To describe a specific arithmetic sequence, Elijah wrote the recursive formula:

Write a linear equation that models this sequence using the sketchpad below.

Answer:

Step-by-step explanation:

x = number of cars

12x = 3.50x + 34

12x - 3.50x = 34

8.5x = 34

x = 34/8.5

x = 4 <=====he would have to sell 4 cars

In this case, Luke must sell [tex]\(\boxed{4}\)[/tex] cars for his revenue to equal his expenses.

To determine how many cars Luke must sell for his revenue to equal his expenses, let's define the variables and set up the equation.

Let x be the number of cars Luke sells.

Revenue:

Luke sells each car for $12, so his revenue for selling x cars is:

[tex]\[ \text{Revenue} = 12x \][/tex]

Expenses:

Luke's expenses include $3.50 per car and a fixed cost of $34 for tools. So his total expenses for x cars are:

[tex]\[ \text{Expenses} = 3.50x + 34 \][/tex]

We need to find the number of cars x such that his revenue equals his expenses:

12x = 3.50x + 34

To solve for x  subtract 3.50x  from both sides:

12x - 3.50x = 34

8.50x = 34

Now, divide both sides by 8.50:

[tex]\[ \text{Expenses} = 3.50x + 34 \][/tex]

x = 4

Therefore, Luke must sell [tex]\(\boxed{4}\)[/tex] cars for his revenue to equal his expenses.

Answer:

Step-by-step explanation:

Given that y varies inversely with x then the equation relating them is

y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation

(A)

To find k use the given condition y = 2 when x = 10

k = yx = 2 × 10 = 20, thus

y = [tex]\frac{20}{x}[/tex] ← equation of variation

(B)

When x = 4, then

y = [tex]\frac{20}{4}[/tex] = 5

One roll of plain costs $20 and one roll of shiny costs $20 also.

Step-by-step explanation:

Let,

Cost of one roll of plain = x

Cost of one roll of shiny = y

According to given statement;

2x+2y=80     Eqn 1

8x+10y=360    Eqn 2

Multiplying Eqn 1 by 4

[tex]4(2x+2y=80)\\8x+8y=320\ \ \ Eqn\ 3[/tex]

Subtracting Eqn 3 from Eqn 2

[tex](8x+10y)-(8x+8y)=360-320\\8x+10y-8x-8y=40\\2y=40[/tex]

Dividing both sides by 2

[tex]\frac{2y}{2}=\frac{40}{2}\\y=20[/tex]

Putting y=20 in Eqn 1

[tex]2x+2(20)=80\\2x+40=80\\2x=80-40\\2x=40[/tex]

Dividing both sides by 2

[tex]\frac{2x}{2}=\frac{40}{2}\\x=20[/tex]

One roll of plain costs $20 and one roll of shiny costs $20 also.

The equation which represents the amount of minutes.m that it will take to fill the pool is 200 = 60 + 10m

Which equation represents the amount of minutes ( m) that it will take to fill the pool?

Let

m = amount of minutes that it will take to fill the pool

Gallons of water in the pool = 60 gallons

Capacity of the pool = 200 gallons

Additional gallons added per minutes = 50 gallons / 5

= 10 gallons per minutes

The equation:

200 = 60 + 10m

200 - 60 = 10m

140 = 10m

Divide both sides by 10

m = 140/10

m = 14 minutes

Therefore, it takes Anita 14 minutes to fill the pool.

1000 is divisible by 4, 600 is divisible by four, and 44 is divisible by for: add up you get 250+150+11

Step-by-step explanation:

411

Using place value, the quotient of 1,644 and 4 is: 411.

Given the dividend, 1,644, to divide it by the divisor, 4, break down 1,644 using place value, and divide by 4 separately.

1,644/4 = (1,000 ÷ 4) + (600 ÷ 4) + (44 ÷ 4)

1,644/4 = (250) + (150) + (11)

1,644/4 = 411

Therefore, using place value, the quotient of 1,644 and 4 is: 411.

