Rewrite (1st) equation
-x - 2y = - 9
multiply the (1st) equation by 3
-3x - 6y = -27
now you have
-3x - 6y = -27
3x - 6y = -15
-----------------------add
-12y = -42
y = 3.5
2(3.5) = -x + 9
7 = - x + 9
x = 2
answer
(2 , 3.5)
105(12) = $1,260(.15) = 189
189 is the fifteen percent times the total amount at the end of the year, add it plus the year total, and you have (drumroll please) $1,449 total.
So C. $1,449
His total account will have 1485.06 in it after everything is said and done.
So your question was not very clear but with (f+g) im guessing thats f(x)+g(x)
So first we add them x^2+4x-32 + x-4 then we will get x^2 + 5x - 36
Then we need to multiply both
(x^2+5x-36)(x^2+5x-36)
=
(x^2+5x-36)^2
The only reason im not solving it out is because it yields large numbers and you might not understand.
Answer:
y=17x
