hour.

Step-by-step explanation:

How many times do 20 minutes go into 3 hours?

Well, 60 min. ÷ 20 min. = 3

So, 3 x 3 = 9

So 40 people went on the ride each 20 minutes. And there are (3) 20 minutes in every hour.

So 3 hours would be 9 x 40 = 360

120 people per hour because 40 x 3 = 120

and 20 minutes (3) times equals 1 hour.

Answer:

y = -4, x = 9

Step-by-step explanation:

If a line is horizontally passing through a point, then the equation of that line must be the y-value of that coordinate point. Likewise, if a line is passing vertically through a point, then the equation of that line must be the x-value of that coordinate point.

Apply the theory to this problem.

The equation for the horizontal line is y = -4

The equation for the vertical line is x = 9
