This may look scary, but all you have to do is distribute, first:
Now it's much easier (remember to distribute the negative):
So, the entire thing simplifies to
-2c. NEAT!
I think it is C because it is in the positive and negitive
Answer:
The laptop was 934 dollars.
Step-by-step explanation:
The equation you should use to solve this is 120 + 11 (74) since the down payment was a one-time thing and she pays 74 dollars for 11 months, not including the first month.
When you solve that, you will get 934 which is the correct answer.
For questions 9 through 12, plug in the term you're looking for in for x:
9. y=10(20)-2=298
10. y=10(9)-2=88
11. y=5(2^5)=160
12.y=5(2^7)=640
For questions 13 through 16, plug the values 1 through 5 in for x, one at a time:
13. y=4^1=4, y=4^2=16, y=4^3=64, y=4^4=256, y=4^5=1,024
14. y=(-3)^1=-3, y=(-3)^2=9, y=(-3)^3=-27, y=(-3)^4=81, y=(-3)^5=-243
15. y=-3^1=-3, y=-3^2=-9, y=-3^3=-27, y=-3^4=-81, y=-3^5=-243
16. y=10^1=10, y=10^2=100, y=10^3=1,000, y=10^4=10,000, y=10^5=100,000
For question 17, plug 4 in for n:
17. f(4)=5^4=625
