Answer:
(18, ∞)
Step-by-step explanation:
(18, ∞) is the only option that works. if we ignore the "greater than" sign, and just set the function equal to -12, we see that x-10=-12 would give us x=-2. If we plug in -3 for x, we get -13, which is less than -12. if we plug in -1 for x, we get -11, which is greater than -12. Therefore, with the function only having one critical point (zero), we know that every value greater than -2 is a solution. Technically, the full solution would be (-2, ∞). however, the only answer available meeting the criteria would be (18, ∞).

Answer:
146 whistles
Step-by-step explanation:
First, convert 122 feet to inches, by multiplying it by 12
122(12)
= 1464
Divide this by 10 to find how many whistles he can make
1464/10
= 146.4
Since we can only have a whole number of whistles, we have to round down to 146.
So, he can make 146 whistles
Answer:
$370
Step-by-step explanation:
You already have 90 dollars so we can put that to the side for right now
If you're charged $35 at an hourly rate for 8 hours then you have to multiply the two together
30 x 8 = 240
5 x 8=40
240 + 40=280
Now is when your $90 dollars comes in. Now just add the two together and you'll end up with your final answer
280+90=370
