Answer:

-2

Step-by-step explanation:

The functions of f(x) and g(x) are given

For f(x)+g(x)=0 , functions f and g should be in opposite sign

We can observe that at x=−2 , f(x)=2 and g(x)=−2

Therefore f(−2)+g(−2)=0

So the correct option is D (-2)

there would be a 99% chance of a red marble being pulled out or even a 1% chance.

because of their being five green marbles and six red there is always a chance you could pull out any one of the colors.

but i believe that both of the answers are 1/2

but im not 100% sure

We are given with the rectangle shaped deck which has  a width of 29 feet and a perimeter of 134 feet. the perimeter of a rectangle is equal to twice the sum of length and width. hence the equation goes : 

134 ≤ 2* (29 + L)
67 <span>≤ 29 + L 
38 </span><span>≤ L 

length should be greater or less than 38 feet</span>

Caroline babysat for two families - the Nelsons and the Smiths. Use the info below to compare her earnings.
Ket [755]

Answer:

She earns $6.50 from the Smiths which is 25 cents more than she earns at the Nelsons.

Step-by-step explanation:

To solve this problem you must find the hourly rate she earns at the Smiths.  This will allow you to compare to the hourly rate that is given for the Nelsons.  To find the Smiths hourly rate divide $39 by the 6 hours she babysat there.  This will have the hourly rate.  39/6=6.5.  This means she earns $6.50 an hour for the Smiths.  When comparing the rates it is clear that she earned 25 cents more at the Smiths.
