Answer:
12
Step-by-step explanation:
we would do 475 divided among 40
475/40=11.875
but we would not use 11.875 so let's make it 12$
So if you look at the equation you can see the y-intercept.
slope y-intercept
↓ ↓
y = x - 2
The y-intercept is where the line crosses the y-axis. So which ever graph has -2 as the y-intercept in correct...Its more complex when the graphs have the same intercept but in this case this should be easy to find.
So looking at the graphs you can see that the 3rd graph is the correct answer.
I hope this helps love! :)
Answer:
Buy individual songs
Step-by-step explanation:
Considering that individual 6 songs each $0.99 will cost Martha a total of 6*$0.99=$5.94 and also individual 3 songs for $1.29 will mean he incurrs a sub-total cost of 3*1.29=$3.87
Total cost of buying 9 individual songs will be C=5.94+3.87=$9.81 which is less than the cost of the whole album. Therefore, it is recommended to buy individual songs instead of album for this case since the total cost of individual songs that the buyer is interested in is less than the total cost of an album
Use proportions for all of them, for #1 use the proportion 12/30 = 9/a based on corresponding sides and then cross multiply. a=22.5 For #2 use the proportion y/35 = 64/40 based on corresponding sides and then cross multiply, y=56 For #3 use the proportion 42/? = 54/36 and then cross multiply, ?=28
