The answer would be choice a they are both functions
Using rounding I would change 198 to 200 and 727 to 730.
200 + 730 = 930. Some would change the 727 to 700 but I see no need to do that. My answer will be closer using 200+730.
You can also get the exact answer like this - when you raise 198 to 200, you raised it by 2 so to compensate, take 2 away from the other number and 727 becomes 725
I can do 200 + 725 = 925 in my head and that happens to be the exact answer.
<span>17=-b+10
Subtract 10 from both sides
7= -b
Divide both sides by -1
Final Answer: -7= b</span>
When writing functions, f(x) is essentially y. So solve for y by subtracting x from both sides. Your new equation is y=-x+14. Now, make a table of various x values (such as 0, 2, 4... etc) and a y column. Input the given x value into the x column and the equation y=-x+14 and solve for y. Now, put the solution for y into your y column. To show your work on one place, you could put an extra column in between x and y, and label it y=-x+14, where you will solve for y within the column, if that makes sense. Hopefully this can be useful in the future :)
