Answer:
She can create a function for the total savings in terms of the time x by adding the two functions together. The new function should look like this:
T(x)=S(x)+a(x)
So now we can substitute the given functions:
T(x)=450+6(x-2)
But this function can be simplified for it to be easier for her to calculate her total amount of savings. We can do that by distributing the 6 into the parenthesis. This is, multiply the 6 by both the x and the -2, so we get:
T(x)=450+6x-12
and now we can combine like terms. We can subtract 12 from 450 so we get:
T(x)=6x+438
And that will be our final function.
Answer:
12
Step-by-step explanation:
9+3=12. therefore 12 is your answer

Answer: C: y = 4x + 20
Step-by-step explanation:
4x is multiplying 4 by the number of levels, and you add the castles he's already found which is 4*5 =20.
