The ratio of pop songs to rock songs you download is 5:4, and 40 are pop songs. You want to find out how many rock songs there are.
First, add the ratios together: 5+4=9. This means that 9 will be your denominator, so 5/9 songs are pop and 4/9 songs are rock.
Now you know that pop songs account for 5/9 of the songs, this means that 40 is 5/9 of the total songs.
To find out how much 4/9 is, you need to divide 40 by 5 to get 1/9 and times that number by 4 to get 4/9:
40÷5=8×4=32 songs are rock songs

Answer:
(0,0), (-8,-8), (4,-8)
Step-by-step explanation:
(0 * 0, 0*0) = (0,0)
(-4*2,-4*2) = (-8,-8)
(2*2,-4*2) = (4,-8)
I am not 100% certain but i believe it goes as follows:
4 ( 1 + d ) + ( 3 + e)
4d + 12e
