consider the following image

I think that i got it but at the same time not sure but the value of a+b should be 14+20
Answer:
your question doesn't make sense if an electrician came to your house it would cost $40 then $55 dollars per hour but there is no way that you can solve that (40+(55•2)=150+55=205 which is already over $190 dollars
100 degrees - all angle measurements in a triangle will add up to 180 degrees (45+55 = 100, 180-100 = 80)
Answer:

Step-by-step explanation:
The range is set of all y-values. The range starts from minimum value to maximum value.
We don't have minimum value (approaching negative infinity.)
We have maximum value at x ≈ 2 equal 6.
Therefore the answer is
-inf <= y <= 6. But we don't usually write that. Instead, we cut out -inf and we get —
