Answer:

x = 27.

Step-by-step explanation:

log9 x = 3/2

By the definition of a log:

9^3/2 = x

x =   (√(9)^3)

x = 3^3

x = 27.

Answer:

5 units

Step-by-step explanation:

Here, we want to find the distance CP

the distance from the center of the circle to the circumference is referred to as radius.

Hence CP is the radius of the circle

Also CN is another radius and also CK is another radius

Thus, mathematically; CN = CK

This means that;

x^2 -20 = 3x -10

x^2 -20 -3x + 10 = 0

x^2 -3x -10 = 0

x^2 -5x + 2x -10 = 0

x(x-5) + 2(x-5) = 0

(x-5)(x+2) = 0

x = 5 or -2

To get CP , we can substitute for x in any of the given expressions

Let’s use 3x-10

Using x = 5

3(5) -10 = 15-10 = 5

Using x = -2

3(-2) -10 = -6-10 = -16

But since length cannot be negative , 5 units is our answer

Answer:

z/5 = 6

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:

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:

W=4 l=16

Step-by-step explanation:

Let w = width

Let l = length

Since the length is 4 times the width, l=4w

Perimeter of rectangle = 2l + 2w

= 2(4w)+2w

=10w

The perimeter of the rectangle =40, so

40=10w and w=4

Plug w into the length equation : l=4w=4(4)=16

Answer: 15 pounds of apples left!

Step-by-step explanation:

Yellow: 9 times 2 = 18 apples

Red: 9

Green: 14

Add them all together- 18 plus 9 plus 14 =41.

Subtract 26 from 41 = 15

15 pounds of apples left!

The answer would be x=14.5

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

and then you have it

[tex]x=29[/tex]

Step-by-step explanation:

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.

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.

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.
