If all the coordinates are placed in a graph, the line would be straight. This would mean it is linear.

The answer is b,d,c, because the increase in x is same and the increase in y is also same but in a the increase in x is exponential meaning it gets multiplied so that is not linear.

Write an equation that relates Jacob and his mother's current ages. Solve the system of equations.
What are their ages?

Answers

Answer:

Jacob is 4 years old and his mother is 40 years old.

Step-by-step explanation:

Part 1: The linear equations are  and

Part 2: Solving the equations, we have,  and

Part 3: Jacob is 4 years old and his mother is 40 years old.

Explanation:

Part 1: Let j represent Jacob's age, and let m represent his mother's age.

It is given that, "Jacob's mother is three more than nine times as old as Jacob". Writing it as linear equation, we have,

It is also given that, "In eleven years, his mother will be five more than three times his age". Writing it as linear equation, we have,

Simplifying this, we get,

Thus, the linear equation is

The linear equations are   and

Part 2: Solving the linear equation, we get,

Substituting  in

Simplifying, we get,

Hence,

Substituting  in

Solving the equations, we have,  and

Part 3: Since, j represents jacob and m represents the jacob's mother

Thus, Jacob is 4 years old and his mother is 40 years old.

Jacob - 4 years old
The Mother - 40 years old

Why are the divisibility rules for 2, 3, and 5 very useful for determining prime and composite numbers

1. They are the smallest odd numbers
2. They add up to 10
3. They are prime numbers with nice divisibility rules
4. They multiply to 30
5. They can be multiplied together to make every number

Answers

Answer:

option 3.

Step-by-step explanation:

alright, ima explain each option.

1. "smallest odd numbers" 2 is an even number. that's out of the playing field.

2. "add up to 10" sure, they do add up to 10, but finding prime and composite numbers are all about division and multiplication.

3. this is true. 2, 3, and 5 are all prime numbers, and they have the nice divisibility rules. [ for 2, it has to be even, for 5, it has to end in 0 or 5, and 3 has to have the sum of its digits being divisible by 3. ]

4. they do multiply to 30, but this does not help break the composite numbers down.

5. we cannot make every number with just these. we can not multiply any other whole number to get 7 for per example, because it's a prime number.

Answer:

The last answer or Distance a number is from zero i think i dont know

Step-by-step explanation:

Where do the slope and y-intercept show up in the tables and graphs?

Answers

Answer:

Solution: The general form of the line on a graph is y = mx+c,

where y is the coordinate of the point along the y-axis,

x is the coordinate of the point along the x-axis,

m is the slope of the line or arc tan of the angle the line makes with the x-axis, and

c is the intercept the line makes on the y-axis.

Suppose we want a line having a slope of 45º with the x-axis and passes through point P (4,6), the equation of the line is

y = mx + c

6 = tan 45 * 4 + c, or

6 = 4 + c, or

c = 6–4 = 2.

Gina wants to solve the following proportion.


a / 5/8 = 3/5 / 2/3


A. explain how to solve the problem.

B. solve the proportion. show your work.

Answers

Step-by-step explanation:

please don't understand the question. will be happy if you take a shot of it.

Thanks

a/5/8 = 3/5 / 2/3

We can take the reciprocal of the denominator, since the denominator itself is a fraction

The above equation can be rephrased as,
(a) / (5/8) = (3/5) / (2/3)

Taking reciprocal

8a / 5 = 3*3 / 5*2

8a / 5 = 9 / 5*2

a = 9 * 5 / 5*2*8

5’s get canceled, 2 and 8 gets multiplied in the denominator.

We will then be left with,

a = 9 / 16

How To Demonstrate Successful Leadership In The Workplace By Dionne Mahaffey, Founder of The Life Purpose Coaching Institute As with all skills, some of us are more adept at leadership than others. However, if you find yourself lacking in this area, keep in mind that your current struggles may be taking you down the pathway to eventual success. You can leverage the key fundamentals of successful leadership in order to impact your team and become the leader you desire to be. Successful leaders are effective communicators. In fact, communication will most likely be the major building block of your success in leadership. What makes a communicator effective, exactly? I have found the following guidelines to be helpful: Always consider all angles before crafting your message. Think about the "who," "what" and "how" of the situation. Keep the following questions in mind: What is the issue at hand? How can it be solved? Who am I asking to take action? What are the possible obstacles? What tools will I need to provide to make the process easier? Make sure your message is understood. Anyone can deliver a message, but not everyone confirms that the message is understood. Dont hesitate to repeat yourself to make a point. Always ask your team members if they have any questions or comments. Wait five-to-10 seconds before moving on in order to give your team time to process the information and formulate responses. Manage and prevent conflicts with consideration and purpose. Handle conflict between employees immediately. Otherwise, you risk the creation of a toxic environment where employees fail to see you as a capable leader. Stay a step ahead and strive to prevent conflict by observing your employees and learning their emotional triggers. For example, consider your employees working styles: some are very methodical, plugging along to the end. Others procrastinate and then rush to accomplish everything at the last minute. A way to avoid conflict is to pair employees with similar working styles. Give specific and appropriate praise for individual and team efforts. When you specifically state what you appreciate, your praise should translate as being authentic, not as an empty gesture. For example, The candid testimonials you gathered gave us valuable insight on the product that we wouldnt have had otherwise. This conveys exactly what impressed you, and offers the bonus of reinforcing desired behavior.Title of Text: How to Demonstrate Successful Leadership in the WorkplaceAuthor: Dionne Mahaffey ---------------Subject: Occasion: Audience: Purpose: Speaker: Tone: Find f(-3) if f(x) = x2 .Type a numerical answer in the space provided.
