The signed number representation for David losing 15 dollars is -15, indicating a decrease of 15 units in his pocket.
We can use a negative value since he lost money to represent the change of David losing 15 dollars from his pocket using signed numbers. Using a signed number system, we represent positive values as regular numbers and negative values with a minus sign (-) in front of the number. So, in this case, the change can be represented as: -15
The negative sign (-) indicates that David lost 15 dollars. In signed number notation, the minus sign represents a decrease or a loss, while a positive sign (+) represents an increase or a gain.
In summary, the signed number representation for David losing 15 dollars is -15, indicating a decrease of 15 units in his pocket.

To solve this, all you need to do is divide 13 by 2 and two thirds. Let's do it:
[tex]13 \div 2\frac{2}{3}\\= 13 \div \frac{8}{3}\\= 13 \times \frac{3}{8}\\= \frac{13 \times 3}{8}\\= \frac{39}{8}\\= 4\frac{7}{8}[/tex]

Answer:
1. last choice
2. first choice
Step-by-step explanation:
First ImageThe reason why it is the last choice because when times keep going as distance also keeps increasing as well. But the last choice says that run at the end of track then turn around and run back. That means there must be a decreasing distance and a maximum value as well.
Therefore the only with max point/vertex is the absolute value which matches the last choice.
Second ImageFirst choice because the car straight forwards without any change. The car runs with a steady speed but the distance will keep changing without any change of distance.
So the answer is first choice.

The scatter plot shows the height x (in inches) and the weight y (in pounds) of 10 people. Find the weight of the person who is 63 inches tall. Then find the height of the person who weighs 135 pounds.
PLEASE HELP QUICK!!!!
Given:
Scatter plot shows the height x (in inches) and the weight y (in pounds) of 10 people.
To find:
The weight of the person who is 63 inches tall. Then find the height of the person who weighs 135 pounds.
Solution:
In the given scatter plot,
x = height (in inches)
y = weight (in pounds)
First we need to find the weight of the person who is 63 inches tall.
If height of a person is 63 inches, then x = 63.
From the given graph, it is clear that y = 110 at x = 63.
Therefore, the weight of the person who is 63 inches tall is 110 pounds.
Now, we need to find the height of the person who weighs 135 pounds.
If weight of a person is 135 pounds, then y = 135.
From the given graph, it is clear that x = 66 at y = 135.
Therefore, the height of the person who weighs 135 pounds is 66 inches.

ITS 1.2 JUST MAKE A GRIS IN YOUR NOTE BOOK
Step-by-step explanation:
1. Compare the strengths and weaknesses of the horizontal and vertical methods for adding and subtracting polynomials. Include common errors to watch out for when using each of these methods.
2. Explain why you cannot use algebra tiles to model the multiplication of a linear polynomial by a quadratic polynomial. As an added challenge, develop a model similar to algebra tiles that will allow you to show this multiplication. Describe an example of your model for the product (x + 1)(x2 + 2x + 2). 3. Imagine that you are teaching a new student how to multiply polynomials. Explain how multiplying polynomials is similar to multiplying integers. Then describe the key differences between the two. 4. If you multiply a binomial by a binomial, how many terms are in the product (before combining like terms)? What about multiplying a monomial by a trinomial? Two trinomials? Write a statement about how many terms you will get when you multiply a polynomial with m terms by a polynomial with n terms. Give an explanation to support your statement.
1.Each method works differently the angles inside them is what matters.
2. Manipulating algebra tiles can help people solve linear equations
3.Distribute each term of the first polynomial to every term of the second polynomial. Remember that when you multiply two terms together you must multiply the coefficient (numbers) and add the exponents. But with Integers you multiply two integers with different signs
4.So you know how
A monomial is a number, a variable or a product of a number and a variable.
multiply each term in one polynomial by each term in the other polynomial

Jermaine and Josh observed an anthill for their science project. They observed that an ant moved 45.0 millimeters (mm) in 85.0 seconds (s). How fast was the ant moving?
Answer:
Velocity =displacement/time
Distance covered is 45mm which is 0.045m or 0.45cm but the displacement is very small so use mm instead. Time taken (t) to cover the distance is 85s. V=45/85
V=0.53mm/s

If the simple interest on $6,000 for 3 years is $1,620, then what is the interest rate?
Answer:
Interest rate: 9%
Step-by-step explanation:
Using the simple interest formula: A=P(1+rt)
A=Final amount
P=Principal amount
r=rate
t=time (years)
We just need to put in the information we have from the question and solve for r.
7,620=6000(1+r3)
7,620/6000=1+r3
1.27=1+r3
0.27=r3
r=0.09
r=9%
