Answer:
53$
Step-by-step explanation:
They tell you the equation of how much the coin is worth after x amount of years
Step 1: Substitute x=19 into the equation y=2x+15
y = 2(19) + 15
Step 2: Solve for y
y = 2(19) + 15
y = 38 + 15
y = 53
Therefore the coin is worth 53 dollars after 19 years
Answer:
6x - 24y
Explanation:
Expand -3(10x + 4y): -30x - 12y
= ![\bold{-30x-12y+6\left(6x-2y\right)}](https://tex.z-dn.net/?f=%5Cbold%7B-30x-12y%2B6%5Cleft%286x-2y%5Cright%29%7D)
Simplify ![\bold{-30x-12y+6\left(6x-2y\right): \ 6x-24y}](https://tex.z-dn.net/?f=%5Cbold%7B-30x-12y%2B6%5Cleft%286x-2y%5Cright%29%3A%20%5C%206x-24y%7D)
= 6x - 24y
Mordancy.
Answer:
This can't really be factored, but it can be expanded slightly.
(3x³)³ = 27x⁹
Answer:
B.
