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.)

Answer:
x=3y+2
14-y=3y+2
12=4y
3=y ANSWER 1: One of the numbers is 3.
.
x=14-y=14-3=11 ANSWER 2: The other number is 11.
Answer:
77
Step-by-step explanation:
to start off the "difference" is the way to say total in subtraction
you would have to subtract 87 and 10 to find the difference
87 - 10 = 77
77 is the difference between their times
