Answer:
m = (8+3n)/4
k = 55j+20
Step-by-step explanation:
4m -3n = 8
Add 3n to each side
4m-3n+3n = 8+3n
4m = 8+3n
Divide by 4
4m/4 = (8+3n)/4
m = (8+3n)/4
(k-20)/5 = 11j
Multiply each side by 5
(k-20)/5 *5= 11j*5
k-20 = 55j
Add 20 to each side
k-20+20 = 55j+20
k = 55j+20
Answer:
See below
Step-by-step explanation:
Recall that we need to use the equation y=a(x-h)^2+k. This means that h=-2 instead of 2 otherwise it would've been (x-2)^2-6. So Renaldo made the mistake of identifying h as 2 instead of -2. The second mistake Renaldo made is that since k=-6, there should be a vertical shift of 6 units down not 2.
Answer:
It costs $1.26 to download a single song.
Step-by-step explanation:
Cost in function of the number of musics:
The cost c, in function of the number of musics downloaded s, is given by the following equation:
c = 1.26s.
How much does it cost to download a single song?
One song, so s = 1.
c = 1.26*1 = 1.26.
It costs $1.26 to download a single song.
