Over which interval(s) is the function decreasing?
Answer:
A. {3,4}
Step-by-step explanation:
In order to find the x values which would make the entire function undefined, you would have to factor the bottom equation. Factoring x^2+7x+12 gives you (x+3)(x+4). If you set each of these equal to 0, you end up with the x values being 3 and 4.
In this question we already know the value of 'b' so put the value b=2 in the equation
=|4(2)-8| + |-1-(2)^2| + 2(2)^3
=|8-8| + |-1-4| + 2(8)
=0 -5 +16
=11
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
