Pls helppp me , how much does each type of box weight ?

small box = 6kg

large box = 18.5kg

Step-by-step explanation:

8 large + 3 small = 166kg

2 large + 5 small = 67kg

Our equations are:

Multiply by -4 the second equation to make l eliminable.

Now add both equations.

-------------------------------------------

Solve for s;

Now replace the value of s in any of your main equations to find l.

Now replace both l and s in the equations to find if they're the real values that satisfy the equation.

Therefore we can conclude that these are the real values that satisfy the equations.

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
