PLS HELP ME THIS IS DUE IN A FEW HOURS(i need a graph too pls)
emmainna [20.7K]

Answer:

Yes, the total cost of Lacey lesson is a split function of hours scheduled

Step-by-step explanation:

The amount Lacey pays for each hour of golf = $15

The amount Lacey pays for equipment rental = $10

The amount Lacy pays for equipment rental for a 3 hours long lesson = $5

Therefore, we have

Let C represent the total cost of Lacey lesson and let t represent the number of hours, we have;

C = $10 + t × $15 for 0 ≤ t ≤ 3

C = $5 + t × $15 for t > 3

Therefore, the total cost of Lacey lesson is a split function of hours scheduled

Can anyone help me please?
Nadya [2.5K]

Answer:

s ≤ -18

Step-by-step explanation:

Multiply both sides of the inequality by -3. Since the multiplier is negative, you need to reverse the comparison symbol.

(-3)(-s/3) ≤ (-3)(6)

s ≤ -18

_____

If you multiply by a positive number, you don't need to reverse the symbol. Hence multiplying by 3 gives ...

-s ≥ 18

You can now add s to both sides:

0 ≥ 18 + s

and subtract 18 from both sides:

-18 ≥ s

Of course, this is the same relationship as ...

s ≤ -18
