Solve the equation.
1-3x + 1 + 10x = y + 4

Answer:

x = 1

Step-by-step explanation:

ln x + ln x = 0

2ln x = 0

ln x = 0

recall ln x = [tex]log_{e}[/tex]x

so equation becomes

[tex]log_{e}[/tex]x = 0

or [tex]e^{0}[/tex]=x

since anything raised to the power of zero = 1

x = 1

Answer:

x = 1

Step-by-step explanation:

We are to find the solution of the following logarithmic equation:

[tex] ln ( x ) + l n ( x ) = 0 [/tex]

We will add the similar elements to get:

[tex] 2 l n ( x ) = 0 [/tex]

Dividing both sides by 2 and simplify to get:

[tex] \frac { 2 l n ( x ) } { 2 } = \frac { 0 } { 2 } [/tex]

[tex]ln(x)=0[/tex]

Applying the rule [tex]a=log_b(b^a)[/tex] to get:

[tex]0=ln(e^0)=ln(1)[/tex]

[tex]ln(x)=ln(1)[/tex]

Here the logs have the same base, so:

x = 1

Answer:

22.34 km²

Step-by-step explanation:

Here we have a circle whose diameter is 5  1/3 km.  As an improper fraction, that's 16/3 km.  Half that, or 8/3 km, is the radius.

The area of a circle is A = πr², where r is the radius.

In this case, the area is A = π(8/3 km)², or (64/9)π km², or 22.34 km² (same as first answer choice).

Answer:

7 7/12

Step-by-step explanation:

Find the amount of rolls in all that were donated:

60 x 12 = 720.

The total amount used is 679. Subtract 679 from 720:

720 - 629 = 91.

Find the amount per dozen. Divide 91 with 12:

91/12 = 7 7/12

7 7/12 is your answer.

~

The local Youth Baseball League used 56 dozen rolls with 7 extra rolls for a total of 679 hot dogs, which is expressed as 56 7/12 dozen.

The local Youth Baseball League served a total of 679 hot dogs using rolls from the grocery store.

If a dozen represents 12 items, we need to calculate how many dozens of rolls were used in this circumstance.

Since 679 hot dogs were served and each dozen contains 12 rolls, we can divide 679 by 12 to find the number of dozens.

Dividing 679 by 12, we get:

679 ÷ 12 = 56 dozens with a remainder of 7.

Therefore, 56 dozen rolls were fully used, with an additional 7 rolls from another dozen.

To express this in mixed number form, it would be 56 7⁄12 dozen rolls.

Answer:

C. 11

Step-by-step explanation:

Evaluate 2(x + 1) - 3 when x = 6.

2(x + 1) - 3 <== substitute 6 for x

2(6 + 1) - 3 <== distribute 2

2(6) + 2(1) - 3

12 + 2 - 3 <== add and subtract

14 - 3

11 <== answer

Hope this helps!

Hey there!

2(x + 1) - 3

= 2(6 + 1) - 3

= 2(7) - 3

= 14 - 3

= 11

OR

2(x + 1) - 3

= 2(6 + 1) - 3

= 2(6) + 2(1) - 3

= 12 + 2 - 3

= 14 - 3

= 11

Therefore, your answer is: 11

Answer:

Rebecca has 18 nickels and 27 dimes

Step-by-step explanation:

Let x be the number of nickels Rebecca has, then 45-x is the number of dimes she has.

The total value of Rebecca's coins is $3.60.

1 nickel - 5 cents

x nickels - 5x cents

1 dime - 10 cents

45-x dimes - 10(45-x) cents

Total x nickels and 45-x dimes is 5x+10(45-x) cents that is $3.60=360 cents. So,

5x+10(45-x)=360

5x+450-10x=360

5x-10x=360-450

-5x=-90

5x=90

x=18

45-x=45-18=27

The base of the exponential expression 4^5 is 4.

The base of an exponential expression refers to the number being raised to a power.

option C.

The statement that best describes a square is: A special rectangle that has four sides of equal length. This statement aligns with the definition of a square within the field of geometry, where a square is understood as a type of rectangle with all sides being the same length. Therefore, the correct answer is C. A special rectangle that has four sides of equal length.

A square indeed has four right angles, similar to a rectangle. By extension, it has congruent opposite sides and equal angles, but the defining feature that differentiates a square from other rectangles is the fact that all four sides are of equal length. The concept of rectangles forming squares can be seen in the given reference, implying that equal rectangles can be arranged to form a square - a concept important in understanding how a square is a special case of a rectangle.

Answer:

Step-by-step explanation:

There is a standard cost just for renting the car.

