Answer:
part one:
6 3
22 1
30 0
part two:
0.50*s+4*a=15
Step-by-step explanation:
part one:
firstly:
6 individual songs cost 6*0.50= 3 dollars
she has 15 dollars so after downloading 6 individual songs that cost 3 dollars together
it means that she has only 15-3=12 dollars to download full albums
so 12/4=3 albums
because 4 dollar cost one album and with 12 dollars she can buy just 3 albums
secondary:
she downloaded 1 album
and one album cost 1*4=4 dollars
she has 15 dollars ,after buying 1 album
she has 15-4=11 dollars
so she can download 11/0.50=22 individual songs
so she can download 22 individual songs.
the last one:
she downloaded 30 individual songs
that all together cost 30*0.50=15 dollars
but she has 15 dollars at all so she cant buy any album because she spent all her money in individual songs.
because 15-15=0 money left
part two:equation
0.50*s+4*a=15
Answer: yes because they both go to the 0 and has the same shape.
Step-by-step explanation: yes
Answer:
Step-by-step explanation:
They give us the slope so this makes it a lot easier.
Slope intercept formula is
y=mx+b
(m) is slope
(b) is y intercept
we can apply our slope into the formula
y=-3/2x+b
Now we can replace (y) with the (y) from the ordered pair they gave us (4, 10), and replace the (x) with the (x) from the ordered pair they gave us
(4, 10)
10=-3/2(4)+b
Now solve
10=-6+b
Add 6 to each side
16=b
Now we we put both our slope and intercept into the formula.
Answer:
D
Step-by-step explanation:
without knowing anything about the background of the function and what it is used for, I give it the max. possible domain (the set or interval of all possible input values).
and so,
Defined for all m >= 0 and n >= 0.
there is no information provided that would eliminate m = 0 or n = 0.
