Answer:

  1 (dollar per subscription)

Step-by-step explanation:

a) The term "rate of change" refers to "slope" or "unit rate" on a graph. In a linear equation, it is the coefficient of the variable.

On the graph, it can be found by counting the vertical units that correspond to each horizontal unit. On this graph, a horizontal increase of 1 grid square (5 subscriptions) causes an increase of 1 grid square ($5) in earnings. The rate of change is ...

  m = rise/run = $5/(5 subscriptions) = $1 per subscription

__

c) As indicated above, this will translate to the coefficient of the variable in the equation.

  E = n + 45

Answer:

$1.68

Step-by-step explanation:

The total cost is $16.07 and there was 2 things bought- the oranges and the juice bottles. to make it easier to find the cost of the juice bottles, we'll subtract the cost of the oranges (2.63) from the total (16.07), which gives us 13.44. this number represents the total cost of only the bottles. To find out the cost if each individual bottle, you need to divide the total (13.44) by the number of bottles (8). This gives us 1.68, so the cost of each bottel is $1.68

Answer:

R= 22537

Step-by-step explanation:

Given:

The expression is

[tex]\sqrt{180m^2}[/tex]

To find:

The value of the given expression by using the perfect squares.

Solution:

We have,

[tex]\sqrt{180m^2}[/tex]

It can be written as

[tex]=\sqrt{2\times 2\times 3\times 3\times 5\times m^2}[/tex]

[tex]=\sqrt{(2)^2(3)^25m^2}[/tex]

[tex]=\sqrt{(2\times 3\times m)^25}[/tex]

[tex]=\sqrt{(6m)^25}[/tex]

[tex]=6m\sqrt{5}[/tex]

Therefore, the value of given expression is [tex]6m\sqrt{5}[/tex].

Answer:

22.74 liters

Step-by-step explanation:

GIven data

Felix's washing machine uses 6 gallons of water

we are told that  A gallon is approximately 3.79 liters

Hence if  a gallon is approximately 3.79 liters

then 6 gallons of water will be x liters

cross multiply we have

x= 6*3.79

x= 22.74 liters

Hence 6 gallon will be 22.74 liters

Answer:

y = -6 + 2/3x can I get brainliest?

Step-by-step explanation:

Just add 2/3x to both sides

y-2/3x=-6

 +2/3.      +2/3

cannot combine like term with number so..

y = -6 + 2/3x

[tex]y= 1.25(2)^{x}[/tex]

Step-by-step explanation:

[tex]y= 1.25(2)^{x}[/tex]

For x=0

[tex]y= 1.25(2)^{0} = 1.25[/tex]

For x=1

[tex]y= 1.25(2)^{1} = 1.25(2)=2.5[/tex]

For x=2

[tex]y= 1.25(2)^{2} = 1.25(4)=5[/tex]

For x=3

[tex]y= 1.25(2)^{3} = 1.25(8)=10[/tex]

Answer:

$50.88

Step-by-step explanation:

Adjusted Price without tax = 0.8 * 60,

0.8 * 60 = 48,

With Tax = 1.06 * 48,

1.06 * 48 = 50.88

∴ New Price = 50.88

Answer:

Its $12.84

Step-by-step explanation:

20 percent of $60 is 12, and the sales tax is $.84, so you add those two together and you get $12.84! Hopes this helps and good luck!

Answer:

5x^3-9x^2-6x + 8

= (x+1)(5x-4)(x-2)

Step-by-step explanation:

Firstly, we need to get the other polynomial by which we can multiply the linear factor

What we have to do here is to divide the bigger polynomial by its linear factor

We can do this by long division, please check attachment for this

By kind division, the other factor is;

5x^2-14x + 8

So, we proceed to factorize this;

We have this as ;

5x^2-10x-4x+ 8

5x(x-2) -4(x-2)

= (5x-4)(x-2)

Answer:

what are the equations?

Step-by-step explanation:

Using it's formula, the distance between these two points is given by:

[tex]\sqrt{97}[/tex].

Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

For this problem, the points are:

(2,4) and (6,-5).

Hence the distance is given by:

[tex]D = \sqrt{(6 - 2)^2+(-5 - 4)^2} = \sqrt{97}[/tex]

Answer:

10 visits

Step-by-step explanation:

According to the scenario, calculation of the given data are as follows,

Rewards for signing up = 80 points

Reward per visit = 2.5 points

Total points needed = 105

Let, number of visits = x

So, we can calculate number of visits by using following formula,

80 + (2.5 × X) = 105

2.5X = 105 - 80

2.5X = 25

X = 25 ÷ 2.5

X = 10 visits.

Hence, Olivia needs to make 10 visits in order to earn a free movie ticket.

Based on these calculations, Erica would have a higher total amount of savings than Darrell at the end of one year.

Multiplication is an arithmetic operation used to find the product of two or more numbers. It is a way of adding a number to itself a certain number of times. For example, the product of 2 and 3 is 6, which is obtained by adding 2 to itself three times (2 + 2 + 2). Multiplication can be represented using the multiplication sign "×" or the dot symbol ".", and the result is called the product. The numbers being multiplied are called factors.

To compare the total amount of savings Erica and Darrell have at the end of one year, we need to calculate their savings at the end of the year based on their initial savings and monthly deposits. For Erica, the total amount of savings after one year can be calculated as follows:

Total savings for Erica = 200 + (75 x 12) = 200 + 900 = 1100 dollars

For Darrell, the total amount of savings after one year can be calculated as follows:

Total savings for Darrell = 350 + (50 x 12) = 350 + 600 = 950 dollars

Therefore, based on these calculations, Erica would have a higher total amount of savings than Darrell at the end of one year.
