Answer:
-9
Step-by-step explanation:
g(-6) = -6 - 3
g(-6) = -9
x = - 9
Given g(x) = - x - 3 and g(x) = 6, then equate, that is
- x - 3 = 6 ( add 3 to both sides )
- x = 9 ( multiply both sides by - 1 )
The last one is rational because it is a terminating decimal.
0.10x + 0.13y = 10780
x + y = 100000
x = 74000 --------------10%
y = 26000 --------------13% (more risky)
