Answer:
y=x+6
Step-by-step explanation:
For every cubic yard, it equals to 27 cubic feet.
So, could have this fraction
And we want to convert 3 cubic yards into cubic feet.
We can express 3 cubic yards as
Now multiply the
fraction by the second fraction or the reciprocal of the second fraction to cancel out the yards^3 units.
So, 3 cubic yards to equal to 81 cubic feet.
Answer:
8
Step-by-step explanation:
Let the number be n
6*n = 16 + 4*n
6n = 16 + 4n
6n - 4n = 16
2n = 16
2n/2 = 16/2
n = 8
Step-by-step explanation:
The basic form of equation:
(x-h)²=4a(y-k),
(h,k)=coordinates of vertex
(h, k+a) = coordinate of focus
For given parabola:
axis of symmetry: x=2
(h, k) =(2,-3)
(h, k+a)=(2,5)
k+a=5
-3+a=5
a=8(distance from vertex to focus on the axis of symmetry)
equation: (x-2)²=4×8(y+3)
(x-2)²= 32(y+3)
Answer:
Infinitely many solutions.
Step-by-step explanation:
Let's solve your system by elimination.
x−3y=9;−x+3y=−9
x−3y=9
−x+3y=−9
Add these equations to eliminate x:
0=0
<u>Answer:</u>
Infinitely many solutions.
