The equation that represents the relationship between Anne's age and Betty's age is a = 2b - 3. The equation indicates that Anne's age is 3 years less than twice Betty's age.

The relationship between Anne's age and Betty's age is expressed through the given information: 'Anne is 3 years younger than twice Betty's age'. This can be translated into an equation using 'a' to represent Anne's age and 'b' to represent Betty's age. Accordingly, the equation becomes a = 2b - 3.

The equation shows that to get Anne's age, you have to double the age of Betty and then subtract 3 years. For example, if Betty was 10 years old, Anne would be 2*10 - 3 = 17 years old.

The common difference (or common ratio) = 0.75

Step-by-step explanation:

i) let the first term be [tex]a_{1}[/tex] = 80

ii) let the second term be [tex]a_{2}[/tex]  = [tex]a_{1}[/tex] . r = 80 × r = 60      ∴  r = [tex]\frac{60}{80}[/tex] = 0.75

iii) let the third term be     [tex]a_{3}[/tex]  = [tex]a_{2}[/tex] . r = 60 × r = 45      ∴  r = [tex]\frac{45}{60}[/tex] = 0.75

iv) let the fourth term be   [tex]a_{4}[/tex] = [tex]a_{3}[/tex] . r = 45 × r = 33.75   ∴ r = [tex]\frac{33.75}{45}[/tex] = 0.75

Therefore we can see that the series of numbers are part of a geometric progression and the first term is 80 and the common ratio = 0.75.

Answer:

He needs to pay back $64

Step-by-step explanation:

He has already paid $4802, and according to the chart that goes with this question, he owed $4866.

What he owes: $4866

subtract what he has paid: $4802

4866-4802=64

So he needs to pay the IRS $64

You can use subtraction here to get to the correct option.

The correct option for the given condition is

Option A: He will pay $64

Since the chart that goes along with the given question says that  Yung had to give $4866 for the taxes, and since it is given that Yung already paid $4802, we see that he didn't paid full tax yet since 4802 < 4866.

So he has to pay the remaining amount of the tax.

To get the remaining amount he has to pay, we will use subtraction.

Thus:

Remaining amount = Total amount to pay - amount already paid

Remaining amount = $4866 - $4802 = $64

Thus,

The correct option for the given condition is

Option A: He will pay $64

Answer:

x = 2, y = -1

Step-by-step explanation:

2x + 3y = 1.....(1)

5x + 2y = 8.....(2)

multiply equation (1) by 5 and equation (2) by 2

10x + 15y = 5 .......(3)

10x + 4y = 16......(4)

solving by elimination method

we subtract equation (4) from (3)

hence ...

11y = -11

dividing both sides by 11

y = -1

substituting y = -1 in equation (1) to solve for the value of x

2x + 3(-1) = 1

2x - 3 = 1

rearranging,

2x = 3 + 1

2x = 4

dividing both sides by 2

A tree diagram is a form of graphical representation that visually displays possible outcomes of an experiment or event. It is particularly useful in solving complex probability problems. An example would be if you were to draw balls from an urn multiple times and wanted to visualize all the possible outcomes.

A tree diagram is a graphical representation used to determine the outcomes of an experiment. It consists of multiple branches, typically representing different possible outcomes or choices.

As an example, let's consider an urn with 11 balls: 3 red and 8 blue. If you were to draw two balls, one at a time, with replacement (putting the first ball back before the second draw), a tree diagram would show all possible outcomes. Your first set of branches would represent the color of the first ball drawn (red or blue) and from each of those branches, a second set would signify the color of the second ball drawn.

So branch one could show red for the first draw, and from that branch you would have two further branches, red and blue, showing the possibilities for the second draw. The same would be done for the first draw being blue. This tree diagram illustrates the different scenarios of this experiment.

[tex]New\ level\ of\ cholesterol = 192[/tex]

Step-by-step explanation:

Given:

Reduced level of cholesterol = 20%

Original level of cholesterol = 240

We need to find cholesterol level now

Solution:

First we find reduced level of cholesterol using percentage formula.

[tex]Percentage = \frac{Value}{Toatl\ value}\times 100[/tex]

Substitute all known value in above formula.

[tex]20 = \frac{Value}{240}\times 100[/tex]

[tex]Value = \frac{20\times 240}{100}[/tex]

[tex]Value = \frac{4800}{100}[/tex]

[tex]value = 48[/tex]

So reduced level of cholesterol = 48

But we need to find cholesterol level now, so we subtract reduced level from original level of cholesterol.

[tex]New\ level = original\ level - reduced\ level[/tex]

[tex]New\ level = 240 -48[/tex]

[tex]New\ level = 192[/tex]

The coordinates of a point on the directed segment from (3,-2) to (8,0) that divides it into a ratio of 3:1 is (6.75, -0.5). The correct option is A.

