Answer:
180 CDs
Step-by-step explanation:
So if Sam has 84 CDs, and the ratio from Sam to Alice is 7:8, we can do 84/7=12 so each number is equal to 12. Then we add up 7 and 8 and get 15, so we do 15*12 and we get 180.
When 1 is added to another 1 they join together to form a 2. Bruh idk what 1+1 long method is. But I hope it helped.
Y = x + 4
y = -2x - 2
x + 4 = -2x - 2
x + 2x = -2 - 4
3x = -6
x = -6/3
x = -2
y = x + 4
y = -2 + 4
y = 2
solution is (-2,2)
Vertex: (1,-6)
Axis of symmetry: x=1
Hope this helped!
The slope intercept form is written as y=mx+c
7x+20=-5y
(-7/5)x-4= y
Hope I helped :)
