It is a good idea to check to see if your answer is reasonable because a. if your answer is reasonable, you have probably done the problem correctly.
You simply divide 678 by 3 and get 226.
X+(x+2)+(x+4)= 66
3x+6=66
3x=60
x=20
20,22, and 24. so 20 is the answer
The systems will intersect at (1,-4), and i think the system has infinite solutions (not sure)
Answer:
Step-by-step explanation:
As per definition of the function, every x- value (input) has exactly one corresponding y-value (output)
<u>We can see on the table:</u>
- x = 3.45 and y= 1.72
- x = 3.45 and y = 3.36
Two same input values with different outputs.
So this not a function
