9 would be the right answer for you second pic
Answer:

Step-by-step explanation:
f(x)=25-x^2 and g(x)=x+5
We need to find (f/g)(x)
(f/g)(x) = f(x)/ g(x)
we divide f(x) by g(x) and then we simplify

WE factor 25-x^2
25-x^2 = 5^2 - x^2 = (5-x)(5+x)


5+x or x+5 are same , so we cancel out x+5

Answer:
y = x + 3
Step-by-step explanation:
There is a slope of 1 and the y-intercept is at 3. Therefore m would be 1 and b would be 3
