Give an example of an open equation.
An example of an open equation is:
3x + 5 = 2x + 10
3x + 5 = 2x + 10
How can you use an equation to make a prediction from a pattern?
You can use an equation to make a prediction from a pattern by identifying the relationship between the given data points. Once you determine the pattern, you can create an equation that represents that pattern. Using this equation, you can then plug in a value or a variable to make a prediction about the corresponding output or future data point in the pattern. By substituting the value or variable into the equation, you can solve for the predicted outcome. This allows you to use the equation to make accurate predictions based on the pattern established by the given data.
Pizza costs $1.50 per slice. Use a table and an equation to represent the relationship between the number of slices of pizza bought and the total cost.
Here is a table representing the relationship between the number of slices of pizza bought and the total cost:
Number of slices (x) | Total cost (y)
__________________________________
1 | $1.50
2 | $3.00
3 | $4.50
4 | $6.00
To represent the relationship using an equation, we can let "x" represent the number of slices and "y" represent the total cost. Since each slice costs $1.50, the equation would be:
y = 1.50x
This equation shows that the total cost (y) is equal to 1.50 times the number of slices purchased (x).
Number of slices (x) | Total cost (y)
