Answer:

D) $9.06

correct on edge :)

The total amount of money saved from purchasing the plants at a marked down price is  $9.06

The first step is to determine the original price of one potted begonias: $6.57 / (1 - 0.27)  = $9

The first step is to determine the original price of one tomato seedling: $2.60 / ( 1 - 0.35)  = $4

The amount saved on potted begonias = ($9 - 6.57) x 2 = $4.86

The amount saved on tomato seedlings = (4 - 2.60) x 3 = $4.20

Total amount = $9.06

Answer:

  see the attachments for the graph(s)

Step-by-step explanation:

1) The point at (3, 6) is on the vertical line that is halfway between the zeros at x=-3 and x=9, so it represents the vertex of the function. That knowledge, with any of the other points, lets you write the vertex form of the equation.

  y = a(x -3)^2 +6

Using the point (0, 4.5), we can find the value of 'a':

  4.5 = a(0 -3)^2 +6

  -1.5 = 9a

  -1.5/9 = a = -1/6

So, the vertex form of the equation is ...

  y = -1/6(x -3)^2 +6

A graph of this is shown in the attachment.

__

2) Now that we know the leading coefficient is -1/6, we can write the equation in "intercept form" (factored form) as ...

  y = -1/6(x +3)(x -9)

In this form, each zero (p) gives rise to a factor (x-p).

The second attachment shows the graph of this.

__

3) We can also write the equation in standard form, by expanding the one in (2) above:

  y = -1/6(x^2 -6x -27)

  y = -1/6x^2 +x +9/2

The third attachment shows the graph of this.

Answer:

You have the number of nickels and the number of quarters both expressed in terms of the number of dimes.  So let your variable be the number of dimes.  Call this D.  Then the number of nickels is 4D, and the number of quarters is D+6.  The total value is

0.10(D) + 0.05(4D) + 0.25(D+6) = 4.25

Solve this for D, and use D to find 4D and D+6.

Answer:

5F + -9  C= 160       39°F = 3.9

Step-by-step explanation:

A Table showing Freezing Temperatures in degrees with 2 columns and 6 rows. The First row, F, has the entries, negative 13, negative 4, 5, 14, 23. The second column, C, has the entries, negative 25, negative 20, negative 15, negative 10, negative 5.

The table shows temperatures below freezing measured in different units. Complete the equation in standard form to represent the relationship between F, a temperature measured in degrees Fahrenheit, and C, a temperature measured in degrees Celsius.

5F + -9 C = 160

39°F = 3.9°C rounded to the nearest tenth of a degree

The co-relationship between temperatures measured in Fahrenheit F, and in Celsius C is shown using an equation.

What is an equation?

The equation is an expression that highlights the co-relationship between two or more variables.

Let F represent temperature measured in degrees Fahrenheit, and C, a temperature measured in degrees Celsius.

At 0°C, the temperature is 32°F. Also at 100°C, the temperature is 212°F, hence:

C = (5/9)(F - 32)

First, calculating the slope (m) :

From the table we have:

m = (C₂-C₁)/(F₂-F₁)

m = (-20-(-25))/(-4-(-13))

m = 5/9

The equation is now calculated :

C = m(F-F₁) + C₁

C = 5/9 (F + 13) - 25

5F = 9C + 160

For value of C for F= 39 , we have,

C = 5/9 (F + 13) - 25

C = 5/9 (39+13) - 25

C = 3.9

Therefore, the value of C is 3.9.

In the case when the point (x, y) is in Quadrant II so here considered that

your 'x' is negative and your 'y' is positive.

The second quadrant should be occur in the upper left-hand corner of the plane. X contains the negative values in this quadrant and y should have the positive values.

So based on the above information, we can say that your 'x' is negative and your 'y' is positive.

Answer:

29 questions on his test

Step-by-step explanation:

set it up as fractions equal to each other so that you can solve for x

 [tex]76\%= \frac{76}{100}[/tex]

x is the total number of questions on the test

we know that samuel got 22 of those questions correct, and a grade is calculated by dividing the number of correct answers by the total number of questions, so we can write

[tex]\frac{76}{100}=\frac{22}{x}[/tex]

then you can solve by cross multiplying

[tex]76x = 22 (100)[/tex]

[tex]76x=2200[/tex]

get the x by itself by dividing both sides by 76, and then you have x

[tex]\frac{76x}{76}=\frac{2200}{76}[/tex]

[tex]x=\frac{2200}{76}=28.947[/tex]

since you're not going to have .947 of a question, round it up to 29

Answer:

-57

Step-by-step explanation:

B- brackets

O- of

M- multiplication

A- addition

S - subtraction

-3[1+2(4+5)]

first solve what is in the brackets

(4+5) = 9

place 9 in the brackets

-3[1+2(9)]

now multiply the 2 and 9

2*9 = 18

-3[1+18)]

1+ 18 = 19

now multiply the (-3) with 19

= -57

Answer:

-57

Step-by-step explanation:

To solve this problem, you need to use the acronym PEMDAS.

P = parenthesis (if there is any in the expression) or brackets

E = exponents (if there is any in the expression)

D/M = Divide or Multiply or both

A/S = Add or Subtract or both

In the problem, you need to simplify the parentheses ( ) inside the brackets first. For example: -3 [1 + 2(4 + 5)]. That will equal to -3 [1 + 2(9)]. Next, you can solve the brackets now. Since there is both a addition and multiplication problem inside these brackets, you must do the multiplying first. For example,

-3 [1 + 2(9)]. That equals to -3 [ 1 + 18}. Next, do the addition inside of the brackets and then multiply that answer to -3. For example, -3 [1 + 18}. That equals to -3 [19]. Do the multiplication by a calculator or by hand. if you are doing by hand, ignore the signs of the numbers until the very end.

If doing by hand, first you need to multiply 9 by the 3 to get 27. Keep the 7 and borrow a 2 on top of the ones places which is 1. Multiply the 1 by the 3 which gets 3 and add 2 to the 3 to get 5. You got the 2 from multiplying 9 by 3 which is 27. Since the 3 in this problem is negative, that will leave your answer with a negative number. Since a negative times a postive will always be negative. If the number of negatives is odd in the problem, then it will a negative answer. If the number of negatives is even, the answer will be positive. Same thing applies to division. You get -57 as your answer.
