substitute x for y-1
2(y-1)-y=6 distribute
2y-2-y=6 subtract y in 2y
y-2=6 add 2 to get y by itself
y=8
Put y back into equation x=y-1
x=8-1
X=7
Answer:
5
Step-by-step explanation:
cos 60° = y / 10
y = 10 * 1/2 = 5
Answer:
D. multiplying the area of the base by the height
Calculate the area of the base (which is a circle) by using the equation πr². Then, multiply the area of the base by the height of the cylinder to find the volume.
6y=-36
y=-6
-4x+12=-12
-4x=24
x=-6
(1/4)=0.25
0.25*0.25*0.25=0.015625