The approximate length of the radius is 3 feet

Step-by-step explanation:

Given:

circumference of a circle = 18.41 feet

To Find:

approximate length of the radius = ?

Solution:

Let the radius of the circle be r

We know that the circumference of the circle C is given by the formula

C =[tex]2 \pi R[/tex]

Substituting the values, we get

18.41 =[tex]2\times \pi \times R[/tex]

The initial fee of a train ticket, given a constant fee per stop, can be calculated by finding the constant fee per stop and subtracting the total of this fee for a given number of stops from the total price for those stops. By this calculation, the initial fee is $2.50.

To determine the initial fee that is related to the price of a train ticket, which consists of an initial fee plus a constant fee per stop, we should first calculate the cost per stop. We can do this by subtracting the price of a ticket for 3 stops from the price of a ticket for 7 stops. So, we get $12.50 - $6.50 = $6.00. We find the difference in the number of stops, which is 7 - 3 = 4 stops. Divide the total price difference by the difference in the number of stops to get the constant fee per each stop: $6.00 / 4 stops = $1.50 per stop. Now we know the constant fee for each stop, so we subtract that from the total price for 3 stops to find the initial fee: $6.50 - ($1.50 * 3) = $2.50. So, the initial fee is $2.50.

To find the initial fee, we need to determine the additional cost per stop. We can do this by using the formula y = mx + b, where y represents the price of the ticket, x represents the number of stops, m represents the constant fee per stop, and b represents the initial fee.

Using the given data, we can set up two equations using the points (3, 6.50) and (7, 12.50).

By subtracting these two equations, we can determine the value of b, which represents the initial fee. Thus, the initial fee is $3.

Answer:

The graph of y = f(x) will shift left 6 units, as shown in figure a.

Step-by-step explanation:

A translation means we are able to move the graph of a function up or down - normally called Vertical Translation -  and right or left - commonly called Horizontal Translation.

If we replace the graph of y = f(x) with the graph of y = f(x + 6). It means we have added 6 units to the input, meaning the graph y = f(x) will shift left by 6 units as 6 is being added directly to the  x, so it is f(x + 6).

For example, if y = x² is the original function and of 6 is directly added to x i.e. f(x + 6), making it y = (x + 6)². So, we can easily observe that there will be a horizontal translation left of 8 units, as shown in figure a.

So, the graph of y = f(x) will shift left 6 units.

The graph of y = f(x) will shift left 6 units. The correct option is the third one.

For any function y = f(x), we define an horizontal translation of N units as:

y = f(x + N)

Where if:

N > 0, the translation is to the left.

N < 0, the translation is to the right.

Here we have:

y = f(x + 6)

So this is a translation of 6 units to the left.

The given expression at p = 5 can be written as:

[tex]4(p^4)  > 2p -3[/tex]

Step-by-step explanation:

Here, the given expressions are:

Now, substitute the value of p = 5 in both the given expressions, we get:

[tex]4(p^4)  = 4(5^4)  = 4 (625)   =  2,500\\\implies 4(p^4) = 2,500[/tex]

Similarly,

[tex](2p-3)  = 2(5) - 3 = 10 -3 = 7\\\implies 2p - 3  = 7[/tex]

So,now comparing  both the values at p = 5, we get:

To compare the two plans and find the amount of driving for which they cost the same, we can set up an equation and solve for x. The two plans cost the same for 450 miles of driving.

To compare the two plans and find the amount of driving for which they cost the same, we need to set up an equation. Let's assume the amount of driving is represented by the variable x. The total cost for Plan 1 can be calculated as:

Total cost = $46 + $0.13x

The total cost for Plan 2 can be calculated as:

Total cost = $55 + $0.11x

We can set the two equations equal to each other and solve for x:

$46 + $0.13x = $55 + $0.11x

$0.02x = $9

x = $9 / $0.02 = 450

Therefore, the two plans cost the same for 450 miles of driving.