A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.

Let the line be represented as AB, therefore, the coordinates of points A and B are (3,-2) and (8,0), respectively. The coordinate of the point m that divides the line AB in a ratio of 3:1 is,

x = [(x₂×m)+(x₁×n)]/(m+n)

x = [(8×3)+(3×1)]/(3+1)

  = (24+3)/4

  = 6.75

y = [(y₂×m)+(y₁×n)]/(m+n)

y = [(0×3)+(-2×1)]/(3+1)

Final answer:

The coordinates of the point that divides the directed segment from (3,-2) to (8,0) in the ratio of 3:1 are a) (6.75, -0.5), using the section formula.

Explanation:

When finding the coordinates of a point on a directed segment that divides it into a specific ratio, such as 3:1, the formula for the section formula in coordinate geometry is used. This formula allows us to calculate the coordinates of the point that divides the segment internally or externally in a given ratio (m:n) using the coordinates of the endpoints (x1,y1) and (x2,y2). The formula for the point (x, y) that divides the segment internally in the ratio m:n is:

x = (mx2 + nx1) / (m + n)

y = (my2 + ny1) / (m + n)

For the directed segment from (3, -2) to (8, 0) and a ratio of 3:1, we find the point by this method:

x = (3×8 + 1×3) / (3 + 1) = (24 + 3) / 4 = 27 / 4 = 6.75

y = (3×0 + 1×(-2)) / (3 + 1) = (0 - 2) / 4 = -2 / 4 = -0.5

Thus, the coordinates of the point that divides the segment in the ratio 3:1 are a) (6.75, -0.5).

Answer:Briana needs 562likes to reach 2000

Step-by-step explanation:

The number of likes Briana has = 1438

The number of likes Briana wants to reach = 2000

The remaining of likes she needs= 2000-1438 = 562

Hence, Briana needs 562 more likes to reach 2000likes on her picture

Final answer:

Briana needs 562 more likes to reach 2,000 likes on her dog's picture, calculated by subtracting her current likes from the target amount.

Explanation:

Briana currently has 1,438 likes on a picture of her dog dressed as a superhero. To determine how many more likes Briana needs to reach 2,000 likes, we perform a simple subtraction operation:

2,000 (desired amount of likes) - 1,438 (current amount of likes) = 562 more likes needed.

Therefore, Briana needs 562 additional likes to reach her goal of 2,000 likes on the picture of her dog.

The inverse of the function f(x) = 3x^8 + 1 is found by reversing the operations: subtract 1, divide by 3, and take the eighth root. The correct equation for the inverse is f⁻¹(x) = ⁸√((x - 1) / 3), which simplifies to f⁻¹(x) = ((x - 1) / 3)^(1/8). The options provided do not match this result.

Explanation:

The question asks for the equation of the inverse of the given function f(x) = 3x^8 + 1. To find the inverse function, f⁻¹(x), we must reverse the operations of the original function on x. First, you would subtract 1 from both sides to undo the addition, and then divide by 3 to undo the multiplication, followed by taking the eighth root to reverse the exponentiation. The correct inverse function will therefore reverse all these operations in that order.

Here's the step-by-step solution:

Start with y = 3x^8 + 1

Subtract 1 from both sides: y - 1 = 3x^8

Divide both sides by 3: (y - 1) / 3 = x^8

Take the eighth root of both sides: x = ⁸√((y - 1) / 3)

Therefore, the inverse function is f⁻¹(x) = ⁸√((x - 1) / 3), which simplifies to f⁻¹(x) = ((x - 1) / 3)^(1/8). However, none of the options provided fully match this result, implying there might be a typo or mistake in the question or options provided.

To find the number of robberies this year, we need to calculate 14% of last year's total and subtract it from that total. This results in an estimated 286 robberies this year.

The question asks for the number of robberies this year given a 14% decrease from the prior year's total of 332 robberies. To calculate this, you would multiply last year's number of robberies by 14% (or 0.14) to find the decrease in robberies. Then, subtract this decrease from the original number of robberies.

First, calculate the decrease: 332 * 0.14 = 46.48. This rounds down to 46 robberies, as it would be unlikely to have a fraction of a robbery.

Next, subtract this from the original amount: 332 - 46 = 286. There were approximately 286 robberies this year, rounded to the nearest whole number, assuming a 14% decrease from 332.

The amount in a savings account increased from ​$150 to ​$156. The percent of​ increase is equal to 4%.

The percentage simply means out of 100. It means proportionating a value out of another value to be out of 100. Percentage facilitates comparison since the base of all values becomes equal.

To find the increase in value, we first need to calculate the increase in numbers i.e., new value minus the original value. Divide it by the original value and multiply by 100, and you get the required result.

Original amount in savings account = $150

increased amount in savings account = $156

Increase in amount  = $156 - $150 = $6
