An equation which models the relationship between X and Y is

y = 54.5x

The correct answer is option (D) y = 54.5x

"A mathematical statement which contains an equal symbol between two algebraic expressions that have the same value."

From given data we can observe that,

163.5/3 = 54.5                           ...................(1)

327/6 = 54.5                              ...................(2)

599.5/11 = 54.5                          ...................(3)

From (1), (2) and (3),

y/x = 54.5

⇒ y = (54.5)x

Therefore, an equation which models the relationship between X and Y is y = 54.5x

The correct answer is option (D).

Step-by-step explanation:

Answer:

Price of each ticket = $70

The revenue generated from sales of 10 tickets = 70 x 10 = $700

After selling the 10 tickets, organization was still at loss of $800. This means total product cost of tickets = $800 + $700 = $ 1500

Net Profit = Revenue - Cost

Revenue from n tickets will be = 70n

Cost = $1500

So, net profit as a function of number of tickets sold = P(n) = 70n - 1500

Step-by-step explanation: Part 1) The units rates are

A)

B)

C)

D)

Part 2) The best buy is the size 48 1/4 we know that To find out the unit rate divide the total cost by the total volume

Part 1) Calculate the unit rate for each size

case A) we have 8 1/2 ounce bottle costs $0.99 Convert mixed number to an improper fraction

Find the unit rate

case B) we have

18 2/2 oz. bottle costs $1.49

Convert mixed number

Find the unit rate

case C) we have

48 1/4 oz. carton costs $2.49

Convert mixed number to an improper fraction

Find the unit rate

case D) we have

64 3/4 oz. carton costs $3.75

Convert mixed number to an improper fraction

Find the unit rate

Part 2) which size is the best buy

we know that

The best buy is the one with the smallest unit rate

so

The best buy is the size 48 1/4 oz

This is what the equation looks like: [tex]\frac{-3}{2}x - 9 = -27[/tex]

First, we transpose the terms to the other side. So after transposing [tex]-9[/tex], you get: [tex]\frac{-3}{2}x = -27 + 9[/tex]

Add them and you get: [tex]\frac{-3}{2}x = -18[/tex]

Next we transpose the coefficient of [tex]x[/tex] which is [tex]\frac{-3}{2}[/tex] to the other side, and while doing so the operation changes to a division. When dividing rational numbers, you take the reciprocal so you get: [tex]x = -18 * \frac{-2}{3}[/tex]

Multiply them and you get: [tex]x = 12[/tex]

Therefore, Option D is the correct answer :D

Answer:

Phreatophytes, like the mesquite tree, have adapted to desert conditions by developing extremely long root systems to draw water from deep underground near the water table.

Step-by-step explanation:

The mesquite's roots are considered the longest of any desert plant and have been recorded as long as 80 feet.

Answer:

Long roots for desert plants look similar to other roots, only more lengthy. The roots spread out from the base of the plant deep into the earth. Typically, the roots are larger than regular thread roots so that they absorb more water.

Answer:

D (0, -2), (1, 0), (3, 3), (4, -5)

Step-by-step explanation:

The first number in a coordinate pair (x, y) is the x, so the first number is how much left or right you go, where the second number is how far up or down you go. if the (x) is negative, you go left, if it's positive you go right, of the (y) is negative you go down, if it's positive you go up.

Answer:

Step-by-step explanation:

we have that

5x – 3y – x + 6z

5x – x – 3y + 6z------> this step is correct

5 + 3yz------> is not correct

because

1) 5x-x=5---> is not correct

the correct is

5x-x=4x

2) -3y+6z=3yz-----> is not correct

the correct is

-3y+6z=3*(2z-y)

therefore ,

the correct solution is

4x+3*(2z-y)
