So just divide 100 by 25 which equals 4 then divide 120 by 30 which also equals to 4 and if the rest equal 4 then its proportional (1)
And then same for 2 and 3 just divided the bottom by the top and if they all get the same answer they are proportion and if one is not the same then it’s not
For the grids if the dots are line diagonally straight and it starts at the 0 then it’s proportional if not then it’s not
Hope this helps :)
Answer: 2: an equation in the form y = mx + b
1. An x/y table may have two entries with the same x; not a function in that case.
2. That's a line with a slope; for each x there's a single y, definitely a function
3. Ordered pairs -- like the table, the same x with different ys is possible, which wouldn't be a function.
4. List of numbers -- a list isn't a function, at least not without more context
Ft (full time)= $2,400/ monthpt (part time)= $200/ week15% taken from taxes------------------------- 1 year= 12 months; 1 month= 4 weeks (12*2,400) + (4*12*200)= $38,400 you made in a year I set up the problem this way because you want to know how much you made that whole year, so if there are 12 months in a year, and you get paid $2,400 a month, then from your full time job you ear (12*2,400). From your PT job you make $200 a week, there are 4 weeks in a month and 12 months in a year, so to calculate what you earned from your PT job, you do: 4*12*200 15% of what you made is deducted from taxes:0.15(38,400)= $5,760 After taxes, you made:$38,400-$5760= $32,640
7.50
25% also equals 1/4 so divide 130.00 by 4 which equals 32.50
subtract 32.50 from 130.00 which equals the cost, 97.50
97.50 minus 90$ is 7.50, therefore that is the answer
