She needs to have 4 hours a week for the next 7 weeks.
To make this true we know need 4x, x as for week (time).
We also need to have it done with 7 weeks, so we will need 7 weeks x 7 days which would be 49 days total.
Now to put it together,4(x) and place the number of weeks to get the total number of hours. Example on week 7 hour number of hours she played is (4*7)=28 hours total.
f(x) = 4x + 14 is the function.
14 is from the first week. Therefore, that's the function of the total hours she played.
Okay, so if there’s a can that holds 16 cups, and she only fills it halfway, there are 8 cups to water the plants with.
8/15= 0.53 Cups Per Plant.
F^-1(x)=4x
I hope this helps
Step 1: -9+n=-18. You would add the inverse to both sides, meaning you’d add nine to the negative nine to cancel it out and then then 9 to -18.
-9+n=-18
+9 +9
That would leave you with the equation: n=-9, since -18 plus a positive 9 equals a negative nine. You’re final answer is n= -9.
You can check you answer by substituting the variable with the solution (-9).
-9 + -9= -18
If the lines are parallel, they have no solutions because they never touch
