3-(2x) I think I might be wrong but im pretty sure I'm right
I think the answer is choosing an odd number
Answer:
-8
Step-by-step explanation:
f(x) = 3x + 1
f(-3) = 3(-3) + 1
F(-3)=-9+1
f(-3)= -8
The average low temperature is -10.
-8+(-13)+(-4)+(-9)+(-16)= -50/5=-10
We need to know this:
If Δ > 0 we have two and different solutions
If Δ = 0 we just one solution
If Δ < 0 we don't have real solutions
