Answer:

Step-by-step explanation:

5(x - 3) ? x + 13

if x = 6

5(6 - 3) ? 6 + 13

15 ? 19

15 ≠ 19

Step-by-step explanation:

When substituting 6 for x, the equation becomes:

5(6 - 3) ?= 6 + 13

Now, we can solve both sides of the equation:

5(3) ?= 6 + 13

15 ?= 19

Since these are not equal, the equation is not true for x = 6.

A description that best compare the graph of the functions is: B. the line for function A is steeper.

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation:

y - y₁ = m(x - x₁)

Where:

First of all, we would find the slope of function B;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (-1 + 2)/(3 - 0)

Slope (m) B = 1/3.

At data point (0, -1) and a slope of 1/3, function B can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y + 1 = 1/3(x - 0)

y = 1/3(x) - 1

In conclusion, the line for function A is steeper because it has a greater slope than function B i.e 3 > 1/3.

The inverse of function f(x) when f(x) = -2 is f¯¹(x) = 2x + 3.So, the correct option is D.

To find the inverse of a function, we switch the x and y variables and solve for y. So, if f(x) = -2, we have:
x = -2
y = f(x) = -2
Switching x and y, we get:
x = f¯¹(y)
y = -2
Solving for f¯¹(y), we get:
f¯¹(y) = 2y + 3
Therefore, the inverse of f(x) when f(x) = -2 is f¯¹(x) = 2x + 3.
To find the inverse of a function, we need to swap the input (x) and output (f(x)), and then solve for the new input. Given f(x) = -2, let's find the inverse:
1. Swap the input and output: x = -2
2. Solve for the new input: Since the function f(x) is a constant function and doesn't involve x, the inverse of f(x) when f(x) = -2 is f¯¹(x) = 2x + 3.
Therefore, Option D is the correct inverse of f(x).

The probability of flipping heads twice followed by tails three times is 1/32 or approximately 0.031.

Each coin flip is an independent event, meaning the outcome of one flip does not affect the outcome of any other flip. Therefore, the probability of getting heads on any one flip is always 1/2, regardless of previous outcomes.

Using this information, we can calculate the probability of flipping heads twice followed by tails three times as:

P(heads) = 1/2

P(tails) = 1/2

P(heads on first flip) = 1/2

P(heads on second flip) = 1/2

P(tails on third flip) = 1/2

P(tails on fourth flip) = 1/2

P(tails on fifth flip) = 1/2

P(heads twice followed by tails three times)

= P(heads on first flip) x P(heads on second flip) x P(tails on third flip) x P(tails on fourth flip) x P(tails on fifth flip)

= (1/2) x (1/2) x (1/2) x (1/2) x (1/2)

= 1/32

Therefore, the probability of flipping heads twice followed by tails three times is 1/32 or approximately 0.031.

The point at coordinate 3 represents the weighted average.

Point E measures (-1) and has weight 2x weight of F

point F has a measure of 2 and no particular stated weight

point G measures 6 and has a weight of 3x weight of F

Since we can assign a weight to point F and the other weights will be based on that, let's just keep it simple and give point F a weight of 1.

That gives E a weight of 2, and G a weight of 3.

So, E value times E weight is   (-1)   x   2 = -2

F value times F weight is      2   x   1 =   2

G value times G weight is   6   x   3 = 18

Sum of (value x weight)  =  18

Sum of the weights = 2 + 1 + 3 = 6

we get the weighted average by taking the sum of (value x weight) products (18) and then dividing by the sum of the weights (6).

18/6 = 3, the weighted average

Hence, the point at coordinate 3 represents the weighted average.

A triangle is a two-dimensional geometric shape that is defined by three straight sides and three angles. It is the simplest polygon with three sides and three vertices.

We know that the magnitude x is gotten from;

x² - 11x + 146 + 39 - 3x +44 = 180 (Sum of angles in a triangle)

x²- 11x - 3x + 146 + 39  +44 = 180

x²- 14x + 229= 180

The answer to all parts is shown below.

1. The diameter of a donut is 3 inches.

so the circumference is πd = 3π ≈ 9.42 inches.

2. 2.5 square feet is equal to 2.5 x 144 = 360 square inches.

3. The minimum length, width, and height of the box are equal to the diameter and height of the donut, which is 3 inches and 1.5 inches, respectively.

Adding 1/2 inch to each dimension gives a length of 4 inches, a width of 4 inches, and a height of 2 inches.

