Step-by-step explanation:

Use A Geometric Model To Factor X2 - 9 By Following These Steps: Step 1: Model X2 - 9 By Placing Tiles
Answer 2

The equation x^2 - 9 is modeled by placing tiles. The image is attached below.

What is tile modeling?

It is the kind of modeling in which tiles are used to represent products. It provides a visual representation of the multiplication.

How can we make a model of multiplication?

To make a model, first, we must factorize the expression.

The given expression is x^2 - 9.

This can be factored as shown below:

x^2 - 9 = (x - 3)(x + 3)

We must now make a horizontal row containing x, -1, -1, and -1.

Similarly, we must make a vertical column containing x, 1, 1, and 1.

Now we must multiply each row and columnn to together and add them together as shown below:

x^2 - x - x - x + x + x + x - 9 = x^2 -9

This is the same as the given expression.

Thus, we have modeled the given expression by placing tiles in the product section.

Which system is most easily solved by elimination and why?

a. 3m - 4n = 1; 3m - 2n = -1

b. y = 4x - 2; y - 3x = 0

c. y = x; y = -x

Answers

Answer:

System A should be solved by elimination because you can easily cancel out the 3m to solve.

System B should be solved by substitution.  Since the an equation for the y value is given, you can easily substitute it into the other equation.

System C should be solved by graphing.  You don't have to worry about any slopes or intercepts to graph.  You can graph it using only whole numbers.

If the ordered a pair (6,2) is the solution to the system, what does that mean?

Answers

It means that the point (6,2) is on both graphs at the same time. In short, it is the intersection point of the two graphs.

Algebraically, the ordered pair (x,y) = (6,2) makes all of the equations in the system to be true equations. A true equation is one where it simplifies to have the same number on both sides.

A system with at least one solution is considered a consistent system. If there is only one solution, then the system is also considered independent.

Cheryl wants to find the number of hours seventh-graders do homework each week. There are 297 boys and girls in seventh grade. If Cheryl randomly surveyed 50 girls in the entire school to find the number of hours seventh-graders do homework each week, describe why she would get a biased sample



Please help ASAP

Answers

Note that Cheryl wants to find the number of hours seventh grade boys and girls spend on homework each week.

There are multiple causes of a biased sample.  Two of the most obvious ones I find are:

1.  She's surveying girls, but she is trying to get data on the number of hours all seventh graders (boys and girls) spend.

2. She's surveying 50 girls from the entire school, although she is trying to get data on seventh graders only.

Please help me asap help. The other two options are 6 2/8 and 6 1/4

Answers

Answer:

6 1/2

Step-by-step explanation:

To double the recipe we would need to multiply all the ingredients by 2. But since it is asking about the peaches, we only need to multiply 3 1/4 by 2. First we make the 3 1/4 to an improper fraction. (multiply denom. by the 3 then add the numerator. then keep the same denominator). The improper fraction of 3 1/4 would be 13/4. Now we can multiply by 2. That would give us 26/4 which reduces to 13/2. To change this back to a mixed number, we divide 13 by 2. That would give us 6 with a remainer of 1. So our answer is 6 1/2.

Which inequality best represents that ice cream at −3°C is cooler than ice cream at 1°C? (4 points)

a
−3°C > 1°C
b
−3°C 3°C
d
1°C < −3°C

Answers

Answer:

-3° C < 1°C is the correct option.

Step-by-step explanation:

As we know that:

The inequality symbol '<' means 'less than'.The inequality symbol '>' means 'more than'.

If someone says that something is cooler than the other thing, it indicates that it is lesser than the other based on its temperature.

As the ice cream at −3°C is cooler than ice cream at 1°C, it indicates that temperature -3° C < temperature  1°C.

Therefore, -3° C < 1°C is the correct option.

c.There is a positive relationship between calories and sodium. The relationship is strong.
d.As the number of calories increases, the amount of sodium decreases. The relationship is strong.

Answers

Answer:

answer C

There is a positive relationship between calories and sodium. The relationship is strong.

Step-by-step explanation:

The following is a correct interpretation of this value is option c. There is a positive relationship between calories and sodium. The relationship is strong.

The Correct interpretation of the value:

Since

A nutritionist collects data from 25 popular breakfast cereals.

The value of r for the resulting scatterplot is 0.83.

So based on this, we can say that there should be the positive relationship between calories and sodium.

And, due to this, the relationship is considered to be strong.

Answers

Answer: x = 61 and y = 29

Step-by-step explanation: In this problem, notice that we

have a transversal that intersects two coplanar lines at different points.

Let's start by finding the value of y.

In the diagram, 2y and 58 are corresponding angles and if two

parallel lines are cut by a trans. corr. <'s must be congruent.

So we can setup the equation 2y = 58.

Solving from here, we find that y = 29.

Now, notice that 58 and 2x form a straight angle or a linear pair.

When two angles form a straight angle, they are supplementary.

So we can setup the equation 2x + 58 = 180.

Solving from here, we find that x = 61.
