Answer:
20 nickels and 26 dimes
Step-by-step explanation:
- She has $3.60 in nickels and dimes
- a nickel is $0.05 and a dime is $0.10
- let n be the number of nickels and d be the number of dimes
- thus the first equation is 3.6 = 0.05n +0.1d
- If she has 46 coins then n + d = 46
- then n = 46 - d
- sub n = 46 - d into 3.6 = 0.05n +0.1d
- 3.6 = 0.05(46 - d) + 0.1d
- 3.6 = 2.3 -0.05d+0.1d
- 1.3 = 0.05d
- 26 = d
- sub d = 26 into n+d=46
- n+26=46
- n=20
- Check by subbing n=20 and d=26 into 0.05n +0.1d
- 0.05(20) +0.1(26)
- 1+2.6 = 3.6
Answer:
1.
hours / views
1. / 125
2. / 250
3. / 375
4. / 500
5. / 625
2.
f(x)= 125 x views=125.hours
The slope of the function equals the visits of each hour.
3. (1;125) (2;250) (3;375) (4;500) (5;625)
4. "views as a function of hours"
5. in 12 hours the website will have f(12)=125 . 12 = 1500 views.
we can see in the plot that the line gets to that number for 8
