Answer:
The answer to your question is: letter B
Step-by-step explanation:
Function definition: a function is a relation from a set of inputs to a set of outputs.
The most important about functions is that each input is related to one and only one output. Then there are not repeated values of inputs.
In the exercise, the inputs are -10, -25, -5, and the outputs are 5, 10, 15 and 20.
So, to solve this exercise, look for a number in the options that will not be repeated in the inputs,
Then,
- 20 is a possible option because is not repeated
-5 is not an option to complete the table because 5 already exist.
- 15 is a possible option because is not repeated previously.
Subtract the 2x and divide by -4. y=1/2x-2 or y=x/2-2
Answer:
645/3 = 215
Step-by-step explanation:
You can use long division to find the answer.
5≤x≤9 it can also be reversed as 9≥x≥5 which is the same thing
Does x equal 4 ?if it does then a) -100
b) 25
