The length should be 96. It just divided 8,160 with 85 and this popped up!
Answer:
First option: All functions have dependent variable (At least)
Second option: All functions have an independent variable.
Fifth option: A horizontal line is an example of a functional relationship.
Step-by-step explanation:
By definition, a relation is a function if each input value has one and only one output value.
A function have a at least a dependent variable and an independent variable. For example, given a function:
The dependent variable is "y" and the independent variable is "x".
The Domain of the function is the set of possible input values and the Range is the set of possible output values,
Vertical lines have undefined slope. Since the value of "x" never changes, a vertical line is not an example of a functional relationship.
In the case of Horizontal lines, for any x-value you get the same y-value. These are called "Constant functions".
Based on this, the following statements are true:
- All functions have a dependent variable (At least).
- All functions have an independent variable.
- A horizontal line is an example of a functional relationship.
Answer:
B
Step-by-step explanation:
This is proportional because the number of calories burned is directly proportional to the amount of time spent on the treadmill
Answer:
Step-by-step explanation:
a + c = 92.....c = 92 - a
8a + 5c = 688
8a + 5(92 - a) = 688
8a + 460 - 5a = 688
3a = 688 - 460
3a = 228
a= 228/3
a = 76 <==== adults
a + c = 92
76 + c = 92
c = 92 - 76
c = 16 <=== children
