Answer:
Step-by-step explanation:Physical changes only affect the physical properties, such as color, texture, and shape, of a substance. When a substance is changed physically, its chemical properties remain the same. On the other hand, a chemical change alters the chemical properties of a substance.During a physical change the elements and compounds stay as they are.While Chemical changes make new substances.

This is a simple graph, but I want to know if I’m right. If the line goes through the origin does that automatically mean it’s positive?
And when it doesn’t go through the origin does that mean it’s automatically negative?
THANK YOU.!
Answer: This is a negative graph and it is proportional because it goes through the origin.
Step-by-step explanation:
Just beacause it goes through the origin does not mean it will be positive nor negative, if the line goes from the top left of the grid slanted down, it is negative. If the line goes from the top right of the graph slanted down, it is positive. It is proportional because it is a straight line that goes through the origin.
Answer:Under↓↓↓
Step-by-step explanation:
Ok so in this case it's a negative slope, because the line is going from left to right.
If the line was going form right to left then It would be a positive slope.

A. They both have a positive correlation, but Graph 1 has a stronger association. B. They both have a positive correlation, but Graph 2 has a stronger association. C. They both have a strong association, but Graph 1 has a positive correlation while Graph 2 has a negative correlation
d. They both have a strong assoication, but Graph 1 has a negative correlation while Graph 2 has a positive correlation
The comparison between the two graphs is that: B. they both have a positive correlation, but Graph 2 has a stronger association.
What is a positive correlation?A positive correlation refers to a terminology that describes a scenario in which two or more variables move in the same direction and are in direct proportion.
This ultimately implies that, a positive correlation exists in a graph when its variables have a linear relationship or are in direct proportion.
Based on the graphs attached in the image below, we can deduce that the two graphs both have a positive correlation, but Graph 2 has a stronger association.

For what value of b, would the equation 3/4(12x−9)+b/4=5−3(2−3x) have infinitely many solutions?
b = ____
When the value of b is 23 then the equation 3/4(12x−9)+b/4=5−3(2−3x) have infinitely many solutions.
When does a system of linear equation have no solution?When both the lines(represented by both the equations) are parallel and not coincident, then that system of linear equations have no solutions as there is no common point on both line.
If they are coincident, then there will have infinite solution since in that case, they will have infinite points in common.
Thus, if two lines are not in any of above case, they intersect at single point and in that case, the considered system of equation has unique single solution.
The equation 3/4(12x−9)+b/4=5−3(2−3x) have infinitely many solutions.
When b = 23 ,
3/4(12x−9)+b/4=5−3(2−3x)
When the value of b is 23 then the equation 3/4(12x−9)+b/4=5−3(2−3x) have infinitely many solutions.

Explain how to compare two fractions that have the same numerator and different denominators. Use an example to help justify your response.
Answer in paragraph form using complete sentences and include any calculations, graphs, and labeled diagrams as appropriate..
Answer:
Step-by-step explanation:
2 fractions with the numerator and different denominators can be compared when you find the lowest common denominators (LCD. For example 1/2 and 1/3 have the same numerator, but the denominators are not so you have to find the LCD. The LCD, in this case, is 6, so the fractions would be 3/6 and 2/6 and now if you compare you can tell that 3/6 is greater than 2/6 so 1/2 is greater than 1/3.
Answer:
Answer is down below :D
Step-by-step explanation:
A numertator is the top number and the denominators are the bottom number of a fraction. You can tell the difference because if you look at the top number of one fraction and you look at the other that you're supposed to compare and there the same number, then they are the same. For example, 1/2 and 1/3 have the same numetators but not denominators. Now for denominators you have to look at the bottom number but if the two fractions you're comparing have the same bottom number then there the same, but if they have two different bottom numbers, then they are not the same. For example again: 1/3 and 1/9 The may seem the same but there not since the bottom number is different.
