Answer:

Sample Answer: When a linear function is expressed in different forms, its slope and y-intercept remain the same. The slope from the equation is -1, and the y-intercept from the equation is 3. The slope from the table is -1, and the y-intercept from the table is −3. These are not the same functions.

Step-by-step explanation:

Answer:

The slope formula is y2 - y1/x2 - x1.  

Step-by-step explanation:

First plug in x = 1, x = 2, and x = 3 in to the equation y = 4x to find the first 3 points(Like the first three are shown for the table.) which are (1, 4), (2, 8), and (3, 12).  

The slope of the table would be 9 - 3/3 - 1, after subtracting you get 6/2. You would then divide 6 by 2, which gives you 3. 3 is the slope of the table.

The slope of the equation goes through the same process. 12 - 4/3 - 1, after subtracting it's 8/2, and after dividing you get 4. The slope of the equation is 4.  

This means the equation has the greater slope.

What is the area of a parallelogram with a base of 0.56 cm and a height of 0.33 cm (to the nearest hundredths)? A) 0.18 cm2 B) 0
valentinak56 [21]

Answer: A) 0.18 cm²

Step-by-step explanation:

To calculate the area of a parallelogram you must apply the formula shown below:

A=b*h

Where b is the base and h is the height of the parallelogram.

You know the values of the base and the value of the height.

Therefore, when you susbstitute these values into the equation shown above, you obtain the following result:

A=0.56*0.33cm=0.18cm^{2}

A baseball stadium sells a slushy cup for $5 and $1 for every time you fill it. How much would you pay in total to drink slushy
Airida [17]

Answer:

y = 1x + 5

Step-by-step explanation:

Because you pay $5 for the cup once, and to refill it, you have to pay $1 as how many times as you want.

Explain the difference between an equation and an inequality. Write at least two of each, one of the form px+q and one of the fo
Triss [41]

Answer: One important difference between an equation and an inequality is that if you subtract one side of an equation from the other, you will get 0

In the case of an inequality, if you subtract one side from the other, you will get something other than 0

That’s an important fact about equations and inequalities that is often utilized in finding solutions.

When I was teaching I noticed that students frequently interpreted the =

sign to mean ‘find the answer’. It does not mean that. It only means that the expression on the left hand side has the same value as the expression on the right hand side.

Students who think that =

means ‘find the answer’ become confused when they see symbols like < , ≠

, or ≈

A further issue these days has to do with computational technology.

This issue has to do with variable assignment. In many programming languages, a statement like =+1x1

has the meaning, “Add one to the current value of x

and then reassign that value to x

.” However, the equation =+1x1

has no solution in traditional algebra.

Programming languages that use =

for variable assignment tend to use ==

to mean equality in our traditional math sense.

Though something like the meaning of =

might seem trivial and ‘obvious’ to many people, there’s actually a lot of subtle variations of understanding possible, and it is important to be aware of these nuances, because that is where confusions arise for students.
