Y= 3 -x (1)
3x + 4y = 1 (2)
Substitute (1) for y in (2)
3x + 4(3 - x) = 1
Expand, simplify and then solve for x
3x + 12 - 4x = 1
3x - 4x = 1 -12
-x = -11
x = 11
Answer:
4 = 
Step-by-step explanation:
We're looking for the volume, since it's trying to find out the cost for filling the entire box.
We have our length, width, and height.
8, 6, and 1.
We're multiplying 8, 6 1, and 0.3 since it is $0.3 per sq ft,
Our equation is:
0.3 (8x6x1) = x
8 x 6 x 1 = 48.
48 x 0.3 is 14.4
$14.4 is your answer
Hope this helps!
The geometric mean would be 37.9
The most important part of this problem is reading the problem carefully and then solving it. Most of the required information's are already given in the question. Let us now focus on the problem in hand.
(12z^2 - 7z -12)/(3z^2 + 2z - 8) = [12z^2 - 16z + 9z - 12]/[3z^2 + 6z - 4z - 8]
= [4z(3z - 4) + 3(3z - 4)/[(3z(z + 2) -4(z + 2)]
= [(4z + 3)(3z - 4)]/(z + 2) (3z - 4)]
= (4z + 3)/(z + 2)
The above deduction is the simplified form. I hope that this is the answer that has come to your desired help.
