Equations with Independent and Dependent Variables
Common Core Standard: Use variables to represent two quantities in a real-world problem that change in relationship to one another; write an equation to express one quantity, thought of as the dependent variable, in terms of the other quantity, thought of as the independent variable. Analyze the relationship between the dependent and independent variables using graphs and tables, and relate these to the equation.
Dependent variable – is a variable that changes because of the other variable or depends on the other variable
Independent variable –is a variable that is not impacted by other variables
Dependent and independent variables are very common in the real world
Example: Most coaches will say that the longer a player practices a sport the better the player will be at the sport.
o The dependent variable is the player’s ability, as it relies on the length of a practice
o The independent variable is the number of hours the player practices, because the player’s ability does not
impact the amount of time the player practice
Answer:
6
Step-by-step explanation:
The mode is the number which appears most often in a set of numbers in this case that would be 6 because it appears twice
Answer:
1,12/ Not a solution
2,10/ solution
4,5/ solution
6,10/ not a solution
12,8/ not a solution
18,6/ not a solution
Step-by-step explanation:
all you have to do is put it into the equation.
for example:
1,12
1x1+12x3= $37
1x1+12x1.5= 19lbs
This is not a solution because he can carry it but doesn't have the money to buy it.
Answer:
D
Step-by-step explanation:
12z+42=73
subtract 42 from both sides.
12z=31
divide 12 on both sides to get:
z=2.58
