Answer:
(x, y) = (5, 1)
Step-by-step explanation:
To <em>eliminate</em> x, you can double the second equation and subtract the first.
... 2(x +4y) -(2x -3y) = 2(9) -(7)
...11y = 11 . . . . . simplify
... y = 1 . . . . . . divide by 11
Using the second equation to find x, we have ...
... x + 4·1 = 9
... x = 5 . . . . . subtract 4
_____
<u>Check</u>
2·5 -3·1 = 10 -3 = 7 . . . . agrees with the first equation
(Since we used the second equation to find x, we know it will check.)
Answer:
150,000*3^t for 6 hour increments (t=1 is 6 hours t=2 is 12)
150,000*3^(t/6) for hourly increments, each t is 1 hour.
Step-by-step explanation:
Well super simply you could do 150,000*3^t where t is measured in 6 hour intervals. so t=1 is 6 hours, and to get 1 hour you would need to do t=1/6
If you want t to be an increase of every hour you would just need to adjust, like I showed before 1/6 gets one hour so 150,000*3^(t/6) would be the model where every t increases by 1 hour.
I need help with these too ugh someone help me

Answer:
Variables:
→ The number of hours the worker worked
→ The number of shirts the worker made.
System fo equations:
Step-by-step explanation:
Let be the number of hours the worker worked and the number of shirts the worker made.
Since:
- Jason must pay the worker $25 per hour (which can be represented with
). - He must pay $1.75 per shirt for material costs (which can be represented with
). - The total expenses were $270.
You can write the following equation:
Knowing that the worker created an average of 5 shirts per hour, you can write the other equation:
Therefore, with this equations you can set up the following system of equations, which could be used to determine the number of hours the worker worked and the number of shirts the worker made:
