Answer:

  (a), (b), (c) are non-proportional

  (d) is proportional

Step-by-step explanation:

An equation or graph with a non-zero y-intercept is non-proportional. That is true for (a), (b), (c).

The table of (d) is proportional, with a constant of proportionality of 6.5.

Comment on (c)

In a proportional relation, price would go up with quantity, not down. If the prices both end in 9, one cannot be double the other, as would be required for the price of a gallon to be proportional to the price of a half-gallon.

Step-by-step explanation:

The height of statue is 12.2 inches in Troy's drawing.

Step-by-step explanation:

Given,

Actual height of statue = 305 feet

Scale used by Troy;

25 feet = 1 inch

1 feet =

305 feet =

305 feet =

305 feet = 12.2 inches

The height of statue is 12.2 inches in Troy's drawing.

Answer:

12.2 inches

Step-by-step explanation:

The scale is 1 inch = 25 ft

305 ft * (1 inch)/(25 ft) = 305/25 inches = 12.2 inches

Answer: 12.2 inches

Answer:

2x + y = 15

Step-by-step explanation:

Total amount with Manuel = $15

Cost of apps = $2

Cost of song = $1

x = number of apps purchased

y = number of songs purchased

Cost of apps × number of apps purchased + Cost of song × number of songs purchased = Total amount with Manuel

2*x + 1*y = 15

2x + y = 15

The linear equation that represents the combination of apps and songs manuel can purchase is 2x + y = 15

Answer:

x = -2

Step-by-step explanation:

Simplifying

2x + -5x = 3x + 12

Combine like terms: 2x + -5x = -3x

-3x = 3x + 12

Reorder the terms:

-3x = 12 + 3x

Solving

-3x = 12 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

-3x + -3x = 12 + 3x + -3x

Combine like terms: -3x + -3x = -6x

-6x = 12 + 3x + -3x

Combine like terms: 3x + -3x = 0

-6x = 12 + 0

-6x = 12

Divide each side by '-6'.

x = -2

Simplifying

x = -2

Answer:

x = 22.75

Step-by-step explanation:

Step 1: 4x - 38 = 53 <----- Here is the original problem.

Step 2: 4x - 38 + 38 = 53 + 38 <----- Add 38 to both sides.

Step 3: 4x = 91 <----- Simplify

Step 4: [tex]\frac{4x}{4} =[/tex] [tex]\frac{91}{4}[/tex] <----- Subtract both sides by 4.

x = 22.75

Answer:

- high tide occurs at 12 noon and 12 midnight

- Low tide occurs at 6 a.m and 6 p.m

- maximum depth value = 20 ft

- Minimum depth value = 15 ft

Step-by-step explanation:

The depth is modelled as;

y = 20 + 5 cos (πt/6)

We are told that t = 0 represents 12:00 midnight.

This is high tide because at t = 0, the cos function will be at it's maximum value of 1 since cos 0 = 1.

Max depth value is;

y = 20 + 5(0)

y = 20 ft

Minimum depth value will be the low tide and it will be when the cos function is equal to -1.

Thus;

y = 20 + 5(-1)

y = 15 ft

Since t represents number of hours and since at 12 midnight, t = 0, thus; high tide will occur again at;

12 noon

Also, let's check for low tide.

Let's try t = 6 which means 6 a.m

Thus;

y = 20 + 5 cos (π(6)/6)

y = 20 + 5 cos π

Cos π has a value of -1

Thus;

y = 20 + 5(-1)

y = 20 - 5

y = 15 ft

Thus;

Low tide occurs at 6 a.m and 6 p.m

Answer:

4 games

Step-by-step explanation:

Let the number of games rented from both be represented by: g

For Games - R - Us

Games-R-Us offers a video game rental program with a monthly fee of $10 plus $2 per game rental.

$10 + $2 × g

= 10 + 2g

For Games2Go

Games2Go charges a $2 monthly fee plus $4 per game.

$2 + $4 × g

= 2 + 4g

Hence,

Games-R-Us = Games2Go

10 + 2g = 2 + 4g

Collect like terms

10 - 2 = 4g - 2g

8 = 2g

g = 8/2

g = 4 games

Therefore, number of games you would have to rent from each company to have your total cost be the same amount is 4 games

Answer:

Growth rate is -0.25

Growth factor is 0.75

Step-by-step explanation:

The general form of an exponential equation is;

y = a(1 + r)^x

Where a is the initial value

r is the growth rate

For x = 3; we have

168.75 = 400(1 + r)^3 •••• (i)

For x = 2, we have

225 = 400(1 + r)^2 •••••(ii)

Divide i by ii

That will be;

168.75/225 = 1 + r

1 + r = 0.75

r = 0.75-1

r = -0.25

The growth rate is -0.25

The growth factor is 1-0.25 = 0.75

Answer:

0.1125

Step-by-step explanation:

1.35 divided by 12 = 0.1125

Answer:

$0.11 per egg

Step-by-step explanation:

unit cost means how much each one costs

there are 12 eggs in a dozen

so all you have to do is divide $1.35 by 12

which equals $0.1125

but money is only counted by the hundredths place so we have to round

and that would be $0.11

Answer:

Step-by-step explanation:

(X,y) (x-6, y+4)

The transformation rule for the new  ΔR'S'T' is  (x, y) →  (x - 6, y + 4). The correct option is (c).

The graph of a function can be transformed by either shifting it in the right, left, up or down.

When the transformation is rightwards, the function becomes as f(x - a).

For left shifting it is f(x + a).

The given problem can be solved by using the rule of transformation as follows,

For the translation of 6 units left and 4 units up, it can be written as,

Suppose the coordinate of a vertex of ΔRST be given as (x, y).

Then, as per the rule the new coordinate of ΔR'S'T' is (x - 6, y + 4).

Hence, rule that best describes the transformation given in the problem is (x, y) →  (x - 6, y + 4).
