Answer:
48
Step-by-step explanation:
25% of x = 0.25
12/0.25 = 48
“Same signs add and keep”
Negative minus negative you add them and keep the negative sign
-1 12/12
12/12= 1
=-2
Or make it into an improper fraction -1 5/12 is also -17/12
17+7= 24
-24/12 = -2
The answer will be 10 ft because its 10 cents per foot
Average rate of change means find the slope of the secant line. So if there is a function f(x) and you want to find the average R.O.C over the interval [a,b], it would be (f(b)-f(a))/(b-a)
1. (f(3)-f(1))/(3-1)= (0-(-2))/2= 1, so D.
2. Same concept; (8-4)/(3-1)=2, so A.
3. Again, (39-(-1))/5= 8, B.
