a = 8
b = - 6
c = 13
Answer:
i can't understand it as well
The sum of function is a way of adding two or more functions together
The values of x for which f(g(x)) = 0 are -2/3 and -1/3

The sum of function is a way of adding two or more functions together
Given the following functions
f(x) = x² - 2x
g(x) = 6x + 4
f(g(x) = f(6x +4))
f(6x+4) = (6x+4)² - 2(6x+4)
(6x+4)² - 2(6x+4) = 0
(6x+4) = 0 and 6x+4-2 = 0
x = -2/3 and -1/3
Hence the values of x for which f(g(x)) = 0 are -2/3 and -1/3

4x + 2y = 20
3x - y = 10
Multiplying second equation by 2.
6x - 2y = 20
Adding to the first,
10x = 40
x = 4
y = 3x - 10 = 3(4) - 10 = 2
Answer: (4, 2)
Check:
4(4) + 2(2) = 16+4 = 20, good
3(4) - 2 = 12 - 2 = 10, good