Let the daily cost = x

Let the addon be = z The add on is the amount they charge just to give you the keys and do the paper work. It might include insurance.

y = z + 4x

y = 180

z = ??

x = 4

y = 325

z = ??

x = 9

Equation 1: 180 = z + 4x

Equation 2:325 = z + 9x

Subtract (1) from (2)

325 = z + 9x

180 = z + 4x                         Subract

145 = 5x                               Divide by 5

145/5 = 5x/5

x = 29

What you have found is the daily cost. Now you have to find the fixed cost.

y = 29x + z

180 = 29*4 + z

180 = 116 + z                  Subtract 116 from both sides

180 - 116 = z

z = 64

Answer: Part A

y = 29x + 64

Part B

f(x) = 29x + 64

Answer: $22.50

Step-by-step explanation: let x represent the amount Laura and Lilly contributed each. If Laura and Lilly contributed the same amount, x+x=2x=45. If 2x=45, divide both sides by 2 to find the value of x. 45/2= 22.5.

Laura contributed $15 toward the purchase of the video game.

The question is asking to determine the amount contributed by Laura to buy a video game for their brother, Liam, if the entire cost of the game is $45 and Laura contributed half as much as Lilly. For simplicity, let's assume Lilly contributed x dollars. Then Laura, contributing half as much, would have contributed x/2 dollars. Given that their total contribution is $45, we set up the equation x + x/2 = 45. Solving for x, we find that Lilly contributed $30 and Laura, half of this, contributed $15.

To find the product of two expressions, we use the distributive property and multiply each term from the first expression with each term from the second expression, then combine the like terms.

The product of[tex](3a + 2)(4a^2 - 2a + 9) is 12a^3 - 6a^2 + 23a + 18.[/tex]

To find the product of two binomials, you can use the distributive property. In this case, you multiply each term in the first binomial, 3a and 2, by each term in the second binomial, 4a^2, -2a, and 9, and then combine like terms.

[tex](3a + 2)(4a^2 - 2a + 9) = 3a * 4a^2 + 3a * (-2a) + 3a * 9 + 2 * 4a^2 + 2 * (-2a) + 2 * 9[/tex]

Now, perform the multiplications:

[tex]12a^3 - 6a^2 + 27a + 8a^2 - 4a + 18[/tex]

Combine like terms:

[tex](12a^3 - 6a^2) + (27a - 4a) + 1812a^3 - 6a^2 + 23a + 18[/tex]

Answer:

(b) 240

Step-by-step explanation:

First, we use the Pythagorean formula using the given side lengths to find x. Then we use x to find the side lengths. Then we add the side lengths to find the perimeter.

Pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

We see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. The only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

Replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240

Answer:

( 212 - 0 )/ ( 100 - 32 ) = 212 / 68 = 3.11 ;

Step-by-step explanation:

Let m = slope

m = (delta y)/(delta x)

m = (212 - 32)/(0 - 100)

m = 180/(-100)

m = -180/100

You can reduce -180/100 to the lowest term. I'll let you do that.

Step-by-step explanation:

we know that

The scale factor of the dilation is 0.25 ----> given problem

The coordinates of point A(-5,-3) and F(3,1)

step 1

Find the x-coordinate of point A'

The horizontal distance between A and F is equal to

AFx=3-(-5)=8

The horizontal distance after dilation between A'F is equal to

A'F=0.25*8=2

so

the x-coordinate of vertex A' is equal to the x-coordinate of F minus the horizontal distance after dilation A'F

A'x=3-2=1

step 2

Find the y-coordinate of point A'

The vertical distance between A and F is equal to

AFy=1-(-3)=4

The vertical distance after dilation between A'F is equal to

A'Fy=0.25*4=1

so

the y-coordinate of vertex A' is equal to the y-coordinate of F minus the vertical distance after dilation A'F

A'y=1-1=0

therefore

The coordinates of vertex A of the image is (1.0)

[tex]Volume\ ratio=(\frac{1\ cm}{3\ cm})^3\\\\Volume\ ratio=\frac{1}{27}[/tex]

Knowing that the volume of the larger cylinder is 2,106 cubic centimeters, you need to multiply it by the volume ratio to find the volume of the smaller cylinder.

Therefore:

[tex]V_{smaller}=\frac{1}{27}(2,106\ cm^3)\\\\V_{smaller}=78\ cm^3[/tex]

Hello There!

Your answer is the last option r*n^2

I plugged in the values for each of these dilations.

Answer:

(x - 8)^2 + (y - 4)^2 = 16.

Step-by-step explanation:

The standard form can be written as:

(x - a)^2 + (y - b)^2 = r^2 where (a, b) is the center and r = the radius.

So here we have a = 8, b = 4 and r = 4.

(x - 8)^2 + (y - 4)^2 = 4^2

(x - 8)^2 + (y - 4)^2 = 16.