4. The area of the bottom of the new box is length x width

= 4 x 4 = 16 square inches.

The length and width of the new box meet Dave's requirements because they are each greater than or equal to the minimum length and width of 3.5 inches (3 inches + 1/2 inch).

5. The surface area of the new box can be calculated as follows:

Top and bottom: 2 x (length x width) = 2 x (4 x 4) = 32 square inches

Front and back: 2 x (height x length) = 2 x (2 x 4) = 16 square inches

Sides: 2 x (height x width) = 2 x (2 x 4) = 16 square inches

Total surface area = 32 + 16 + 16 = 64 square inches.

6. The surface area of one original box is equal to the sum of the areas of the top, bottom, and four sides.

Each side has dimensions of 3 inches by 1.5 inches,

so the area of each side is 3 x 1.5 = 4.5 square inches.

The area of the top and bottom is 3 x 3 = 9 square inches.

Therefore, the surface area of one original box is:

Top and bottom: 2 x 9 = 18 square inches

Sides: 4 x 4.5 = 18 square inches

Total surface area = 18 + 18 = 36 square inches.

The surface area of the new box is 64 square inches, so the total cardboard needed for one box is:

64 square inches / 144 square inches per square foot = 0.44 square feet

The cost of cardboard for one box is:

0.44 square feet x $0.20 per square foot = $0.088

To find the cost of 35 new boxes, we multiply the cost per box by the number of boxes:

35 boxes x $0.088 per box = $3.08

Therefore, the new box costs less than the original box, which costs $21.00 for 35 boxes.

The information given in the table to  produce a direct equation that relates the number of Calories burned to the time spent jogging. Let's use the  pitch- intercept form y =  mx b, where y represents the number of Calories burned( in hundreds), x represents the time spent jogging( in  twinkles), m represents the rate of Calories burned( in hundreds per  nanosecond), and b represents the  original Calories burned( in hundreds).  To find m, we can use the points( 10, 13) and( 15, 19), which represent two ordered  dyads on the line. We can find the  pitch of the line using the  pitch formula  

m = ( y2- y1)/( x2- x1)  m = ( 19- 13)/( 15- 10)  

m = 1.2  So the equation for the line is  y = 1.2 x b.

 To find b, we can use the point

( 10, 13)  = 1.2( 10) b  b = 0.7

 So the complete equation for the line is  y = 1.2 x0.7  Now we can use this equation to  break for x, the number of  twinkles Lance needs to jog to burn 380 Calories.  

380 = 1.2 x0.7  = 1.2 x  x = 316.08

B) frequency of the pitch that is 73 notes up the keyboard is 1760 cycles per second.

A. To find how many notes up the piano keyboard the pitch with a frequency of 440 cycles per second is, solve the formula

n = 1 + 12 × log₂(f/27.5) for n,

where f = frequency of the pitch to find and n = number of notes up the keyboard.

Substituting f = 440:

n = 1 + 12 × log_2(440/27.5)

n = 1 + 12 × log_2(16)

n = 1 + 12 × 4

n = 49

Therefore, the A above middle C with a frequency of 440 cycles per second is 49 notes up the piano keyboard.

B. Using the same formula, n = 1 + 12 × log₂(f/27.5), to find the frequency of the pitch that is 73 notes up the keyboard. Solving for f:

73 = 1 + 12 × log₂(f/27.5)

72 = 12 × log₂(f/27.5)

6 = log₂(f/27.5)

2⁶ = f/27.5

Answer:

C. y = 1/3x + 4

Step-by-step explanation:

To find the equation of the line that passes through the given points, we can use the slope-intercept form of the equation of a line, which is:

y = mx + b

where m is the slope of the line and b is the y-intercept.

To find the slope of the line, we can use the formula:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) and (x2, y2) are any two points on the line. We can choose the points (x1,y1) = (-3,3) and (x2,y2) = (6,6) from the table.

m = (6 - 3) / (6 - (-3)) = 3/9 = 1/3

Now that we have the slope, we can use the point-slope form of the equation of a line to find the y-intercept:

y - y1 = m(x - x1)

where (x1,y1) is any point on the line. We can choose the point (x1,y1) = (3,5) from the table.

y - 5 = (1/3)(x - 3)

Now we can solve for y to get the equation in slope-intercept form:

y = (1/3)x + (5 - 1/3*3)

y = (1/3)x + 4

Therefore, the equation of the line that passes through the given points is C) y= 1/3x + 4.
