Answer:
(-2,-4)
Step-by-step explanation:
The given system is
Add both equations to eliminate y
Simplify both sides to get:
Divide both sides by 2
Put x=-2 into one of the equations say, x+y=-6 and solve for y
The solution is (-2,-4)
Answer:
f(6) = 182
Step-by-step explanation:
f(1) = 1
f(2) = 2
f(3) = 2f(2) + 3f(1) = 2(2) + 3(1) = 4 + 3 = 7
f(4) = 2f(3) + 3f(2) = 2(7) + 3(2) = 14 + 6 = 20
f(5) = 2f(4) + 3f(3) = 2(20) + 3(7) = 40 + 21 = 61
f(6) = 2f(5) + 3f(4) = 2(61) + 3(20) = 122 + 60 = 182
