The function T(d) gives the temperature, in degrees Fahrenheit,
of Des Moines, d days after the first
day of fall.
Explain what the equation below
means in this situation. (Make sure
you explain the meaning of both
numbers.)

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

i would guess 26 because this isnt a sequential pattern or its to short to know
