Read the instructions first then graph
Polya created his famous four-step process for problem solving, which is used all over to aid people in problem solving:
Step 1: Understand the problem.
Step 2: Devise a plan (translate).
Step 3: Carry out the plan (solve).
Step 4: Look back (check and interpret​

Step-by-step explanation:

Step 1:

Age of grace = x

Age of her son = y

Step 2:

   x > 20

x + y ≥ 60

Step 3:

    x +y ≥ 60

        y ≥ -x +60            

Step 4

(45, 22)

x > 20              ;     y  ≥ -x + 60

45 > 20           ;    22  ≥   -45 + 60

                            22  ≥ 15

725 parts per hour.

step-by-step explanation:

hi there, this answer is actually really simple.

you can set it up as 1450/2 or 3625/5 to find the answer.

they want to know how much per hour is being made, so you just divide.

1450/2=725.

and that's how many are produced per hour.

hope this . : )

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
