Answer:
a
Step-by-step explanation:
Answer:
1. 33
2. 3x - 3y + 7z
Step-by-step explanation:
combine like terms on the second one.
3x - 3y + 7z
solve for the first one 22 + 18 - 7
18 - 7 = 11
11 + 22 = 33
Answer:
The domain of the function is R i.e. any real value.
Step-by-step explanation:
The given figure is a graph on the coordinate plane of the function
Now, the domain of a function means that the values of x (Independent variable) for which the function is valid i.e. the y values are real.
It is clear from the equation given above that for any real value of x there will be a real corresponding value of y.
Therefore, the domain of the function is R i.e. any real value. (Answer)
Change 15/20 to 3/4
Now we have

multiply 6 to 3= 18 ÷ 4 = 4.5
x = 4.5
