Answer:
y=7x-5
Step-by-step explanation:
The x-intercepts are indeed -1 and 1.
The increasing intervals are listed as (-1, 0) u (1, infinity) not because -1 and 1 are not included points of the function, but because the function is not differentiable in those points, so you can't tell whether the function is increasing or decreasing there.
Hey! I'll provide you the answers!
First you want to simplify the equation using cross-multiplication.

Finally, you would want to divide both sides by 15.
n = 161
If K=C+273.15
and in a. C=200° then K=200+273.15
3x -4 (5 - x) = 7x -20
3x-20+4x=7x-20
7x-20=7x-20
