-3(-4y+3)+7y
First multiply -3 by the terms in the parentheses
-3(-4y+3) = 12y -9
Your expression now looks like
12y -9 +7y
Then combine the terms containing the variable y
12y + 7y = 19 y
Your final answer is
19y - 9 (answer choice A)
$ 524.288
Step-by-step explanation:
We will use the sum of a geometric series;
S = (first term)(1-r^n)/(1-r)
= 1(1 - 2^n) / (1 - 2)
= - (1 - 2^n)
= 2^n - 1
2 ^ (20 – 1)
2 ^ 19
= 524,288 cents
100 cents = 1 dollar
524,288 cents = 524,288/ 100 dollars
= $ 524.288
