Answer: .42857 liters of pure water
Step-by-step explanation:2.4 = .7w + 2.1
2.4 - 2.1 = .7w
.3 = .7w
w = .3%2F.7
Answer:
B
Step-by-step explanation:
The product of the difference of x and 5 and the sum of x and 3
If the garden were in the shape of a square, all of its sides would be of equal length. so if you divide 240 by 4 sides, each one would be 60 feet. Then, to find the square garden's area, you multiply 60 x 60 = 360 feet².
If the garden was 50 by 70, you would multiply the two values together to find the area, which is 350 feet².
Because 360 > 350 , Tyler's design would yield the maximum area for a garden
Hope this helps :)
Answer:
Both expressions are = to 11 when x is 2.
Therefore, the expressions are equivalent.

Answer:
- (c1, c2, c3) = (-2t, 4t, t) . . . . for any value of t
- NOT linearly independent
Step-by-step explanation:
We want ...
c1·f1(x) +c2·f2(x) +c3·f3(x) = g(x) ≡ 0
Substituting for the fn function values, we have ...
c1·x +c2·x² +c3·(2x -4x²) ≡ 0
This resolves to two equations:
x(c1 +2c3) = 0
x²(c2 -4c3) = 0
These have an infinite set of solutions:
c1 = -2c3
c2 = 4c3
Then for any parameter t, including the "trivial" t=0, ...
(c1, c2, c3) = (-2t, 4t, t)
__
f1, f2, f3 are NOT linearly independent. (If they were, there would be only one solution making g(x) ≡ 0.)
